OfficeMax is in the midst of converting over to STK's T9940B drives,
connecting them via 2Gbit Fiber Channel through EMC (read McData) edge
switches to a pair of Sun E6500 media servers.  Although we are still
struggling with the Emulex HBA's performing at much less than expected
throughput we have already observed these T9940B drives running at speeds
over 45Mbytes/sec.  In addition, the 3.3TByte production SAP database now
takes up 4 (yes, you are reading that correctly, four!) T9940 cartridges.
That is to say, we have data cartridges with more than 1 Terrabyte of data
on them!

Of course these T9940B drives do not come cheaply :-)

What about the Storagetek 9940B drives? Does anyone
have any experience with them?
