"it depends" on your infrastructure, and what your actual performance issue is.
LAN-free was invented when fibre connections were substantially faster than connections over 10/100 Lan. Now I have customers where the network/LAN connection is faster at 10GE than their fibre at 4GBit or 8GBit. Your network connections are probably GIG/E (max 100 Megabytes per second) or 10GE (1000 Megabytes per second). Your fibre connections for LAN-Free are probably 4Gbit (400 Megabytes per second) or 8Gbit (800 Megabytes per second). And, The fact that you have a fast connection between your Exchange server and your TSM server, doesn't necessarily mean your Exchange server is capable of moving the data at max possible speed. So * do you have a performance problem? * what is the speed of your network connection from the Exchange server to the TSM server? * are you sure that the performance problem is the network speed and not in the Exchange server itself (are you sure it isn't CPU-bound or disk-I/O bound? have you run a trace?) * is the problem that your TSM server NIC is too busy to accept the data from Exchange? In that case the simpler solution might be to add a NIC to your TSM server. * if your site is planning to upgrade to 10GE in the near future, that is a simpler solution (no additional management overhead for you, no HBA or fibre port needed) * do you have tape drives available for Lan_Free? * is the bottleneck in the diskpool on your TSM server? If so have you tried sending Exchange backups direct to tape? * can you put the necessary HBA's for the fibre connection into your Exchange server? After call those considerations, consider Lan-Free. -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of duholm Sent: Friday, April 05, 2013 5:03 AM To: [email protected] Subject: [ADSM-L] Exchange backup performence Hi All I was hoping someone would know if Exchange backup is faster using LAN-free instead of the normal LAN backup. If it is how much faster?
