HPE Integrity Servers is a series of server computers produced by Hewlett Packard Enterprise (formerly Hewlett-Packard) since 2003, based on the Itanium processor. The Integrity brand name was inherited by HP from Tandem Computers via Compaq. In 2015, HP released the Superdome X line of Integrity Servers based on the x86 Architecture. It is a ...
a mixture of disk drives configured as RAID 1 (2D+2D and 4D+4D), RAID 5 (3D+1P, 7D+1P, 14D+2P and 28D+4P) and RAID 6 (6D+2P) up to 240 disk drives for 177 TB of raw capacity; up to 64 GiB battery-protected (48 hours minimum), mirrored write cache; virtualization technology provides external storage device support to enable tiered storage up to ...
Diagram of a RAID 1 setup. RAID 1 consists of an exact copy (or mirror) of a set of data on two or more disks; a classic RAID 1 mirrored pair contains two disks.This configuration offers no parity, striping, or spanning of disk space across multiple disks, since the data is mirrored on all disks belonging to the array, and the array can only be as big as the smallest member disk.
Exact specifications depend on the precise version and system configuration. The host configurations are the same as those supported by HP-UX, and can include 128 physical cores and 1TB of main memory. More than 250 guests can run concurrently, although the optimal number is generally lower, depending on host memory and processor configuration.
Device configuration overlay (DCO) is a hidden area on many of today's hard disk drives (HDDs). Usually when information is stored in either the DCO or host protected area (HPA), it is not accessible by the BIOS (or UEFI), OS, or the user. However, certain tools can be used to modify the HPA or DCO.
HPE now owns the ProLiant brand after HP split up into two separate companies in 2015. The HP/HPE ProLiant servers offer many advanced server features such as redundant power supplies, Out-of-band management with iLO or Lights-out 100, Hot-swap components and up to 8-Socket systems.
RAID (/ r eɪ d /; redundant array of inexpensive disks or redundant array of independent disks) [1] [2] is a data storage virtualization technology that combines multiple physical data storage components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
iLO is embedded or available on some HPE ProLiant and Integrity servers. Prior to iLO, Compaq created several other lights out management products. The original was the Remote Insight Board (RIB), which was available as an EISA or PCI expansion card. RIB was replaced with RILOE (Remote Insight Light-Out Edition), which was only available for PCI.
