Our DBA's are currently testing a product called SQL LiteSpeed.  When it was 
installed the TSM backup archive command line and GUI stopped working.  When 
you would launch either they would hang and never start.  I thought IP or port 
issue but the TSM admin command line which was set to use the same port (4081) 
had no problems.  They removed the software and everything worked again. This 
problem also effected the TDP for SQL, I believe because it effected the TSM 
client api.

Has anyone else used SQL LiteSpeed before?  If so any pro's con's?

If you have used SQL LiteSpeed did you notice any problems with TSM after it 
was loaded?

For those who don't know but care to SQL LiteSpeed can be used to backup SQL as 
well and is touted for having really good compression. It compressed a 2.5 TB 
SQL database down to 356 GB.  They are thinking of using this and the TSM 
client instead of the TDP.  We ran a TDP LanFree test today with 10 stripes and 
it backed up 2.5 TB's in 5.1 hours (~477 GB/hr).  We believe our bottleneck was 
the disk we were reading from.  We have seen that we can push a single tape 
drive to 100 GB/hr.  So using SQL Lite would reduce the backup from 5.1 hours 
to around 3.5 hours.
