Yes, we need to keep DiskSuite. It

* is used in preference to ZFS by some people
* has a smaller memory footprint than ZFS
* is used with Cluster for globally mounted filesystems
* is widely deployed in existing environments 
* is still used with SAM-FS (just ask dlg!)

Oh, I could go on and on. It should stay. ZFS is not a panacea.
