setting up dedicated NAS for ESX 4.x datastore Best practice
Posted on 2010-11-19
Hi fellow experts,
As long as I'm here I thought I might post a question as well.
We recently freed up one of out NAS devices, which I'm planning to use as a dedicated data store for our ESX (4.1) cluster, three servers at the moment.
What have I got:
A eurostor E-8700 which contains an Areca ARC-1261(firmware V1.42 2006-10-13) with 16 Samsung HD103SJ 1T disks, Motherboard is a Supermicro x7DB8 (BIOS R2.1a) with 2GB RAM and some dualcore Xeon (not sure which).
4 GB nics (2x Intel 80003ES2LAN Gigabit Ethernet Controller & Intel Corporation PRO/1000 PT Dual Port Server Adapter), going to bond them to one interface.
The device is running open-e DSS Model: Data Storage Server Version: 5.0.DB49000000.3278 (still have to upgrade to the latest version).
The ESX servers will each have 2 nic's connected to the storage network. The servers and the NAS will be on a separate switch, a Cisco Catalyst WS-C3560G-48TS-S with no other devices attached to it. Mayby later on I will add my ESX test cluster to it (also 3 servers).
What I would like you to share with me is the best practice to set this thing up as a dedicated NAS for my esx farm.
Two things I will do: use RAID6 with two hot spares and use NFS.
For the rest, tell me what you think is the best way, beginning with creating the volume(s) (volume size, stripe size, cache mode, etc) all the way through to connecting it to the network and the ESX machines (jumbo frames,etherchanneling, etc).
What do you think is the best way, what is recommended, what are your own experiences, any documents?
Let me know & share you knowledge :)
