Why not go with the SL500 but with the Base+Drive modules only? That would give you the base module with 2 drives and cartridge slots and a Drive Expansion Module with up to 4 more drives (you’d only use 2) and the cartridge slots in that module. That way you have a path for future expansion as well if you need to add more cartridge expansion modules down the road.

Hi Folks,

I am working on a DR solution for my company. I use StorageTek SL500 and L180 with LTO3 fiber attached. Netbackup is tuned with 256K data buffers. Now, I need a smaller tape unit at my active DR site to support reading LTO3 tape media from the primary sites. I looked at SL48, it looks like I can go just with 2xLTO3 full height drives in it to get the same fiber speed. I used a StorageTek L20 in the past with Ultra 160 SCSI LVD and I could not read tapes written with 256k data buffers. And based on the sizing for the business applications in the DR, I would need 4 tape drives at least. I would appricaite, if anybody would give their recommendations.

Thank you,
Boris
