VMware Virtual SAN 6.0: Data Encryption with Hytrust DataControl

VSAN-Hytrust

Customers from different industries and institutions are very interested in Virtual SAN as a storage solution not just because of the technological value it delivers today, but because of the product’s undeniable value around operational efficiency, ease of management, and flexibility.

Some of these customers are from financial, healthcare and government institutions, and conduct their business in areas that are governed by regulatory compliance laws such as HIPPA, PCI-DSS, FedRAMP, Sarbanes-Oxley, etc. These laws demand compliance with numerous security measures, one of them being the ability to guarantee data integrity by securing data with some form of encryption.

Today Virtual SAN does not include encryption as one of its data services as this feature is currently under development for a future release. Now, when considering Virtual SAN as a potential solution wherever data encryption is a requirement based on regulatory compliance laws, it’s important to know what options are currently available.

In Virtual SAN the encryption data service capabilities are offloaded to hardware-based offerings available through Virtual SAN Ready Nodes. Data encryption data services are exclusively supported on Virtual SAN Ready Node appliances that are comprised with all of the certified and compatible hardware devices that provide encryption capabilities such as self-encrypting drives, and/or storage controllers. The Virtual SAN Ready Node appliances are offered by just about all the OEM hardware vendors that are part of VMware’s ecosystem.

An alternative option to the Virtual SAN Ready Nodes is a software based solution developed and offered by a company called Hytrust. Hytrust is one of the members of VMware’s partner ecosystem whose business is focused around the delivery of data security services for private and public cloud infrastructures. The solution I want to highlight in particular is called Hytrust DataControl.

Hytrust DataControl is a software-based solution that is designed with the capability of protecting virtual machines and their data throughout their entire lifecycle (from creating to decommission). Hytrust DataControl delivers both encryption and key management services.

This solution is built specifically to address the unique requirements of private, hybrid and public clouds, combining robust security, easy deployment, exceptional performance, infrastructure independence, and operational transparency. Hytrust DataControl ease of deployment and management capabilities complies with one of the main principles of Virtual SAN which is simplicity and ease of management.

Hytrust DataControl virtual machine edition is based on a software agent that encrypts data from within the Windows or Linux operating system of a virtual machine, ensuring protection and multi-tenancy of data in any infrastructure. DataControl also allows you to transfer files between VMs, so you can securely migrate stored data from your private to the public cloud.

The deployment of the Hytrust DataControl solution and installation and configuration of the software is done in a couple of easy steps which take just a few minutes. Once the software is resident, any data written to storage by an application will be encrypted both in motion, as it travels securely through the hypervisor and network, and also at rest on the Virtual SAN datastore.

Virtual SAN Certification & VCG Update

The Virtual SAN product team is pleased to announce that last week we released new certified components (I/O controllers, SSDs and HDDs), new Ready Nodes and a new Hardware Quick Reference Guide for Virtual SAN 6.0 along with a new and improved VCG page.  Please see updated links below:

Updated Virtual SAN VCG

Updated Virtual SAN Hardware Quick Reference Guide

Updated Virtual SAN Ready Nodes

 

How many new components and Ready Nodes do we have listed for Virtual SAN 6.0?

We now have 26 I/O controllers, 170 SSDs and 125 HDDs (and counting) supported on Virtual SAN 6.0.   In addition to the Virtual SAN 5.5 Ready Nodes, we have 8 new Ready Nodes for Virtual SAN 6.0  (Cisco – 4 Hybrid, Dell – 1 Hybrid, Hitachi – 1 Hybrid, Super Micro – 1 All Flash & 1 Hybrid).

We expect this list to grow very quickly.  We have a number of components that are currently getting certified and we plan to add new certified devices and Ready Nodes to the VCG on a weekly basis.

 

How does the Virtual SAN Certification process work?

The VMware Virtual SAN team treats hardware certification very seriously.  I/O controllers play a very important part in determining the stability and performance of a Virtual SAN cluster and need to be able to withstand high I/O under stress conditions.

The I/O controllers are put through a rigorous I/O certification process while the HDD, SSD and Ready Nodes  are put through stringent paper qualifications.

We run a I/O controller card through a 3-week-long certification test plan (the certification is done by VMware or by the partner) that stress tests the card across many dimensions, particularly in high load and failure scenarios to ensure the card can withstand the level of I/O pushed down by Virtual SAN even in the most adverse situations (example: rebuilds and resyncs triggered due to host failures).

If there are issues identified, we work closely with our controller vendor/OEM partner to resolve them and re-run the entire test suite after resolution.  Sometimes an updated firmware or driver version addressing the issue is required from the vendors before we can proceed with more testing.

