DSS V6 Lite / XenServer 5.6 / ~20 VMs advice please.
Awesome! Now that XenServer is Certified with DSS V6, how about some advice while I'm using DSS lite?Originally Posted by To-M
I just installed DSS V6 using block mode IO iSCSI on this system:
3ware 9690SA-8I-SGL RAID card 512MB DDR3 onboard
SUPERMICRO MBD-X8DTE-F-O
2 x Kingston SSDNow S100 SS100S2/8G 2.5" 8GB SATA II (RAID 1 - system)
4 x Western Digital RE4 WD5003ABYX 500GB 7200 RPM SATA (RAID 10 - storage)
1 x Intel Xeon E5506 Nehalem-EP 2.13GHz
1 x Kingston 4GB 240-Pin DDR3 SDRAM DDR3 1333 ECC Registered
Onboard NIC (for management)
4 x Intel 82571EB Gigabit Controllers (802.3ad bonded - for iSCSI)
These VMs are spread out amongst 3 Servers with 2 Gigabits of bonded 802.3ad traffic available to each. Very bursty traffic (web servers, DNS, RADIUS, network monitor, and similar). Moderate amount of traffic at best. I would say the total average is only 150 MB/sec during peak for a few minutes. I would like to optimize everything for as low latency as possible.
How's this build above look for hosting the storage for all these machines? Any thing I need to worry about? Should I pop in more memory to help with read/write performance?
Just a note, I am VERY excited to try out the MIRROR feature in the full version, but I want to get a grasp on the basics first in the LITE version! I've spent a lot of time with other iSCSI / NAS / SAN configs using both windows and Linux based builds from scratch and from other storage specific distros. This looks like a better alternative for us than the others.
