A close look at 95 series processor complexes (215kb)

General information
Machine type: 9595
Announce date: October, 1992

Excerpt from the original announcement letter;

"The Personal System/2(R)(PS/2(R)) Model 95 XP 486 family of systems is expanded to include International Organization for Standards (ISO) capable servers. These new 9595 machine type systems replace selected models of machine type 8595. The PS/2 Model 95 XP 486 (9595-0LF, 0MF and 0MT) system units feature the IBM PS/2 XGA(tm)-2 Display Adapter/A with 256 colours, higher screen refresh rates and non-interlaced scanning, providing enhanced ergonomic benefits in the form of reduced screen flicker at high resolution (1024 x 768) when used in conjunction with appropriate software and the new IBM 95XX Colour Monitors. The PS/2 Model 95 XP 486 (9595-0LF, 0MF and 0MT) system units support the same features and provide the same basic functions previously announced with the corresponding 8595 system units. All IBM 9595 systems will be shipped by IBM with OS/2 and will include a mouse at no additional charge."

NOTE: 95A comes with Fast & Wide RAID adapter, but only Fast drives!
NOTE: 0Mx & SERVER 95 models come w/ ECC (Error Checking & Correcting Memory)
NOTE: 9595 XP models are identical to 8595 XP models but with these additional features:
1. ISO-compliant
2. Premier line has 3 year on-site warranty
3. XGA-2 with 1MB VRAM

SERVER 95 models are different, part number-wise and functionally.
1. SERVER 95 comes with SCSI-2 Fast adapter
2. 95 ARRAY models come with SCSI-2 Fast/Wide RAID controller - supporting RAID levels 0,1 or 5, and "spare pooling". The drives are hot-pluggable. The 95A comes with 3 hard drives configured in one array, but NOTE that they are Fast, not Fast & Wide, drives.
3. All SERVER 95's (including ARRAY) have SVGA adapters
4. All have SurePath BIOS, upgradeable by flash EPROM
