One of the interesting characteristics of Virtual SAN is that fact that it gives customers and partners the flexibility to define a storage solution through either building your own node via components on our VMware Compatibility Guide for Virtual SAN, or selecting a predefined Virtual SAN Ready platform. These predefined Virtual SAN hardware platforms are known as Virtual SAN Ready Node and Ready Block.
As mentioned in this previous post, we will have a number of Ready Node and Ready Block configurations being announced over the next month from multiple vendors.
So what exactly is a Virtual SAN Ready Node or Ready Block?
A Virtual SAN Ready Node is a single pre-configured server while a Ready Block is a pre-configured set of servers for use with VMware® Virtual SAN™. Configurations are based on HDD, Flash and IO Controller components certified for Virtual SAN on the VMware Compatibility Guide, combined with servers certified on the VMware Compatibility Guide.
Ready Nodes and Ready Blocks will be categorized into configuration profiles to target specific use cases in a Ready Node Recommended Configuration List. Predefined Ready Node or Ready Block profile categories include:
Performance – Suitable for high performance use cases
Balanced – Suitable for use cases requiring a blend of performance and capacity
Capacity – Suitable for high capacity use cases
Entry – Suitable for ROBO use cases
Each category allows for differentiated price/performance offerings targeting different use case requirements. For each of these profiles, we specify a target number of VMs per node utilizing an average VM size (as indicated alongside the configuration), a default failures to tolerate = 1 policy, and approximately 30 percent free storage capacity for future growth.
The details of these specific Virtual SAN Ready configurations will be released on the VMware Compatibility Guide landing page over the next few days. So get ready for Virtual SAN Ready Node and Ready Block!
Now that we have officially launched Virtual SAN, its time for everyone to get up to speed with the some of the latest and greatest changes with regards to the new design and sizing considerations guidance for Virtual SAN.
Yesterday, we announced the official release time frame for the general availability of the product the week of March 10th as well as the items listed below:
3 to 32 node cluster support
Maximum support of 3200 Virtual Machines
2 Million IOPS performance capability
4.4 Petabytes of Storage Capacity
Along with those changes and updates there are also some significant changes in the recommendation for the sizing of the flash layer for Virtual SAN. I highly recommend reviewing the white paper as the new sizing guidelines can have an impact on the overall investment and performance of the flash layer for Virtual SAN. The new design and sizing guide can be found and downloaded from the VMware Virtual SAN product page or directly from the link provided below:
VMware is excited to collaborate with Fusion-io, a leader in flash solutions with deployments by more than 6,000 customers, to provide customers a range of 15 enterprise-class PCI-E SSDs certified for Virtual SAN™ (see the VSAN Compatibility Guide). Virtual SAN™ leverages the speed and power of server-side flash to deliver a high-performance cache in front of direct-attached disks to provide scalable and cost-effective shared storage solutions.
SanDisk is actively supporting VMware in our Virtual SAN™ launch, providing high-performing, high-endurance flash drives that enable enterprise-class scalability while minimizing IO storage latency for read and write operations.
The Virtual SAN team has been running a public beta program for the past six months with more than 12,000 people registering online. We have received a lot of feedback during that period and wanted to share with you the experience of a few of them.
This is the first post of a series of customers talking about their experience with Virtual SAN.
The VMware Mobile Knowledge Portal iOS and Android app has recently been updated. It sports a great new look and feel and makes finding the information you need even easier by grouping it by area in our SDDC vision.
With the upcoming release of Virtual SAN, I want to take the opportunity to demonstrate some of the interoperability capabilities of Virtual SAN with other products and solutions.
I will start the series by showcasing Virtual SAN’s interoperability with OpenStack. This demonstration is based on the vSphere OpenStack Virtual Appliance (VOVA) and Virtual SAN. This demonstration showcases the integration capabilities between a VMware Virtual SAN and the OpenStack framework by deploying a single instance of vSphere OpenStack Virtual Appliance (VOVA) as the OpenStack cloud controller onto a Virtual SAN enabled vSphere 5.5 Cluster and deploying OpenStack based virtual machines or instances onto the Virtual SAN shared and distributed storage resource.
OpenStack environment running on vSphere can take advantage of the only hypervisor-converged solution in the industry and leverage the simplified management, operational model and technologies:
Hybrid disk solution – flash based devices (SSD) and magnetic disks (HDD).
High performance and distributed RAID architecture.
Built-in application availability (if required for legacy applications).
Storage Policy Based Management framework.
Dynamic storage scalable capabilities (scale up and scale out).
Virtual SAN can also be considered in the context of quality of service (QoS) because VM Storage Policies can be use to define the level of performance, availability, and capacity required on a per–virtual machine or instance basis.
You have probably heard the terms “Big Data” and “Hadoop” mentioned somewhere in the industry lately – they are both very popular subjects of discussion at the moment. This blog gives you an introduction to the core technology and explains some of the contributions that VMware continues to make to the Hadoop world.
