The HP NetServer Solution
The HP NetServer LXr 8500 (see Figure 4), the newest
server in the L series family of servers, establishes a
highly scalable Intel-based architecture for the data
center.
In the beginning of this paper, data centers equipment
needs were listed as performance, availability, and
scalability. The HP NetServer LXr 8500 meets these
needs in the following manner:
• Performance
− Up to 8 550 MHz Intel Pentium III Xeon
processors, reducing the potential for
processor bottlenecks
− Up to 32 GB of ECC SDRAM memory on its
own 64-bit bus, with interleaving to improve
memory bandwidth and reduce access
conflicts
− Up to 4 host-to-PCI bridge chips, connecting to
a 64-bit, dedicated I/O bus, reducing
contention between the I/O and processor
activity, improving throughput and reducing the
potential for I/O bottlenecks.
• Availability
− Redundancy: fans, power supplies, disk drives, network controllers
− Hot swap: fans, power supplies and disk drives so that replacements can be made
without bringing the system down. PCI hot plug support so PCI adapter cards can be
repaired or replaced while the system is up.
− Self-monitoring hardware components (CPU, CPU boards, memory DIMMs, memory
boards, cache coherency filters) de-allocate themselves in case of a failure and
continue server operations without IT intervention.
− “Totally Safe” memory scrubbing utility proactively cleans system memory,
eliminating single bit memory errors and minimizing multi-bit induced system failures.
− Automated failure recovery, including automatic server restart and ECC memory.
Includes One-Button Disaster-Recovery as a tape backup solution to simplify and
expedite system restoration after a failure
− Server clustering: supports cluster capabilities from several vendors
