All,
Continuing my OF research, are there any known limittations with
volme sizes or physical disk sizes/numbers? We are reviewing a system
with 16 500GB sata drives, a 3ware 9650E controller card
http://www.3ware.com/products/pdf/9650SE_DS_101106.pdf , and a dual
opteron 270 system with 2gig of memory tyan s2892 MB. I intend on
striping 10 of these drives with raid 10 for VMware and the other 6
with raid 6 for disk to disk backups, which sould provide around 2.5TB
of storage for use in vmware and 2.5TB for disk to disk backups. I
have read that the card will present 1 2tb disk and one 500GB disk to
the OS in this situation where a single device is over 2TB,
IIRC with the newer cards, this is actually tunable. So you could for
instance just do 4 x 1250 and recombine in OF using the volume manager.
and then I will chop those up into some smaller volumes as needed.
Anyone have experience with a similar set up, any known issues with
the raid card or MB and OF, also any limitations I may hit with the
amount of storage I am looking at?
ext3 max on x86_64 == 16TB
xfs max on x86_64 == more_storage_than_you_can_fit_in_the_box>TB ;)
