Re: Advice on setting up minidisks
At first, when Mark suggested only -9 and -27 disks, I disagreed with him. After a day, I started agreeing with him. Now I'm back to disagreeing with him. I guess it all depends First, you have to go back to hardware. You can only create 256 drives out of any RAID array. On the DS6800/DS8100, if you are using 72 GB drives, if you only define mod-3s, you can't use all the space available. And this gets worse as you go to the 145 GB drives, the 300 GB drives, the 500 GB drives and the 1 TB drives. You just have to have some/many large 3390s in order to use all the space. Mark is pretty much correct, that 3 3390-3 vs 1 3390-9 are the same. If they are on the same raid array there isn't much performance improvement unless you consider that you can only do 1 I/O per device at the same time, unless you use PAV (and paid for that feature). Consider that a mod-27 will be only on a single RAID array. Divide it into 3 3390-9 and you can put each one on a different array. Now you can truely do multiple I/Os at the same time. In my case, I do have some larger Linux guests, but I do have a bunch of small ones. Really they could be on a 3390-1, but, eventually, some of them, due to software installs, tend to grow and I need more space. Their data, however, I either have as LVM (yep, larger capacity drives work well here), or NFS mounted space. So my root drive is usually a 3390-3. HOME and other data directories are on LVM or NFS space. For example, my Oracle servers use LVM for local Oracle tablespace. However, it backs up to a NFS server. That NFS server is an easy place for me to backup all the data from multiple machines to tape. The Oracle server is physically backed up weekly with FlashCopy and that flashed image is then backed up to tape as a physical image. This is used for disaster recovery purposes. My point is that small drives have their purpose. But I also would tie together a dozen mod-3 drives if I had the option to tie together a lessor amount of mod-9 drives (or higher capacity). If you need I/O performance, make sure you spread your data across several arrays. This may require you to do smaller drives. I can sure tell the difference when I copy a GB file when from/to are on the same array vs from/to being on different arrays. BTW, I'm not sure why someone would do this, but you can create mod-10, mod-11 mod-xx drives in the IBM Dasd Subsystems. Any size is really available. But you may face issues of "standards". Just another opinion Tom Duerbusch THD Consulting >>> Ron Foster at Baldor-IS 1/13/2011 1:41 PM >>> Hello list, This may have been discussed before... Way back in deep dark ancient history, we used the Redbook to get started with Linux under z/VM. As a result, we carved up our storage subsystem in to a bunch of mod3 drives.

Re: Advice on setting up minidisks
Our current situation is MOD 3 for Z/VSE and z/VM and MOD 9 for zlinux We will be migrating to an new DS8800 and we are still discussing about how we will use our drives. We will probably do something like this. We have ordered HyperPAV licensing for the SAN: MOD3: For linux swap disks and VM paging disks. MOD 9: Linux system disks MOD 27: disks for logical volumes. We are still running SUSE 10 that doesn't support HyperPAV. So we will still use MOD 9 for the logical volumes in production until we migrate to SUSE 11 and when we have tested the performance implications of going from MOD 9 to MOD-27 with PAV (Theoritically it should give better performance, but better to be safe than sorry) For the development, test and acceptance machines we will start using MOD 27 with normal PAV. You should definitly check out hyperPAV. The extra license price was in our case peanuts considering the potential performance boost. And hyperPAV doesn't need any configuring in SUSE 11, so no extra work there.
