Hi guys,
right now i am looking in converting my SAN Setup (see below) to DAS Setup for my 2-Hosts VMware-Cluster.
The Specs of the SAN right now:
Chassis: Intertech 4U 20bay
CPU: Intel Xeon E5-1630 V3 (4x 3,7Ghz + HT)
Mainboard: Supermicro X10SRH-CLN4F
RAM: 2x 32GB Samsung DDR4-2133 (64GB)
Networking: 2x Intel X520-DA2
Software: FREENAS 11
Disks:
8x 5TB WD RED in Mirrored vDevs (aka RAID10)
6x 480GB Samsung PM863a in mirrored vDevs (aka RAID10)
1x SSD internal for OS
VMware Cluster:
2x HP DL380p G8 each with:
CPU: 2x E5-2690 v2
RAM: 256GB DRR3
Networking: 10Gbit 2-Port SFP+
no harddrives, enough room for HBAs
The setup is running fine right now, but i notice weak IO Performance of my vms on the iSCSI volumes, even when the SSDs are only 10-20% busy.
The Reason why im not going with the storage in the VMware hosts and using vSAN is the licensing costs.
I am running about 40 vms on the cluster, from AD, Exchange, minor My- and MSSQL Databases to some game and testing ones.
Due to network latency the maximum IOPS should be about 4000 (1sec/0.25ms) if requesting QD1, but i cant tell if thats the bottleneck to pull the vms down that much.
All in all im reaching out to you now and hopefully get some hints if its a good idea to replace my SAN with a DAS solution like an HP D2600 or similar.
If you need any further information... no problem!
