Needed to buy a shared storage for a small vSphere 4.0 sandbox – here are my observations.
- Was looking for block storage device – so that I can use vmfs. Barring that, I was Ok with NFS
- We already have netApp et al in our concept lab. So wanted a low budget solution that will hold 2 to 4 ST31000340NS (Seagate 1TB, SATA Barracuda) disks
- iSCSI looked like the best option for block storage
- After some digging around, the choice was between NetGear ReadyNas, Synology 209 and the QNAP 210
- Lower end NetGear boxes don’t support iSCSI
- Both Synology and QNAP are based on Marvell 6281 chip and with 256MB memory (BTW, check out the plug computer which also is based on the 6281 ! Very interesting … A topic for another day …)
- Synology has the 209j and the 209+II. The 209j is way under powered and the 209+II has better CPU and more memory, but prices a little high
- Both SY209 and the QNAP210 have iSCSI target interface but looks like the QNAP is more advanced. (Quite possible that both are based on the Linux iSCSI substrate !
- So finally I ordered 2 of the QNAP 210s
- BTW, an interesting contender is the Windows Storage Server with iSCSI ! Adding the iSCSI control plane to Win2K8R2 is a brilliant move by Microsoft !
- I will blog the agonies and ecstasies after setting these up in my vSphere 4.0 sandbox …
