Can anyone offer some input or possibly give an answer to this.  I need an entry level storage solution for a simple 2 node cluster.  I have a compaq storageworks 4314r
http://h20000.www2.hp.com/bc/docs/support/UCR/SupportManual/TPM_148451-002/TPM_148451-002.pdf

That is a link to a similar product.  It supports a single or dual scsi module.  Can that be used to connect to two servers to create the cluster?  Or will I need somethign different, I have used EMC AX100 or AX150 for clustering, but need something cheaper for this project.  What I am confused about with the compaq unit is that with the dual scsi module it splits half the disks onto each scsi bus, that doesn't seem to make sense to work for a cluster.  Either way make a suggestion to a cheaper solution or help me understand the operation of the compaq unit.

Thanks much.

No. The dual SCSI module splits the bus into two so that half the disks are on one bus and half on the other. You can however use it as a disk enclosure on a MSA1500cs for fibrechannel cluster or a MSA1510 for iSCSI cluster.  It will also hang off a MSA500 for SCSI cluster but since that has 14 internal bays anyway it's probably not worth it.

Should be fine, we have used the Compaq 4100 storage shelf with a EL8 fibre hub and two Compaq HBA's.
I would think as long as both nodes can see the disk, it should be good.  Ensure the SCSI ID is different on each node.  The dual bus will not work for the cluster as it splits the bus into two.

What type of controller is in the 4300?

They don't have controllers, it is the fore-runner of the MSA30, i.e. just an enclosure.

Dis-regard my comments I was review the wrong storage shelf.

Thanks all.  What other solutions are there that will work out of the box similar to EMC AX100 or AX150?  I have found some but they are too pricey, anything less expensive?  This doesn't need to be terrbily robust, just disks for a cluster, not high traffic or high disk writes / reads.

Does anyone know if a IBM EXP300 Storage Array would work for clustering.  It has two SCSI adapters, not sure how the drives would be split, does anyone know the configuration of the device, I couldnt find much that either proves or disproves that it would work with clustering.

Don't think so.
If it's price rather than performance you can use a SATA/iSCSI system, A12E-G2121-2 from infortrend is only $4500 without disks for example. Or HP's AiO400 is $5000 with 4 * 250GB SATA disks.

Ok.  What for example should I be looking for in terms of specs to make sure that these will work in a clustering situation?  For example, I know why the HP 4314r will not work, what does the IBM not have that will not allow it to work for clustering?  Sorry for all the questions, just trying to understand this a little better.

On second thoughts the EXP300 can be used as shared storage  in a cluster, http://www-304.ibm.com/jct01004c/systems/support/supportsite.wss/docdisplay?brandind=5000008&lndocid=MIGR-4JRR6P "It supports split SCSI bus and clustering configurations"

Very nice.  Well I am going to give that one  a shot.  I have never worked with an IBM storage array anything special with those as apposed to higher end HP's?