Only controllers that fully pass the test criteria laid out in the above process are listed on the Virtual SAN VCG.

 

Are separate I/O controller certifications required for different releases?

Yes, we require controllers to be recertified whenever any of the following change:

  • Virtual SAN Release version (eg: 5.5 to 6.0)
  • The controller driver version
  • The controller firmware version

We also certify the same controller separately for Virtual SAN All Flash vs Hybrid since the caching and I/O mechanism are different for these two configurations and we expect controllers to behave differently with varying levels of I/O.

 

What about certification of PCIe-SSD devices?

PCIe-SSDs are nothing but SSDs with an on-board I/O controller in a PCIe form factor.  Therefore, these require the same level of due diligence as required by standard I/O controllers.  As a result, we are putting these devices through the same level of rigorous certification as we do for I/O controllers.

VMware is working very closely with partners to certify the first set of PCIe-SSDs for Virtual SAN 6.0 over the coming weeks.

 

What are the new updates to the VCG page?

The Virtual SAN VCG page has been enhanced to allow users to easily build or choose their All Flash configurations in addition to Hybrid configurations.  Since All Flash Virtual SAN requires SSDs of different endurance and performance spec for caching and performance tiers (See Updated Virtual SAN Hardware Quick Reference Guide for details on specs), we have enhanced the VCG to help users easily pick SSDs for the tier they are interested in.

We have also introduced a new SSD filter called “Virtual SAN type” to help easily filter our All Flash vs Hybrid configurations.  Furthermore, we have added a filter called “Tier” to help you filter our Virtual SAN hybrid caching, Virtual SAN All Flash caching and Virtual SAN capacity caching tiers.

The endurance rating for SSDs are now displayed on the VCG in TBW (Terabytes written over 5 years) as opposed to DWPD (Drive Writes Per Day) which was used previously.

 

What are the controllers that are currently in the certification queue and when do we expect them to get certified?

Please see the attached list of controllers that are currently undergoing Virtual SAN certification

Note:  In many cases, we rely on our partners to provide driver/firmware fixes for controller issues so if there are delays in receiving these updates from partners, the certification timelines may get pushed out.

Having said that, we are making good progress on most of the controllers listed in the attached document and expect them to follow our standard certification process.

On a similar note, Ready Nodes  are primarily dependent on the controllers getting certified, so as you see new controllers on the VCG for 6.0 certified, Ready Nodes  including those controllers will follow.

Video: Virtual SAN From An Architect’s Perspective

Video: Virtual SAN From An Architect’s Perspective

Have you ever wanted a direct discussion with the people responsible for designing a product?

Recently, Stephen Foskett brought a cadre of technical bloggers to VMware as part of Storage Field Day 7 to discuss Virtual SAN in depth.  Christos Karamanolis (@XtosK), Principle Engineer and Chief Architect for our storage group went deep on VSAN: why it was created, its architectural principles, and why the design decisions were important to customers.

The result is two hours of lively technical discussion — the next best thing to being there.  What works about this session is that the attendees are not shy — they keep peppering Christos with probing questions, which he handles admirably.

The first video segment is from Alberto Farronato, explaining the broader VMware storage strategy.

The second video segment features Christos going long and deep on the thinking behind VSAN.

The third video segment is a run-over of the second.  Christos presents the filesystem implementations, and the implications for snaps and general performance.

Our big thanks to Stephen Foskett for making this event possible, and EMC for sponsoring our session.

 

How To Double Your VSAN Performance

How To Double Your VSAN Performance

VSAN 6.0 is now generally available!

Among many significant improvements, performance has been dramatically improved for both hybrid and newer all-flash configurations.

VSAN is almost infinitely configurable: how many capacity devices, disk groups, cache devices, storage controllers, etc.  Which brings up the question: how do you get the maximum storage performance out of VSAN-based cluster?

Our teams are busy running different performance characterizations, and the results are starting to surface.  The case for performance growth by simply expanding the number of storage-contributing hosts in your cluster has already been well established — performance linearly scales as more hosts are added to the cluster.

Here, we look at the impact of using two disk groups per host vs. the traditional single disk group.  Yes, additional hardware costs more — but what do you get in return?

As you’ll see, these results present a strong case that by simply doubling the number of disk -related resources (e.g. using two storage controllers, each with a caching device and some number of capacity devices), cluster-wide storage performance can be doubled — or more.

Note: just to be clear, two storage controllers are not required to create multiple disk groups with VSAN.  A single controller can support multiple disk groups.  But for this experiment, that is what we tested.

