HP Proliant Glossary

1/2/4 Way Servers - Relates to the amount of processors supported.

BL Server - Otherwise known as a Blade Server.Blade servers are self-contained/ all inclusive computer servers, designed for high density. blade servers have many components removed for space, power and other considerations while still having all the functional components to be considered a computer.

Blade Enclosure - A server chassis housing multiple thin, modular electronic circuit boards, known as blades. Each blade is a server in its own right, often dedicated to a single application.

DL Server - Otherwise known as Density Line Server. Rack mount ProLiant server. Here, HP puts as many features as possible in as small an enclosure as possible. 1 U (rack unit, 1.75") is the smallest. It is a complete server and does not share components (like power and cooling) with other servers (like blades)

DAS (Direct Attached Storage) - A deployment of dedicated storage devices for each server, usually using SCSI cabling or technology. Can be an inefficient use of storage, plus DAS environments often involve a
mix of different vendor storage and management interfaces.

Data replication - The process of mirroring data between two locations to ensure data availability in the
event of a complete data-centre outage.

DtS (DAS to SAN technology) - An exclusive HP feature that provides a quick and easy way to migrate disks and stored data running on Smart Array or RA4100 storage solutions to an HP StorageWorks MSA500 G2, MSA1000 or MSA1500 disk array.

Dual Core - A single chip that contains two distinct processors that work simultaneously

FATA (Fibre Attached Technology Adapted) - High-capacity, low-cost-per-gigabyte FC drives for cost-
effective storage of less critical or infrequently accessed information. Plug-and-play compatible with
existing HP StorageWorks EVA systems.

FC (fibre channel) - A technology for transmitting data between servers and storage devices at high-speed. Fibre-channel configurations use fibre-optic cabling, connected to switches, host bus adaptors or fibre-channel controllers.

Gigabit Ethernet - A transmission technology based on the Ethernet frame format and protocol used in local area networks (LANs), provides a data rate of 1 billion bits per second (one gigabit).

HBA (host bus adaptor) - A PCI adaptor that connects a server to the SAN fabric. Each HBA installed is referred to as a host.

HP Renew - Offers quality remanufactured server and storage products covered by the original HP warranty at exceptional prices. All HP Renew products are remanufactured to original specifications in factories owned and managed by HP. Products from the HP Renew portfolio are at least 15-40% below the price of new.

Inisight Control - Insight Control is a set of software tools designed to make managing your HP ProLiant
and BladeSystem environments simple. The result is significant savings - both in time and money.

ILo - HP Integrated Lights-Out is a lights-out remote management processor integrated on most ProLiant servers which gives you virtual presence, i.e. complete control as if you were in front of servers in
datacenters or remote sites. This means you are always in control regardless of server status or location.

LAN-free backup - A configuration where data backup/restore operations take place over a fibre-channel connection instead of a LAN.

ML Server - Otherwise known as maximised Line. These are typically ProLiant servers in a tower enclosures but there are several in rack enclosures. Here HP gives you more slots for option cards and more drive bays and typically, more memory slots. They are also complete servers that do not share components like blades.

MSA (Modular Smart Array) - HP’s family of entry-level storage arrays, spanning from SATA and SCSI
disk enclosures up to shared storage and SAN arrays.

Near-online - A new class of low-cost disk drives to store data with low performance requirements.

Quad Core - A single chip with four distinct processors that work simultaneously

Rack Sever - A rack server, also called a rack-mounted server, is a computer dedicated to use as a server and designed to be installed in a framework called a rack. The rack contains multiple mounting slots called bays, each designed to hold a hardware unit secured in place with screws. A rack server has a low-profile enclosure, in contrast to a tower server, which is built into an upright, standalone cabinet.

RAID (Redundant Array of Independent Disks) - A method of writing data simultaneously over multiple
disk drives used in disk arrays for increased protection.

Replication - Mirroring data between two arrays – usually located in separated data centres – to achieve highest availability in case of failure of one data centre. This can be achieved via host/IP-based replication
or – for enterprise arrays such as EVA or XP – via SAN-based replication directly between two arrays.

SAN fabric - The hardware that connects workstations and servers to storage devices in a SAN. It enables any-server-to-any-storage-deviceconnectivity through fibre-channel switching.

SAN (storage area network) - High-speed, special-purpose network connecting different data storage devices to servers. May extend to multiple or remote locations for backup and archival storage.

SAS - Short for Serial Attached SCSI, an evolution of parallel SCSI into a point-to-point serial peripheral interface in which controllers are linked directly to disk drives.

SATA (Serial ATA) - A low-cost disk technology compared to SCSI- or FC-based disks. Ideal for storage
of less-critical data that doesn’t require optimum performance or reliability. Available with the HP StorageWorks MSA1500.

SCSI - Short for small computer system interface, is a set of electronic interfaces that allow personal computers to communicate with peripheral hardware such as disk drives, tape drives, CD-ROM drives, printers, and scanners faster and more flexibly than previous interfaces.

Serverless backup - Disk-to-tape backup with minimal or no data passing through the server – improving performance for users.

Single Core - A chip with one CPU (one processing unit).

Snapclones - A Snapclone starts as a Snapshot, which can immediately be presented to a server for
reads and writes. At the time of the creation of the Snapshot, the array controller starts copying data from
the virtual disk to the Snapclone virtual disk to create a full, identical copy.

Snapshots (Vsnaps) - Virtual disk Snapshots are disk-based copies of stored data that reduce backup windows to seconds. A Snapshot only replicates pointers to data – not the actual data itself – meaning
they are virtually capacity-free.

Switch - A network device that selects a path or circuit for sending a unit of data to its next destination.

Tower Server - A tower server is a computer intended for use as a server and built in an upright cabinet that stands alone. The cabinet, called a tower, is similar in size and shape to the cabinet for a tower-style personal computer. This is in contrast to rack servers or blade servers, which are designed to be rack-mounted.

Virtualisation - Technology that simplifies the complexity of array management and increases flexibility, availability and performance.
