HP ProLiant Essentials Workload Management Pack

Developed exclusively for Windows 2000, HP ProLiant Essentials Workload Management Pack
featuring Resource Partitioning Manager (RPM) increases the stability and availability of applications
under Windows 2000 to allow customers to confidently deploy multiple applications on a single
server. RPM builds upon the embedded job object technology in Windows 2000 to provide a quick
and easy way to manage processor and memory resources dynamically.

Advanced memory protection

Business dependency on industry-standard servers to run memory-intensive applications with Windows
2000 is pushing the memory capacity of servers to new levels. As server memory capacities increase,
so does the likelihood of memory errors that can corrupt data and cause servers to crash. HP
Advanced Memory Protection provides increased fault tolerance for applications that require higher
levels of availability. HP ProLiant 300, 500, and 700 Series servers feature one or more Advanced
Memory Protection technologies: Online Spare Memory, Hot Plug Mirrored Memory, and Hot Plug
RAID Memory.

Online spare memory

Online Spare Memory is a spare bank of DIMMs for system memory failover. When a DIMM in
system memory reaches a defined threshold of single-bit errors, the system will failover to the spare
bank without intervention or server interruption. Online Spare Memory benefits customers with sites
that cannot afford unscheduled downtime from memory errors, yet can wait until scheduled downtime
to replace failed DIMMs.

Hot Plug mirrored memory

A redundant memory board mirrors system memory, which provides protection against correctable
(single-bit) and previously uncorrectable (full 8-bit multi-bit error) memory errors. It also allows the user
to hot plug suspect or failed memory without shutting down the server. Hot Plug Mirrored Memory is a
more fault-tolerant option for sites that cannot afford downtime from memory errors and do not want
to wait until scheduled downtime to replace failed DIMMs.

Hot Plug RAID memory

Much like with RAID disk technology, Hot-Plug RAID Memory provides the highest level of fault
tolerance with a minimum of spare DIMMS. HP ProLiant servers offering Advanced Memory Protection
are listed in Appendix a.

Wake on LAN (WOL)

A system that supports Wake on LAN can remain available to a systems administrator during its
normal downtime. Once the machine is awakened, the systems administrator can remotely control,
audit, debug or manage the machine. HP ProLiant servers supporting WOL (at time of publication)
are listed in Appendix a.