This is a particularly useful finding, as many people unfamiliar with VSAN mistakenly assume that performance might be limited by the host or network.  Not true — at least, based on these results.

For our first result, let’s establish a baseline of what we should expect with a single disk group per host, using a hybrid (mixed flash and disks) VSAN configuration.

Here, each host is running a single VM with IOmeter.  Each VM has 8 VMDKs, and 8 worker tasks driving IO to each VMDK.  The working set is adjusted to fit mostly in available cache, as per VMware recommendations.

More details: each host is using a single S3700 400GB cache device, and 4 10K SAS disk drives. Outstanding IOs (OIOs) are set to provide a reasonable balance between throughput and latency.

VSAN_perf_1

On the left, you can see the results of a 100% random read test using 4KB blocks.  As the cluster size increases from 4 to 64, performance scales linearly, as you’d expect.  Latency stays at a great ~2msec, yielding an average of 60k IOPS per host.  The cluster maxes out at a very substantial ~3.7 million IOPS.

When the mix shifts to random 70% read / 30% writes (the classic OLTP mix), we still see linear scaling of IOPS performance, and a modest increase in latency from ~2.5msec to ~3msec.  VSAN is turning it a very respectable 15.5K IOPS per host.  The cluster maxes out very close to ~1m IOPS.

Again, quite impressive.  Now let’s see what happens when more storage resources are added.

For this experiment, we added an additional controller, cache and set of capacity devices to each host.  And the resulting performance is doubled — or sometimes even greater!

VSAN_perf_2

Note that now we are seeing 116K IOPS per host for the 100% random read case, with a maximum cluster output of a stunning ~7.4 million IOPS.

For the OLTP-like 70% read / 30% write mix, we see a similar result: 31K IOPS per host, and a cluster-wide performance of ~2.2 million IOPS.

For all-flash configurations of VSAN, we see similar results, with one important exception: all-flash configurations are far less sensitive to the working set size.  They deliver predictable performance and latency almost regardless of what you throw at them.  Cache in all-flash VSAN is used to extend the life of write-sensitive capacity devices, and not as a performance booster as is the case with hybrid VSAN configurations.

In this final test, we look at an 8 node VSAN configuration, and progressively increase the working set size to well beyond available cache resources.  Note: these configurations use a storage IO controller for the capacity devices, and a PCI-e cache device which does not require a dedicated storage controller.

On the left, we can see the working set increasing from 100GB to 600GB, using our random 70% read / 30% OLTP mix as before.

Note that IOPS and latency remain largely constant:  ~40K IOPS per node with ~2msec latency.  Pretty good, I’d say.

On the right, we add another disk group (with dedicated controllers) to each node (flash group?) and instead vary the working set size from an initial 100GB to a more breathtaking 1.2TB.  Keep in mind, these very large working set sizes are essentially worst-case stress tests, and not the sort of thing you’d see in a normal environment.

VSAN_perf_3

Initially, performance is as you’d expect: roughly double of the single disk group configuration (~87K IOPS per node, ~2msec latency).  But as the working set size increases (and, correspondingly, pressure on write cache), note that per-node performance declines to ~56K IOPS per node, and latency increases to ~2.4 msec.

What Does It All Mean?

VSAN was designed to be scalable depending on available hardware resources.  For even modest cluster sizes (4 or greater), VSAN delivers substantial levels of storage performance.

With these results, we can clearly see two axes to linear scalability — one as you add more hosts in your cluster, and the other as you add more disk groups in your cluster.

Still on the table (and not discussed here): things like faster caching devices, faster spinning disks, more spinning disks, larger caches, etc.

It’s also important to point out what is not a limiting factor here: compute, memory and network resources – just the IO subsystem which consists of a storage IO controller, a cache device and one or more capacity devices.

The other implication is incredibly convenient scaling of performance as you grow — by either adding more hosts with storage to your cluster, or adding another set of disk groups to your existing hosts.

What I find interesting is that we really haven’t found the upper bounds of VSAN performance yet.  Consider, for example, a host may have as many as FIVE disk groups, vs the two presented here.   The mind boggles …

I look forward to sharing more performance results in the near future!

Upgrading to VMware Virtual SAN 6.0

VSAN-UpgradeVirtual SAN 6.0 introduced new changes to the structural components of its architecture. One of those changes is a new on-disk format which delivers better performance and capability enhancements. One of those new capabilities allows vSphere Admins to perform in-place rolling upgrades from Virtual SAN 5.5 to Virtual SAN 6.0 without introducing any application downtime.

