Hi George,
Have you considered using the built-in RAID available on the AlphaServer 2100 series? This may help your I/O bottleneck considerably.
As with any hardware platform, software (including Oracle) requires tuning to achieve a balanced use of system resources. With Alpha platforms running DEC OSF/1, you can use any combination of ufs, raw devices, RAID, Advanced File System Utilities, and Logical Storage Manager to alleviate I/O bottlenecks.
