The TSM HSM RPM's for what ever version of TSM you are running on the TSM server. Then schedule some downtime on the file system as you will have to umount it to enable DMAPI/HSM on the GPFS file system it :-) But really HSM on GPFS is something of a "minority sport". If you need to ask thes basic questions I would seriously consider whether it is a good idea. My experience is that HSM on GPFS makes the whole thing an order of magnitude flakier and there is a whole pile of "gotchas" that just don't apply if you are running a bog standard GPFS file system. If HSM is an absolute requirement then you need to go on some training first. In my view you need to thoroughly understand both TSM and GPFS *BEFORE* you embark down this course. Personally I would go and by some MD3660f's or MS3260's from Dell; 60 drives in 4U things. Stuff them full of 4TB or larger hard disks whack expansion shelves on them as required, create some dynamic disk pools, stick them in another storage pool and then do some tiering and avoid HSM altogether. These days HSM only makes sense on upwards of 500TB probably 1PB data on tape and I would imagine that a two GPFS server, one HSM server system is just not of that order of magnitude.

Simple enough to do, I guess. We run TSM on a server nodes, but those nodes are not an NSD nodes, just CNFS nodes (but they still have the server license). We found that TSM backs up significantly faster from non-nsd nodes. There isn't much to the HSM as far as components. Just the rpms/debs. Mostly it's a setup issue with the DMAPI on the servers, the config files for the HSM and TSM. If the HSM works fine from a client node, the servers would still have to have DMAPI enabled.

The TSM HSM RPM's for what ever version of TSM you are running on the TSM server. Then schedule some downtime on the file system as you will have to umount it to enable DMAPI/HSM on the GPFS file system it :-) But really HSM on GPFS is something of a "minority sport". If you need to ask thes basic questions I would seriously consider whether it is a good idea. My experience is that HSM on GPFS makes the whole thing an order of magnitude flakier and there is a whole pile of "gotchas" that just don't apply if you are running a bog standard GPFS file system. If HSM is an absolute requirement then you need to go on some training first. In my view you need to thoroughly understand both TSM and GPFS *BEFORE* you embark down this course. Personally I would go and by some MD3660f's or MS3260's from Dell; 60 drives in 4U things. Stuff them full of 4TB or larger hard disks whack expansion shelves on them as required, create some dynamic disk pools, stick them in another storage pool and then do some tiering and avoid HSM altogether. These days HSM only makes sense on upwards of 500TB probably 1PB data on tape and I would imagine that a two GPFS server, one HSM server system is just not of that order of magnitude.

Simple enough to do, I guess. We run TSM on a server nodes, but those nodes are not an NSD nodes, just CNFS nodes (but they still have the server license). We found that TSM backs up significantly faster from non-nsd nodes. There isn't much to the HSM as far as components. Just the rpms/debs.

Currently playing with GPFS installed in PowerKVM hypervisor layer - a great backing store for the VM images. Having fun with the 4.1 GUI for another customer, but providing a front end script for them to manager their snapshots until the GUI is released.

I?d like to see all timings, especially those related to the Infiniband layer (i.e. verbs). I remember that Sven Oehme told us (in the last GPFS UG in London) about new performance measurements in GPFS v4. I have tried the new mmdiag --rpc command but honestly I was not able to understand the result properly. I also tried the dstat python plugin, but I didn?t see any new timings related to Infiniband. So I?m wondering wether or not I was dreaming somehow during the meeting ?!? Can someone enlighten me on this ? Many thanks.
