original question

I am interested in the experiences any of you have had with
the SPARCserver manager software; especially the disk meta-partition
capabilities. Do you notice any performance degradation?

not many answers here. It seems that there is no noticeable performance
degradation. SPARCserver manager has been replaced and expanded on
by multiple unbundled and bundled products in 4.1.2 (on-line disk
suite, backup co-pilot, quick check, etc.)

Thanks to all

Works fine, no noticeable performance degradation.
No problems.

Not really - the file system layout seems to have compensated for it.
One thing I'm looking forward to finding out is how much of a difference
striping makes...

[me too, and multi-port controllers]

Matt,

Don't use Server Manager. It's buggy. If you MUST use it, use
it with the Sun patches. Ask Sun support to amplify; if they
don't know what you're asking about, I'll ask my colleagues for
particulars and pass them on to you.

Use Disk Suite instead. It's more functional, it's less expensive,
it's got MUCH more to offer. I think (am almost certain) that it's
less expensive BECAUSE it's more robust and therefore easier to support;
the pricing on Server Mgr was in our opinion meant to be a disincentive.

Let me know if you need details.

Answer:

Sun has an unbundled product called "Disk Suite" that may do what you need.

Online: DiskSuite Can mirror any disk, including the root parition and swap space. Optional three-way mirroring. Hot spare, can copy off of a failing mirror disk while it is online. Disk striping, breaking up large sequential I/O request to several smaller parallel requests to multiple disks on multiple controllers. Online filesystem expansion; concatenate several partitions into one. Maximum filesystem size = 1 terabyte (1 million megabytes). QuickCheck - fast reboot recovery with improved 'fsck'.
