Automatic Server Recovery will reboot and restart the server if the OS hangs without user intervention

Asset Tag

A changeable asset control number and is used for identification purposes.

Blade server

A server that is located in a rack or enclosure.

Burst Extended Data Out

A variant on EDO DRAM in which read or write cycles are batched in bursts of four. The bursts wrap around on a four byte boundary which means that only the two least significant bits of the CAS address are modified internally to produce each address of the burst sequence. Consequently, burst EDO bus speeds will range from 40MHz to 66MHz, well above the 33MHz bus speeds that can be accomplished using Fast Page Mode or EDO DRAM.

Critical status

A state generated when HP Systems Insight Manager can no longer communicate to a managed system.

DIMM

The dual inline memory module or DIMM is a newer memory module, intended for use in fifth- and sixth-generation computer systems. DIMMs are 168 pins in size, and provide memory 64 bits in width. They are a newer form factor and are becoming the de facto standard for new PCs; they are not used on older motherboards. They are also not generally available in smaller sizes such as 1 MB or 4 MB for the simple reason that newer machines are rarely configured with such small amounts of system RAM.

enclosure

A physical container for a set of blades servers. It consists of a backplane that routes power and communication signals and additional hardware for cabling and thermal issues. It also hosts the CPU or server power supplies.

Event

Information sent to certain users that something in the managed environment has changed. Events are generated from SNMP traps and are preconfigured in this release. HP Systems Insight Manager receives a trap when an important event occurs. Events are defined as:

  • Informational. Events of this type require no attention and are provided as useful information.

  • Normal. Events of this type indicate that this event is not a problem.

  • Minor. Events of this type indicate a warning condition that can escalate into a more serious problem.

  • Major. Events of this type indicate an impending failure.

  • Critical. Events of this type indicate a failure and signal the need for immediate attention.

Hardware Status

The operating state of the system. A hardware status is determined by polling WMI information from the system. Status is defined as:

  • Critical. HP Systems Insight Manager can no longer communicate with the system. The system was previously discovered, but cannot be pinged. The system might be down, powered off, or no longer accessible on the network because of network problems.

  • Major. A problem exists.

  • Minor. The system is functioning but with errors.

  • Normal. The system is functioning correctly.

  • Unknown. HP Systems Insight Manager is not able to obtain management information about the system.

  • Disabled. A problem exists.The system is not functioning.

Identification

An aspect of the discovery process that identifies the management protocol and type of system.

Internet Protocol (IP)

Specifies the format of datagrams (packets) and the addressing scheme on a network. Most networks combine IP with Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source.

IRQ

Interrupt Request Lines are lines over which devices can send interrupt signals to the microprocessor.

PCMCIA

Personal Computer Memory Card International Association is an organization consisting of some 500 companies that has developed a standard for small, credit card-sized devices, called PC Cards. Originally designed for adding memory to portable computers, the PCMCIA standard has been expanded several times and is now suitable for many types of devices. There are in fact three types of PCMCIA cards. All three have the same rectangular size (85.6 by 54 millimeters), but different widths

  • Type I cards can be up to 3.3 mm thick, and are used primarily for adding additional ROM or RAM to a computer.

  • Type II cards can be up to 5.5 mm thick. These cards are often used for modem and fax modem cards.

  • Type III cards can be up to 10.5 mm thick, which is sufficiently large for portable disk drives.

As with the cards, PCMCIA slots also come in three sizes:

  • A Type I slot can hold one Type I card

  • A Type II slot can hold one Type II card or one Type I card

  • A Type III slot can hold one Type III card or any combination of two Type I or II cards.

In general, you can exchange PC Cards on the fly, without rebooting your computer. For example, you can slip in a fax modem card when you want to send a fax and then, when you're done, replace the fax modem card with a memory card.

Racks

A set of components cabled together to communicate between themselves. A rack is a container for an enclosure.

SDRAM

Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM

Server Blade

Typically a very dense server system containing microprocessors, memory, and network connections that can be easily inserted into a rack-mountable enclosure to share power supplies, fans, switches, and other components with other server blades. Server blades tend to be more cost-efficient, faster to deploy, and easier to adapt to growth and change than traditional rack-mounted or tower servers.

SIMM

SIMMs have contacts on either side of the circuit board but they are tied together. So a 30-pin SIMM has 30 contacts on each side of the circuit board, but each pair is connected. This gives some redundancy and allows for more forgiving connections since each pin has two pads. This is also true of 72-pin SIMMs.

Simple Network Management Protocol (SNMP)

One of the management protocols supported by HP Systems Insight Manager. Traditional management protocol used extensively by networking systems and most servers. MIB-2 is the standard information available consistently across all vendors.

SMBIOS

It is responsible for reporting configuration data to diagnostic programs

System

Nodes on the network that communicate through TCP/IP or IPX. To manage a system, some type of management protocol (for example, SNMP, DMI, or WBEM) must be present on the system. Examples of systems include servers, workstations, desktops, portables, routers, switches, hubs, and gateways.

User

A network user with a valid login on the CMS that has been added to HP Systems Insight Manager.
