Few things to consider 1) Are the HBA's for the LTO5 Drives dedicated or do they have other devices.
2) How many LTO drives per HBA? 3) Speed of Fibre 2/4/8Gb .... -----Original Message----- From: ADSM: Dist Stor Manager [mailto:ADSM-L@VM.MARIST.EDU] On Behalf Of Gary Bowers Sent: Monday, May 02, 2011 9:39 PM To: ADSM-L@VM.MARIST.EDU Subject: [ADSM-L] LTO5 performance Just a quick poll of what people are seeing for LTO-5 performance. Is it anywhere close to the rated 140 MB/s native, or much lower? I ask, because I have a customer that is only getting about 40-50 MB/s from HP LTO5 drives in a Quantum library. This number seems really low to me, but before I jump to making recommendations, I would like to have some real world numbers to go off of. You'd think Google would find some, but my searches turned up nill. As an aside, has anyone had performance problems with Quantum libraries and their built-in Fibre Switches? OS is AIX 6, having the same performance from both TSM server, AIX and Solaris 10 LanFree.
