New Tape Systems for SMB clients

Wrapping up my week on the Feb 12 announcements, I will finish off talking about thenew Half-High (HH) LTO4 drives available for our TS3100 and TS3200 tape libraries.
Small and medium sized business (SMB) clients are looking for small, affordable tapesystems. Tape is inherently green, using orders of magnitude less energy than disk,and is very scalable by simply purchasing more tape cartridges.
As a follow-on to our HH LTO3 drives, IBM is the first major storage vendor to offerthe new HH LTO4 drives in entry-level automation, which directly attach via 3Gbps SAS connections to your host servers. The HH models allows you to have two drives in the TS3100, and four drives in the TS3200.
You can mix and match, LTO3 and LTO4. Why would anyone do that? Well, the Linear Tape Open [LTO]consortium --made up of technology provider companies IBM, HP and Quantum--decided to support N-2 generation read, and N-1 generation read/write. So, anLTO3 can read LTO1 cartridges, and read/write LTO2 and LTO3 cartridges. TheLTO4 can read LTO2 cartridges, and read/write LTO3 and LTO4 cartridges. For SMBcustomers that still have some LTO1 cartridges they might want to read some day,mixing LTO3 and LTO4 is a viable combination.
Of course, IBM still offers full-high (FH) versions of LTO3 and LTO4, which offer a bit faster acceleration, back-hitch and rewind times than their HH counterparts, and also offer additional attachment choices of LVD Ultra160 SCSIand 4 Gbps Fibre Channel as well.
So, for SMB customers that are simply using their tape for backup and archive,and probably not driving maximum rated speeds, having twice as many slowerdrives might be just the right fit.
