Pam, Here are some things I would suggest checking: - The #5065 Storage/PCI Expansion Tower was announced with V4R4 so I assume that it is still supported by that version. It is an SPD optical-attach tower supporting PCI disk and cards. It should support the current Ultra2 SCSI disks. IBM has offered a field conversion (at charge) of this tower to one of the newer HSL-attached #5074 or #5079 I/O Towers so it would not need to be discarded if you upgraded entirely to 8xx generation hardware. I would see if it is still available. According to IBM's Sales Manual, it has not yet been withdrawn, but that isn't always a reliable source. I'm not sure why you would need to discard it when you finally upgrade you OS. The 720 generation hardware should be well supported for a while. It's worth exploring. There may well be some gotcha that I haven't noticed. Getting accurate information on a configuration is difficult. Sometimes the only way to find out if something is available is to have a vendor configure it as an official IBM MES and make sure the system doesn't choke on it.
