VMware Virtual SAN Sizing Tool

Oh yeah!!!!!! It’s official, the Virtual SAN Sizing Tool is now live and available to the general public.

All Virtual SAN customers and enthusiasts can easy get sizing ideas and estimations on the amount hardware resources necessary to support a particular Virtual SAN design. All you will need  to do is provide a few virtual machine inputs based on capacity, performance, and availability requirements.


VMware Virtual SAN Sizing Tool

The purpose of this tool is to help determine the hardware specifications for hosts in a Virtual SAN cluster required to run a set of virtual machines defined by a set of input characteristics. These important assumptions should be understood before using this tool:

  • All hosts in the cluster are assumed to have an identical hardware profile, i.e. numbers of hard drives and flash devices, amount of physical RAM, and number of CPU cores
  • All virtual machines are assumed to be identical in storage characteristics, i.e. number of VMDKs, size of VMDKs (assumed identical for all disks), number of snapshots, and virtual memory size
  • All virtual machines are assumed to have the same Virtual SAN policy, i.e. number of failures to tolerate and number of disk stripes per object

The tool is designed so that you can easily vary inputs to see the impact on the sizing output, thus allowing you to iterate manually for more sophisticated analyses.

Feel free to provide feedback and let us know what your thoughts are about the tool and help us improve it.

See you all at VMworld!!!!

Monitoring VMware Virtual SAN with Virtual SAN Observer White Paper

Virtual SAN ObserverAs customers continue to implement VMware Virtual SAN in their environments, it is critical for them to have the ability to properly monitor and troubleshoot the performance of the system. Having access to the adequate tools and knowing how to use them and knowing how to interpret the data being presented is crucial for all customers.

This new paper Monitoring VMware Virtual SAN with Virtual SAN Observer focuses on the Virtual SAN Observer tool, and it is intended to provide Virtual SAN customers with more than just a how-to experience. It also helps to understand the data output and values presented by the Virtual SAN Observer when monitoring and troubleshooting their VMware Virtual SAN implementations.  This paper is a special release because it coincides with a hands-on lab being presented at VMworld this year that will give customers access to a first hand learning experience.

While at VMworld look for the VMware HOL lab listed below:

ELW-SDC-1408 – VMware Virtual Storage Workshop

This Expert Led Workshop focused on VMware Virtual SAN, participants will gain hands-on experience deploying, configuring and managing VMware’s latest hypervisor-converged storage solution.  In this Workshop, you will have access to the Product Experts and is your opportunity to ask questions relevant to your environment.  The Self-Paced version of this lab, SPL-SDC-1408, will available anytime the Hands-on Labs are open.

See you all at VMworld!!!!

Profiling OLTP performance on Virtualized SQL 2014 with All Flash Arrays

TPC-C Benchmark is an on-line transaction processing (OLTP). (TPCC Main site) TPC-C uses a mix of five concurrent transactions of different types and complexity. The database is comprised of nine types of tables with a wide range of record and population sizes. TPC-C is measured as transactions per minute (TPM).

The goal of this exercise was to see if 1 million TPM can be achieved on virtualized SQL 2014 backed by an all Flash storage array for a TPC-C like test.  The TPC-C testing would be compared between two VM sizes (Within NUMA & Exceeding NUMA boundaries)

Understanding Data Locality in VMware Virtual SAN

VMware Virtual SAN LogoSince the release of VMware Virtual SAN, I’ve been involved in numerous costumer and field conversations around the topic VMware Virtual SAN’s ability to take advantage of data locality.

I have addressed the question in several of the Virtual SAN presentations I have delivered, but I realized that this was an ongoing topic of discussion and one which we needed to provide more details in order to satisfy everyone that has been wondering about this topic.  I figured it was time to put together some form of OFFICIAL collateral providing in-depth  details around this topic.

So, like any storage system, VMware Virtual SAN makes use of data locality. Virtual SAN uses a combination of algorithms that take advantage of both temporal and spatial locality of reference to populate the flash-based read caches across a cluster and provide high performance from available flash resources.

For more details on this topic, download the new Understanding Data Locality in VMware Virtual SAN white paper from the link below:

Thick vs Thin Disks and All Flash Arrays

Thin vs Lazy Thick vs Eager Thick disk performing profiling on all flash arrays:

Which type of disk is better?

There has always been an ongoing debate on whether thin or thick disks are best suited for high performance IO workloads. While Eager Zeroed Thick disks provide the best performance, they occupy the entire space including unused space in the overlaid file system and are hence not efficient with space utilization. Thin disks consume only the space used by the overlaid operating system or application but have underlying performance concerns for high IO workloads.

Having requirements such as eager zeroed thick for high IO workloads made the job of both the virtual and storage admins difficult. There is extra effort and coordination required to deviate from the norm of using thin disks for traditional virtual machines  and to separate out the LUNS with special formatting. These  special requirements were operationally hard to implement and maintain.

Flash storage has revolutionized and improved its performance many fold. All flash storage arrays holds the promise of greatly improved performance. Can use of All Flash arrays obviate the need for different storage LUNS and formatting for high IO workloads?

Automating Failover with SRM and PowerCLI

Today we’ll take a look at running a recovery plan for SRM programatically, from the API via PowerCLI.

In almost all scenarios, falling over in an automated fashion is a poor idea.  There is a lot of risk associated with it and a lot of potential liability for failing over due to incorrect reasoning.  Failing over automatically in *test mode* however makes an awful lot of sense!

vSphere Data Protection Advanced Automated Backup Verification

The best way to verify backup data integrity is to routinely perform restores from this backup data. For a variety of reasons, the majority of administrators do not verify backups using this method very often (if ever). Wouldn’t it be great if a backup and recovery solution provided the option to do this automatically on a regular schedule? Wouldn’t it be even better if the solution reported the results of the verification exercise? I am happy to report that is one of the new features of vSphere Data Protection (VDP) Advanced 5.5! Keep reading for more information and to download a short white paper on the topic that includes best practices…
