Synology in the Homelab – NFS 3 vs 4.1

Recently, I purchased a Synology 1817+ to be used as storage for my homelab. Previously, I was using an older, and much slower Synology, RS812, as well as a running vSAN on my single host. While vSAN performance was great, I ran into multiple issues trying to run on a single host, with FTT=0 and Force Provisioning set to On. Cloning, Restores, etc would fail due to trying to use it in an unsupported manner. So, enter the Synology 1817+! iSCSI or NFS? When I got the NAS online, I[…]

All Your Protocols Are Belong To Us

In the storage wars, we typically hear about block vs file, iSCSI vs Fibre Channel, SAN vs NAS, and so on.  The truth is, none of that really matters; at least, not as much as some make it out to. What’s really important, as with most IT decisions, is using solutions that allow the business the ability to consume, transform, and utilize its data as effectively and efficiently as possible.  While there are many different ways to allow the business to do so, I Want to focus on the different storage[…]

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[…]
