NAS with iSCSI for vSphere


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 …

  1. Just ordered a Readynas NVX for my homelab, was also looking at Iomega storcentre, but opted for the better performing netgear.
    Promo on also with x2 drives for the 500GB model, will benchmark and see how it compares with others.