Upgrading an existing Virtual SAN 5.5 cluster to Virtual SAN 6.0 is performed in multiple phases and it requires the re-formating of the of all of the magnetic disks that are being used in a Virtual SAN cluster. The upgrade is defined as a one-time procedure that is performed from RVC command line utility with a single command.

Upgrade Phase I: vSphere Infrastructure Upgrade

This phase of the upgrade is all components are upgraded to the vSphere 6.0 release. All vCenter Servers and ESXi hosts and all infrastructure related components need to be upgraded to version their respective and corresponding 6.0 software release. Any of the vSphere supported procedures for the individual components is supported.

  • Upgrade vCenter Server 5.5 to 6.0 first (Windows or Linux based)
  • Upgrade ESXi hosts from 5.5 to 6.0 (Interactive, Update Manager, Re-install, Scripted Updates, etc)
  • Use Maintenance Mode (Ensure accessibility - recommended for reduced times, Full data migration – not recommended unless necessary

Upgrade Phase II: Virtual SAN 6.0 Disk Format Conversion (DFC)

This phase is where the previous on-disk format (VMFS-L) is replaced on all of the magnetic disk devices with the new on-disk format (VSAN FS). The disk format conversion procedures will reformat the disk groups and upgrade all of the objects to the new version 2. Virtual SAN 6.0 provides supports for both the previous on-disk format of Virtual SAN 5.5 (VMFS-L) as well as its new native on-disk format (VSAN FS).

While both on-disk formats are supported, it is highly recommended to upgrade the Virtual SAN cluster to the new on-disk format in order to take advantage of the performance and new available features. The disk format conversion is performed sequentially performed in a Virtual SAN cluster where the upgrade takes place one disk group per host at a time. The workflow illustrated below is repeated for all disk groups on each host before the process moves onto another host that is a member of the cluster.

VMware Virtual SAN 6.0 Now Generally Available

Virtual SAN 6 – you heard about it in February… thousands of you read about it in Rawlinson’s blog post… and today you can get your hands on it. Virtual SAN 6 is now generally available (GA) – download your evaluation version today! For those of you who missed Rawlinson’s blog post describing the details around what’s new with Virtual SAN 6 – you can read it here (below). But there’s a better way to get the information – register and attend this week’s webinar on “What’s New with Virtual SAN 6” hosted by Rawlinson Rivera – we’ll see you there!

VSAN-ALL-FLASH-LOGO

It is with great pleasure and joy that I like to announce the official launch of VMware Virtual SAN 6.0, one of VMware’s most innovative software-defined storage products and the best hypervisor-converged storage platform for virtual machines. Virtual SAN 6.0 delivers a vast variety of enhancements, new features to the as well as performance and scalability improvements.

Virtual SAN 6.0 introduces support for an all-flash architecture specially designed to provide virtualized applications high performance with predictably low latencies. Now with support for both hybrid and all-flash architectures Virtual SAN 6.0 is ready to meet the performance demands of just about any virtualized application by delivering consistent performance with sub-millisecond latencies.

Hybrid Architecture

  • In the hybrid architecture, server-attached magnetic disks are pooled to create a distributed shared datastore that persists the data. In this type of architecture, you can get up to 40K IOPS per server host.

All-Flash Architecture

In All-Flash architecture, the flash-based caching tier is intelligently used as a write-buffer only while another set of flash devices forms the persistence tier to store data. Since this architecture utilizes only flash devices, it delivers extremely high IOPs of up to 90K per host, with predictable low latencies.

VSAN-Archs

Virtual SAN 6.0 delivers true enterprise-level scale and performance by doubling the scalability of Virtual SAN 5.5 by scaling up to 64 nodes per cluster for both hybrid and all-flash configurations. In addition, Virtual SAN 6.0 improves the number of virtual machines per host up to 200 for both supported architectures.

VSAN-Scale

The performance enhancements delivered in Virtual SAN 6.0 are partially due to the new Virtual SAN on-disk Filesystem (VSAN FS). The new version delivers a new VMDK delta file (vsanSparse) takes advantage of the new on-disk format writing and extended caching capabilities to deliver efficient performance. This results in the delivery of performance-based snapshots, and clone that are comparable to SAN snapshots.

Virtual SAN 6.0 now enables intelligent placement of virtual machine objects across server racks for enhanced application availability even in case of complete rack failures. Virtual SAN Fault Domains provide the ability to group multiple hosts within a cluster to define failure domains to ensure replicas of virtual machines data is spread across the defined failure domains (racks).

