Storage server for vmware

I have to buy a storage server for a vmware cluster.
The budget is about $20K.

We already have an EMC Isilon as main storage, so this will be just in case of any problem with the isilon.

The usable space should be at least 10TB, with 10K rpm drives in RAID10 (no raid5-6 etc.)

ideas?
 
If you have a good SuperMicro system house around and some knowledge or interest in Unix/ ZFS,
you may order a similar config as I currently use/order

- Supermicro case 24 x 2,5"
http://www.supermicro.nl/products/chassis/2U/216/SC216A-R900LP.cfm

- SuperMicro Mainboard (10 GbE, SAS 2308 flashed to IT mode)
http://www.supermicro.com/products/motherboard/Xeon/C600/X9SRH-7TF.cfm
6x Onboard SAS + 2 x Onboard Sata (bootdisk) connected to the backplane via reverse breakout cables

- add a 4 or 6 Core Xeon with 64GB ECC RAM (use max 128 GB)

- 2 x LSI 9207-8i (LSI 2308, IT mode per default)

- 2 small SSD as boot mirror

- 10 x Sandisk Extreme PRO SSD 960 GB in a Raid Z2 (7,6 TB usable)
http://www.storagereview.com/sandisk_extreme_pro_ssd_review

- add 10 x Sandisk Extreme PRO SSD 960 in a Raid Z2 (15,3 TB usable, gives up to 10000 IO/s under load)
(with SSD you do not need mirrors as a single SSD has initially about 90000 IO/s and up to 5000 IO/s under load compared to a disk with about 100 IO/s)

- one SSD as a hotspare
- optionally one Intel S3700 SSD (100GB or 200 GB) as an additional write optimized logdevice to reduce small writes on the main pool

- OmniOS ZFS filer, used as NFS storage (or SMB, iSCSI, free)

My recommendation is to look at HP StoreVirtual VSA. Do you have spare storage capacity or have JBODs you can leverage? If so, StoreVirtual VSA takes that capacity and presents it to your VMs as a virtual SAN.

There's a free 60 day trial you can download at http://www.hp.com/to/TryVSA and you can read more about it at http://www.hp.com/go/VSA

Click to expand...

What is your useage profile? Any reason why you need spinning disks instead of SSD? What type of network will your ESXi cluster be using to access the fileserver. Explain your reasoning for mirrors (there are plenty of good reasons to go with mirrors, IOPS is not one of them anymore). What is your desired level of redundancy for storage (do you want to survive server failure and keep running, or do you just need disk & network redundancy)?
 
Nimble storage, check them out, forget about EMC and Netapp and home built, the performance you get could probably take over for your EMC box and use it as a backup instead.
