Re: TSM server on Linux w/3494-3590

Hi

We have Linux running on two sites. 

The Linux server is fairly good in performance, but I would consider it 
for a mid-sized platform. The I/O and processor architecture of the x86 on 
which you run the TSM server will have I/O constraints when having 
environments with a daily incremental >200GB each night. Also, looking at 
x86 boxes today, the PCI architecure cannot really compete with UNIX 
boxes. Normally, the UNIX boxes has a lot more PCI-buses, which is a 
requirement when running multiple FC adapters to tape and disk.

Also, I would consider a fairly large UNIX box a lot more stable than 
running on a x86 box, when it comes to error detection, processor handling 
and redundancy.

Best Regards

Hi Zoltan!
I'm not an expert, but is the x86 bus architecture not a bottleneck for 
high
volume high performance I/O?
Kindest regards,

We are investigating the issue of moving TSM off AIX to a Linux system,
purely due to the cost of AIX hardware (lets face it....when it costs me
$5000 for a drawer of used SSA drives just to get me 130GB of raided disk
when I can get complete multi-processor x86 boxes with 300GB of raided
disk for the same cost, you have to investigate !)


The only issue is the fiber-channel/SAN connectivity to the shared 3494
ATL (primarily used by our z/OS systems) using 3590 E1A drives.

Can this be accomplished with an x86 box ?

How many folks are using the fairly new Linux version of TSM ?   How is it
running ?    Issues ?