VSAN-FD

Along with all the new added features a significant amount of improvements have been added to enhance the management user experience:

  • Disk/Disk Group Evacuation – Introduce ability to evacuate data from individual disk/disk groups before removing a disk/disk group from the Virtual SAN.
  • Disk Serviceability features - easily map the location of magnetic disks and flash devices. Ability light disk LED on failures, Turn disk LED on/off from the vSphere Web Client.
  • Storage Consumption Models - adds functionality to visualize Virtual SAN 6.0 datastore resource utilization when a VM Storage Policy is created or edited.
  • UI Resynchronization Dashboard – the vSphere Web Client UI displays virtual machine objects resynchronization status and remaining bytes to sync.
  • Proactive Rebalance – provides the ability to manually trigger a rebalance operation in order to utilize newly added cluster storage capacity.
  • Health Services – deliver troubleshooting and health reports to vSphere Administrators about Virtual SAN 6.0 subsystems and their dependencies such as cluster, network, data, limits, physical disk.

VSAN-health

With all the major enhancements and features of this release, Virtual SAN is now enterprise-ready, and customers can use it for a broad range of use cases, including business-critical and tier-1 production applications.  Stay tune, there is a lot more to come from the world’s greatest software-defined storage platform.

VMware Virtual SAN Alarms for vCenter Server with PowerCLI

VSANPowerCLIAlarmLogoI was recently involved in a couple customer conversations where the main topics were focused on monitoring and troubleshooting events in vCenter particularly for Virtual SAN.

I know that particular topic has been covered a few times in the past, not only on the VMware corporate storage blog but also by other community blogs. To be more specific, one of the VSAN Champions William Lam has covered this topic extensively on his personal blog.

The work that we have done on the topic of vCenter Server Alarms and Virtual SAN stems from the findings identified in two articles published by William. For more information on what are the recommended vCenter Server Alarms for Virtual SAN and how to add and configure them take a look at the articles listed below:

With vSphere 6.0 and Virtual SAN 6.0 nearing generally available very soon, this script can make things a lot easier for all Virtual SAN customers and provide a simplified way to get all the available vCenter Server alarms for Virtual SAN added and configured within seconds.

I got a chance to work on this little nugget with one of the world’s baddest PowerCLI gurus on the planet and also another VSAN Champion Alan Renouf and William Lam as well whom are members of the VMware virtualization team codename #TheWreckingCrew. Here is a PowerCLI sample code that can be utilized to add and configure all of the vCenter Server Alarms for Virtual SAN. These alarms are applicable to both Virtual SAN versions 5.5 as well as 6.0.

VMware Virtual SAN 6.0: Bootstorm Demonstration

VSAN60-All-FlashSince the official announcement of VMware Virtual SAN All-Flash architecture, most of the conversations have been focused about the solutions incredible performance capabilities and attributes with regards to IOPS, predictable performance, sub-millisecond latencies. All of those attributes are great and part of the reason as to why Virtual SAN 6.0 as a storage platform and its use cases have been expanded to also focus on business critical applications and large enterprise environments.

I want to turn the spotlight onto one of the many supported use cases for Virtual SAN 6.0 and highlight one of the invaluable capabilities of the new platform with regards to Virtual Desktop Infrastructures (VDI).

Some of the functional requirements for large enterprise infrastructure designs for VDI include the characterization of boot, refresh, and provision times for standard operations and worst case scenarios.

I have seen a fair share of VDI designs and demonstrations of different platforms showcasing bootstorms, refresh and rebuilds times they all do a pretty good job. Now with that said I wanted to take the opportunity to showcase the powerful capabilities of the Virtual SAN 6.0 by demonstrating a bootstorm at the maximum supported capabilities of the platform. This bootstorm demonstration consists of 6401 desktops on a Virtual SAN 6.0 All-Flash 64 node cluster (BigDaddy).
The key and impressive items showcased as part of the demonstration are the following:

  • BigDaddy – 64 Node All-Flash Virtual SAN Cluster
  • Desktops – booting all 6401 desktops in the cluster at once (in batches of 1024 at a time)
  • Boot Time – 24 minutes booting all desktops plus allocation of IP address about 19 minutes for a total of about 40 minutes

This demonstration does not contain tampered or custom configurations of any of the Virtual SAN settings. This is what we generally call an Out-of-the-Box experience. Another important thing to point out here is my definition for completed boot time. What I mean by complete boot, is not just when the desktop is powered on, but when all the desktops have successfully acquired an IP address and are really up and running and ready to be use.

In the interest of time, the demonstration has been sped up from its original length of time to about 5 minutes. Feel free to pay attention to the timestamp as it is displayed in the command line interface to validate the accuracy of the booting time.

This demonstration successfully highlights the one of the many powerful capabilities of available in VMware Virtual SAN 6.0.
