– Keyboard and mouse ports
These are standard on the system and are made available without utilizing any of
the expansion slots provided.
Industry-standard PCI subsystem supporting 32-bit and 64-bit adapters.
Greater application throughput is achieved via independent PCI buses for
each of the 14 PCI slots in the I/O drawer. This design provides up to 1 GBps
aggregate bandwidth per drawer, depending on system configuration. The
7026-H80's independent PCI busses are designed to enhance reliability by
isolating adapters from other adapters within the drawer.
A high-performance ECC L2 cache of 2 MB on the 1-way processor and 4 MB
per processor on the 2-, 4-, and 6-way processors is provided.
RAID support available for SCSI and SSA. The operating system provides
RAID 0 and 1. The optional SCSI and SSA RAID adapters provide RAID level
0, 1, and 5.
Product positioning
The 7026-H80 consists of a rack-mounted Central Electronics Complex (CEC)
drawer containing the processors and memory connected to another
rack-mounted drawer containing the media, hot-plug I/O slots, and optional boot
bays. Both drawers have redundant power options and redundant cooling. The
introduction of hot-plug PCI I/O slots brings new and increased levels of
availability for this system. The need to power down and reboot when adding or
replacing most PCI adapters is eliminated, thus reducing time delays while
keeping network and application processing up and running. The 7026-H80
system can accommodate 1 processor module in its smallest configuration and
grow to 2, 4, or 6 processors as required, offering scalability as your business
needs dictate.
The 7026-H80 is targeted at the key commercial processing segments of
e-business, ERP, SCM, and Business Intelligence. In each segment, the
7026-H80 can meet critical requirements. For example:
In ERP, the 7026-H80 is an application server with its powerful processors,
memory capacity, and optional data storage capability.
In e-business, the 7026-H80 can serve as a business- to-business Web
server, going to other systems for business data or hosting the data storage
itself.
