Server 2012 - Hyper-V-Cluster - Shared SAS - StorageSpaces

hi,

i want configure hyper-v-cluster server2012. storage want have combination of shared sas  (jbod dual expander + hba) , new storagespaces-feature.

in szenario have configure storagespaces csv make shure that all cluster-nodes have access storage ("clustered storagespaces"), correct?

now read thin-provisioning , parity-spaces not supported in such clustered environment. lose two important features. correct, too??

regards

christian

please use these step-by-step guides on how configure clustered storage spaces:

yes, mirrored content supported (but you'll need more actual spindles have *clustered* mirror plain 1 - beware!). 

there rumors ms support parity next version need fix not great partity performance before putting cluster. see:

also speaking it's bad idea put vms on raid5 (or raid6) unless know sure volume of reads , few writes. see:

http://blogs.technet.com/b/mspfe/archive/2013/02/25/why-windows-server-2012-parity-storage-spaces-might-perform-slowly.aspx

“the caveat of parity space low write performance compared of simple or mirrored storage space, since existing data , parity information must read , processed before new write can occur. parity spaces excellent choice workloads exclusively read-based, highly sequential, , require resiliency, or workloads write data in large sequential append blocks (such bulk backups).”

also there's possibility achieve same results w/o spending money on sas controllers, sas spindles , sas enclosures , utilizing only

commodity of shelf hardware. see:

hope helped :)
