Why VSAN All-Flash is the right choice

  VMware’s HCI (Hyper-Converged Infrastructure) solution is VSAN – or Virtual SAN.  It’s a kernel based solution built right into the ESXi Hypervisor, that allows each server to consume local storage, and pool it together and share it back out to the VMware cluster.  A minimum of 2 hosts is required (plus another witness appliance) or simply 3 or more hosts to maintain quorum.  4 hosts are typically recommended, in order to maintain availability when 1 host is in maintenance mode or offline. Local disks in each host are combined into[…]

VSAN Storage Profile Missing

  Recently, I was moving my lab away from the VSAN beta code, and onto the ESXi 5.5 update 1 bits.  I started fresh with my hosts, and simply upgraded my vCenter server.  However, I ran into an issue once I had enabled VSAN.  I had no storage profiles. If I clicked on refresh, it came back with the error : “there was a problem encountered while resyncing the VSAN providers”   Apparently, this is not an issue for new vCenter installs, and only seems to be affecting those who[…]

VSAN – Installation

Installation of VMware’s Virtual SAN (VSAN) couldn’t be easier. No, really! To start with, in my lab environment, I have 4 servers that will participate in the VSAN cluster, and 3 of which will provide storage resources to the VSAN cluster. 3x DL160 G6 with: 128GB SSD 3x 250GB SATA drives (or larger) 1x DL360 G6 At this point, I have already added all 4 servers into a cluster with HA off. Step 1: Enable the VSAN service on a VMKernel port. Create your virtual switches, and create at least 1[…]

VSAN – Overview

This is part 1 in a new series covering VMware VSAN. Stay tuned for more! VMware VSAN (Virtual SAN) is a new storage offering from VMware, not to be confused with the VMware VSA (Virtual Storage Appliance), which serves a different purpose entirely.   VSAN is a scale out storage solution that utilizes the local storage of the ESXi hosts, and presents a single datastore to the cluster.  Driven by Storage Profiles, the options for VM performance and redundancy are on a per VM basis. What VSAN consists of: ESXi[…]

Running Nested ESXi 5.5 on VSAN

  With vSphere 5.5 now out, it was time to refresh my lab.  I have ESXi 5.5 installed on a DL160 G6, with 1 SSD and 3 SATA drives, so I decided to make a single node VSAN instance. (3 nodes is a minimum for a supported configuration). The plan was to spin up some nested ESXi instances, like my usual lab setups, but I ran into a problem.  I could not get ESXi 5.5 to install – it kept failing.  Here is what I was receiving: This program has[…]
