IBM recently introduced a RISC-based eServer pSeries server that runs Linux as its native operating system, while Hewlett-Packard announced two Intel-based ProLiant servers and a processor upgrade to another ProLiant server.
The IBM eServer p630 uses one to four 64-bit IBM Power4 processors that can be partitioned to run separate applications or operating systems. For instance, the p630 could be deployed in an Internet infrastructure where Linux-based Web applications run on one partition while Unix-based application server software runs in the midtier on another partition.
The p630, while shipping with Linux, also works with IBM's AIX 5L. The server starts at US$16,730, preconfigured with Linux.
HP last week announced the ProLiant DL320 and DL360 for enterprise-size businesses where space is constrained. The company also updated the ProLiant DL580 with a new processor, Intel's Xeon MP.
The DL360 and DL580 use HP's Advanced Memory Protection, which includes online memory spares, memory mirroring and hot-pluggable memory. With online spares, memory sits in standby waiting to be deployed if primary memory fails. In mirrored memory, changes are written simultaneously to primary and secondary memory. Hot-pluggable memory can be replaced without taking the system down. All three memory technologies provide increased availability and fault tolerance. Like IBM's ChipKill and bit-steering, they are technologies that have migrated down to low-end servers from midrange and high-end systems.
The DL320, DL360 and DL580 also use HP's Remote Lights-Out (RILOE) technology, which allows the remote management of a server from the ProLiant Essentials software and the Rapid Deployment Pack. RILOE is a standard feature on the DL360 and DL580 and an optional upgrade on the ProLiant DL320 server.
The DL580 is designed for use in enterprise-size data centers and can be expanded from one to four Xeon MP processors.
The DL360 is a single processor 1U (1.75-inch-high) server that operates at 2.4 GHz or 2.8 GHz and uses Intel Xeon processors. The DL360 has a hot-pluggable power supply.
The DL320 uses a 2.26-GHz Pentium 4 processor.
All servers are available in the US now. The IBM p630 starts at US$16,730. The ProLiant DL580 starts at US$7,200, the DL360 starts at US$2,600, and the DL320 starts at US$1,450.
