 I'm looking for feedback on two items :

1. Experience with GFS  using  iSCSI 
2. Any experience using the HP 2012i iSCSI array .

My current application runs  AS 3 with clustering on a 2 node HP DL380G3 
Packaged Cluster(SCSI shared array) in a primary/secondary configuration. 
The data is made available to other  local ES3 machines(4 x DL380G3/4's) 
via NFS. 
These machines run reports as well as run apache for user access.  The
shared array holds numerous log files which are written to constantly. 
Currently we have ~200 files which recieve ~4GB of data daily so the write
 loading is not high. 

One option for upgrading is to : 
 - Upgrade to latest RH with clustering and GFS on all the servers.
 - Have the shared data on a HP iSCSI(MSA2012i) which is 
   accessed by all. We use HP equipment so my options are limited.

I have found the following article comparing iSCSI devices including
 HP2012i on both Windows and Centos 5  : 
HP 2012i results :
