We are curerntly using internal disks on the IOS. With the P770, we plan to move from internal disk to XIV SAN disk. From looking at the Redbook, we cannot go directly from XIV to Iserver, but must go through VIO servers. Is anyone using the XIV storage with iSeries? What is your configuration?

Can you assign virtual fibre channel adapters from the NPIV capable adapters on the VIO servers to iSeries LPARS?

Does routing XIV SAN disks to an iSeries LPAR require a SVC to be between the XIV and the VIO server?

Thank you!!

first, u can use online data migration with migratepv, from local to san disk, there are 2 way for san disk add to p7 lpar,
1. you can add disks to vio and map to a vhost with vscsi
2. you can add disks to vio's fscX port and map this npiv port to vfchost0 with virtual fiber channel,

you need to install xiv_host_attachment scripts to VIO on first way,
you need install to lpar on second way,

migratepv for aix ofcourse i saw now :) similar on ios, you can use SST menu for this,

concerning the 2 ways you mentioned to map disks through vio - (1) either through vio or (2)direct mapping with fc adapters - the XIV Redbook says IOS cannot do #2 (map via fc adapters) - that it must go through vio servers.
Have you successfully mapped disk from XIV directly thrugh fc adapters to IOS?
If you are going through vio for your disks, are you using SVC or not?
Thank you!

DS storages have some abilities for ibm i, soo this storages can attach directly to lpars or npivs, but XIV... u have to attach XIV to VIO for IBMi, it's mandatory (attachment). i used both of them for aixs but only vscsi for ibmi, soo i'm not sure about npiv. i searched little bit and found this notes,

no, i'm not using svc

Thank you again. Is there any performance slowdown you have noticed using san disk on the Iseries versus using internal disk for the I?

Also you mentioned you were using AIX with NPIV. We wanted to get some feedback on performance from other users on this. How many active NPIV virtual wwn's per adapter are practical - there are limitations and it depends on IO load but have you seen any benchmarks or had any experience wtih when the adapter becomes a bottleneck?
