ESXi 4.1 with ARECA Raid controller

[AgentJay]

Hello,

I've got an areca 1200 raid card too... and 16x2Tb Hard drives in RAID 6 I also have a 32Gb SSD with ESXi 4.1 installed on it, and a VM with Ubuntu server. I've had to install the areca raid driver to allow the detection of the card, but trying to add the HD array as a datastore gives me the error:

Call "HostDatastoreSystem.QueryVmfsDatastoreCreateOptions" for object "ha-datastoresystem" on ESXi "my server IP" failed.

Welcome to the Community,

the size of a LUN for ESX(i) is currently limited to 2TB minus 512 Bytes, due to the iSCSI-2 limitation. You need to create logical drives on your array with this size (or smaller).

PS: I branched your question to its own topic. Instead of asking questions on an already answered thread, you should always open your own questions to get the attention you expect.

There is no benefit to installing ESXi on the SSD drive other than a faster startup. ESXi loads directly into RAM and does very little writing to disk other than an hourly configuration backup. You might have a look here
