Universal, but NOT Auto-Ranging. There is a set of spade

Each processor board has a switch on the mounting
bracket, AP or FP.
Each processor board contains a 486DX processor, along
with a Level 2 memory cache, and the attachment to the
Micro Channel. There are two Micro Channels, one with
four slots, and the other with eight slots. The
processor in slot 0 is always connected to the
eight-slot Micro Channel, and the processor in slot 1 is
always connected to the four-slot Micro Channel.
Configuring the Server 295 for
multiprocessor or uniprocessor mode is done using the
utility MPSETUP, which is also used for installing Multi
Processing Extensions/2 and for allocating memory to the
AP and FP processors, and the HPFS cache.
When configured for multi-processor mode, changes are made to the CONFIG.SYS file, and a new CONFIG.FP file is created for the FP processor. However, the utility MPSETUP should always be used to switch between uni-processor and multi-processor modes. It is wise to always return to uni-processor mode before altering the CONFIG.SYS file or upgrading the operating system.
ECC-P Memory with 4MB 30 Pin
So... you need two banks of 4 SIMMs each for ECC-P, so
the minimum is 32MB, the next is four banks (64MB), six
banks (96MB), and 8 banks for a maximum of 128MB.
NOTE: I have seen a
configuration screen, with a choice of "ECC: ON | OFF".
My guess is that ECC=P will not run on an odd number of
banks, so if you wanted to run 48MB, ECC would be "OFF".
Memory Management and OS/2
NOTE: The "RISC"
functionality is inside the 53C700.
Option: 2 additional SCSI controllers (same as above,
on 1 card).
Supports IBM 400 MB (11.5 ms) and 1 GB (11ms) SCSI
Max of 9 GB internally (9 bays x 1 GB disk).

OS/2 preload includes FTUTIL: allows disk pairs to be
striped, mirrored, or duplexed. Also allows hot spare
pooling, hot insertion/extraction, automatic data
rebuild, and hot fix.
One or two disk controllers can be installed on the IP-Bus, providing two or four SCSI disk channels, respectively. Each channel can support up to seven SCSI disks, for a maximum of 28 disk drives.
four disk channels are available, then arrays can be
configured across multiple SCSI channels. SCSI channels
are defined vertically, arrays can be defined
horizontally, thus giving an "orthogonal" configuration.
This provides extra fault-tolerance (since a single SCSI
disk channel, a single cable, or a single disk can fail
without losing the array).
PDAs are set up using the Server 295 reference
diskette. Information on the PDAs can be displayed
using MASS/2. Configuring spare drives and
reconstructing a PDA following a drive failure is done
using the utility PDAUTIL, as well as automatically by
MASS/2, if there is a hot-standby spare disk in the

Note 2 : Availability = MTBF of one disk divided by the number of disks in the array.
(Maximum Availability and Support System/2)
Integrated software allowing monitoring, controlling,
tuning, and recovery of 295. Allows 295 to be
geographically distributed while permitting
comprehensive, centralized control with mainframe-like
remote administration. Features:
Continual monitoring of CPU, memory, disk,
network, and swapping level utilization via realtime bar
graph, and 1 hour history in RMP RAM, and historic logs
Continual monitoring of temp, PSU voltage,
single bit memory errors, network errors.
Comprehensive configuration details (processors,
memory, SCSI, arrays, spares, RMP, UPS status,
Alarm and threshold selection with automatic
dial out capability for various events like disk
failure, disk full, reboots, shut downs, memory errors,
over temperature, power low/high, and network errors.
