Hi,
I'm looking to build a virtualized web hosting server environment
accessing files on a hybrid storage SAN. I was looking at using the
Sun X-Fire x4540 with the following configuration:
* 6 RAID-Z vdevs with one hot spare each (all 500GB 7200RPM SATA
drives)
* 2 Intel X-25 32GB SSD's as a mirrored ZIL
* 4 Intel X-25 64GB SSD's as the L2ARC.
* De-duplification
* LZJB compression
The clients will be Apache web hosts serving hundreds of domains.
I have the following questions:
* Should I use NFS with all five VM's accessing the exports, or
one LUN for each VM, accessed over iSCSI?
* Are the FSYNC speed issues with NFS resolved?
* Should I go with fiber channel, or will the 4 built-in 1Gbe
NIC's give me enough speed?
* How many SSD's should I use for the ZIL and L2ARC?
* What pool structure should I use?
I know these questions are slightly vague, but any input would be
greatly appreciated.
Thanks!
Which Virtual Machine technology are you going to use?
VirtualBox
VMWare
Xen
Solaris Zones
Somethinge else...
It will make a difference as to my recommendation (or, do you want me to
recommend a VM type, too?)
<grin>
