Access to an EMC SAN

We are considering moving some apps from individual blades (a growing expense) to a partition of an existing, underused i520. One hang up is DASD, especially moving or reloading the terabytes of data currently held in our SAN. With the new partioning of an i5, especially when running an AIX, or Windows partition it seems that we might be able to access a SAN. Is this a fair expectation? Has any one had success with this, or are we still tied to the 'internal' iSeries storage?

Thanks. We'll let you know when a new response is added.

If memory servers me correctly, you can attach an AS/400 to a SAN via a scsi channel or a fiber channel you would just need the appropriate IOA to connect the SAN to each partition. A fiber switch would probably be your best bet. Be careful since you have EMC disk though. At a previous job, we had external EMC disk on an AS/400 and the disk itself was a performance bottleneck because it was external as opposed to internal disk.

    We are currently have several of our iSeries systems attached to external DASD. We are currently using 2 IBM Sharks. We have tested the EMC also. You need fiber IOA to the SAN and can even setup Dual Paths. It is still best to keep some of the most used data internal, but we haven't really seen any performance hits as of yet. We have been running this configuration for about 2 years.

    We have Power6 520, and have maxed out on our DASD, could anyone tell me installing VMAX 1.0 as a SAN to iSeries as storage solution? The LUNS are already created and it need just to configure. Any guidance and docs?
