Description
The 7026-M80 delivers a cost-efficient growth path to the future. It provides
64-bit scalability via the 64-bit RS64 III processor packaged as 2-way and 4-way
cards. With its two processor positions, the 7026-M80 can be configured into 2-,
4-, 6-, or 8-way SMP configurations. The 7026-M80 also incorporates an I/O
subsystem supporting 32-bit and 64-bit standard PCI adapters. The 7026-M80
has 2-and 4-way processor cards that operate at 500 MHz and incorporate 4 MB
of L2 cache per processor.
The 7026-M80 is packaged as a rack-mounted Central Electronics Complex
(CEC) drawer, cable attached to rack-mounted Remote I/O (RIO) drawers. The
CEC and I/O drawers offer redundant power and redundant cooling. The CEC
drawer incorporates the system processors, memory, and supporting systems
logic. The primary (first) I/O drawer features:
14 available hot-plug PCI slots
System support (service) processor
An optical storage device capable of reading CD-ROM discs
Diskette drive
One additional media bay
Integrated SCSI
Ethernet port
Keyboard port
Mouse port
Four serial ports and one parallel port
Up to three secondary I/O drawers can be added to provide up to a total of 56
PCI slots and eight media bays. System storage is provided via remotely
attached SCSI, SSA, or Fibre Channel storage subsystems.
A fully configured 7026-M80 system would include:
Two 4-way SMP card with 4 MB L2 cache per processor
32 GB of system memory
56 available hot-plug PCI slots
7 available media bays
The 7026-M80 CEC and I/O drawers are mounted in the IBM 7014 rack.
Additional space in the 7014 rack may be utilized for various storage and
communications subsystems.
