Hewlett-Packard recently introduced two Intel-based servers that let users increase protection for memory, while growing the server for performance.
The ML570 and DL380 use the recently introduced Pentium 4 Xeon chipset that was codenamed "Gallatin." The ML570 is a four-processor server, and the DL380 is a dual-processor server. The DL380 is rack-mountable and 2U (3.5 inches) high.
Each server features hot-add memory, allowing users to add memory to the server without taking the server down. They also feature lights-out management, the ProLiant Essentials Foundation Pack and SmartStart management software, which provide server configuration and deployment options.
The ML570, with hot-pluggable mirrored memory and seven PCI-X slots, is designed for data center or remote enterprise locations. It features hyperthreading, in which multiple instances of the processor can share memory and other resources, thus increasing the efficiency and performance of the server.
Further, the ML570 operates at 1.4 GHz and has 512K bytes of L3 cache, a 400-MHz front-side bus and an embedded 10/100M bit/sec Ethernet adapter. It comes in rack or tower configurations. It has an embedded dual-channel Ultra 2 SCSI adapter for attachment to external storage. The ML570 is 7U (12.25 inches) high.
The DL380 has six bays for drives and three expansion slots. Two of the expansion slots can contain hot-pluggable drives, allowing an IT manager to change out failed or problematic drives without taking the system down. It also includes optional redundant power supplies and cooling, and internal tape drives. It features dual Gigabit Ethernet network adapters and a battery-backed-up write-through cache for fault-tolerance. The server runs at 2.8 GHz and has 512M bytes of memory and an embedded Ultra3 SCSI RAID controller for attachment of external storage.
The HP ProLiant DL380 stars at US$4,000; the HP ProLiant ML570 starts at US$6,920.
