Hello,
I am new to ESXi, recently I setup new server ESXi 5.1, my hardware conf. is:
MB: Intel DQ77MK (2x 1Gb NIC)
i5-3470T
32 Gb RAM
1Gb NIC (intel 82574L)
1Gb NIC (intel 82574L) - VMKernel Port for iSCSI (different LAN)
local SATA 320 Gb for shared vmfs disk
local SATA 74 Gb WD raptor for VMs swap
today I just bought 60 gb SSD - planing to use it for: host swapping to a SSD - dont know how much would speed up VM itself is one runing from local SSD - compare to iSCSI?
Otherwise for VMs iSCSI disk on Synology NAS DS1511+ (Thin Provisioning & VMware VAAI support)
My iSCSI was created on Volume (created by NAS), I read somewhere, that is perfromance difference if you first create iSCSI (before any Volume is created).
So I am planing (after all backup of NAS) to create first iSCSI LUN, than go with volume.
My question is:
is it better to create (for performance):
a) 1 iSCSI LUN + iSCSI target on it, for each VM - (if you have them 10 = 10 iSCSI LUNs + 10 iSCSI targets)
b) 1 iSCSI LUN + multiple iSCSI targets on it for multiple VMs
Any other suggestion is welcome.
