Take the plunge into HCI – Run a simple vSAN Assessment!

Are you experiencing challenges with your current vSphere storage environment (i.e., performance, capacity constraint, complexity, expensive renewals) or just not sure if VMware Virtual SAN (VSAN) would be a good fit?

Now VMware partners, SEs, or reps can help you with a free VSAN Assessment.

In just 1 week (recommended min), they can use VMware VSAN Assessment tool to collect and analyze data from customer’s vSphere storage environment (i.e., I/O patterns), and provide following technical and business recommendations:

  • Which VMs are a suitable candidate for Virtual SAN – Hybrid or All Flash
  • Sizing and hardware recommendations (i.e., number of servers, SSD, HDD)
  • TCO analysis compared to storage arrays

Sample Outputs of VSAN Assessment

The tool can analyze the VMs for VSAN All-Flash or Hybrid

The tool also looks at the CAPEX and OPEX, and compares VSAN’s TCO with other storage arrays.

How difficult is it to deploy the tool?

It is a fairly straightforward process. Once customer gets the invitation from VMware partners to participate in the assessment, it takes minutes to download the Collector Appliance (OVA) and then another 15-30min to configure depending on size of cluster that customer wants to be assessed.  The tool then goes into data collection mode in a non-disruptive way.

Is the tool collecting sensitive customer data?

No, the VSAN Assessment tool does NOT collect or store any content or customer data. The tool only collects vscsi traces to analyze I/O patterns of the workloads running on vSphere. For every I/O, all that the vscsi trace collects is information about the content and NOT the content itself, which include the following:

  1. Whether the I/O is a read or a write
  2. LBA (Logical Block Address)
  3. Number of bytes
  4. I/O Size
