Hi All,
Need some information on getting the right storage array to buy for my
cluster configuration can anyone help me with this
my Setup so far
2 Athlon 2800 Sempron System
1 Wti Network power switch
1 24 Port 10/100 Cat5 switch
2 Adaptec 39160 scsi host adapter pci cards installed in the systems.
I need to know what is the best storage solution with this configuration
Thanks

Yes, I would like to have a shared storage setup, the question is can I do it from the scsi cards I have & if so what other equipment I need to have this setup. Thanks Sherwyn Greene Planner / I.T.

We are using a 3.0 Terabyte Iscsi-enabled SAN device made by Promise... Works really well on Centos. For what people go through with HP and other vendors, this was very much worth it, very little hassle and no vendor lock-in. We connect our servers to GB switches, GB Nics, Cat 6 cable (very important about Cat6 and Iscsi) and they talk to the promiseraid over Iscsi and are mounted to it in filesystem. The promiseraid itself just sits on the rack plugged into a GB switch itself, everyone's happy. A great reliable affordable simple way to add storage in a clustered environ, in this case out clustered app is of the Javagroups/Tomcat/Apache ilk, along with quite a bit of Mysql. We backup our mysql boxes to the Iscsi device quite well, some of which are 100+GB tables. So you need a GB switch and some cat6 going on and you are very much OK then if you get an Iscsi solution. -krb> On Tue, 2006-10-17 at 09:14 -0400, Sherwyn Greene wrote: >> Hi All, >> >> Need some information on getting the right storage array to buy >> for my cluster configuration can anyone help me with this >> >> my Setup so far >> >> 2 Athlon 2800 Sempron System >> 1 Wti Network power switch >> 1 24 Port 10/100 Cat5 switch >> 2 Adaptec 39160 scsi host adapter pci cards installed in the systems. >> >> I need to know what is the best storage solution with this >> configuration > > It depends of what you want to do ... which kind of cluster do you want > to implement ? a linux-ha type cluster based on heartbeat ? > Do you need a shared storage ? in that case a san in fiber-channel or > iscsi should work.
