Introduction 5
Up to three SSA RAID Adapters can be installed in the Netfinity 7000. This
means that up to 288 disks can be connected to one server. With 9.1 GB disks,
this equates to 2.6 terabytes of online storage.
Note: In your RAID configuration planning, remember that Windows NT restricts
the number of usable data and system partitions throughout the amount of
available drive letters.
At the moment you can connect only hard disk drives to an SSA adapter. You
cannot connect CD-ROMs, tape drives or any of the other devices as you can
with SCSI. Therefore, if you want to use SSA, you will most likely need to use
SCSI as well.

1.1.1.5 IBM ServerProven Solutions
You can get a lot of approved, tested and supported IBM and non-IBM options for
your Netfinity servers. IBM created for this purpose the ServerProven program.
IBM ServerProven is a compatibility program for IBM and third-party hardware
options, network operating systems and complete application solutions to
thoroughly test and validate compatibility with IBM Netfinity and IBM PC Server
systems. So you reduce the integration risks for a complete solution and your
installations are more fine-tuned and implementations are more reliable. This
gives you the flexibility to extend your Netfinity Servers with capabilities you need.
