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!!!!

With VMworld being a few days way, the amount of excitement is palpable. The number of amazing announcements, news, and events that will take place during the week of August 24th is going to be awesome.

The Software-Defined Storage and Business Continuity teams want to make sure everyone attending the conference is precisely aware of all events, sessions, group discussions, and Hands-On-Labs that will be available during the week. We have put together a guide that can be easily accessed through our blog as well as a Software Defined Storage and Business Continuity Guide pdf version to bring along for easy access.

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 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!!!!

VSAN-VDIIt’s time for everyone to get up to speed with the latest and greatest VMware Virtual SAN Design and Sizing guidance for Horizon View Virtual Desktop Infrastructures. In this new white paper, Wade Holmes and I leveraged the previously provided guidance from the VMware Virtual SAN Design and Sizing white paper, and applied it to the Horizon View Virtual Desktop Infrastructures use case.

This new paper provides prescriptive guidance for sizing and designing of all key requirements and components of Horizon View Virtual Desktop Infrastructures for VMware Virtual SAN. Some of the specifics items are listed below:

  • System Sizing and Desktop Classification
  • Host Sizing Considerations
  • Host CPU Sizing
  • Host Memory Sizing
  • CPU Sizing Assessment
  • Resource Overhead
  • Object calculations for Horizon View Desktops
  • Disk Group Sizing
  • Magnetic Disk Sizing
  • Flash Capacity Sizing

We highly recommend reviewing the white paper as inadequate sizing can a negative impact on the overall performance of Virtual Desktop Infrastructure. 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:

Since 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:
