Specifications

The interlock is a safety feature that is used when more than one product is to be installed in a single

rack. This feature works only when two products are mounted on slides adjacent to each other (above

and below) in a rack. The function of the anti-lock mechanism is to prevent sliding of more than one

server from the rack at any given time. In the absence of this mechanism, if two servers are pulled out

at the same time, the rack can tip over.

For stability during servicing, ballast kits are used on HP cabinets in which the HP 9000 rp7440 or

rp8440 Servers are installed. The ballast weight base mount is designed to counteract the movement

of one product in an HP RBII rack when extended out on its slides for servicing. The ballast weight

also works in conjunction with the interlock mechanism to counteract the movement of one or two

products in an HP RBII rack being extended for servicing. Every system that HP ships, excluding

pedestal models, includes a ballast kit. The ballast weight easily attaches to the rear anti-tip foot that

comes standard with every HP Rack System cabinet. Use of the ballast kit is mandatory for safety and

for warranty validation, and the kit should be installed immediately.

Also included with every HP 9000 rp7440 and rp8440 Server is a cable management arm (CMA).

The cable management arm is a two-member trough system that resides at the back of the chassis and

guides cables during extension and retraction of the product. The CMA neatly secures data cables

and prevents them from becoming entangled while the system is being serviced.

Third-party racks

HP servers are designed to maximize performance density when installed into HP system cabinets.

Moreover, HP system cabinets maintain the high level of safety and reliability that you have come to

expect. Although HP strongly recommends racking in HP cabinets, some circumstances might prohibit

this. Therefore, HP has developed guidelines that enable safe, reliable HP server installations in third-

party cabinets. Because of the wide variety of cabinets in the marketplace, it is extremely important

that the guidelines be followed explicitly. See Chapter 4 in the HP Server Configuration Guide for the

racking guidelines.

Server virtualization

Virtualization means that the physical resources are separated from the logical view of the server

infrastructure. Server virtualization helps administrators to improve the usage and simplify the

management of single or multiple server environments by configuring them as reusable pools of

resources. The HP Virtual Server Environment (VSE) for the HP 9000 rp7440 and rp8440 Servers

does just that—sharing, pooling, and allocating of server resources to optimizing utilization, adapting

to changing IT needs while driving down cost.

With the HP VSE, you can increase your utilization of the HP 9000 rp7440 and rp8440 Servers,

maintain nearly continuous service levels, and pay for only what you use. The HP VSE consists of tools

for intelligent control, features, and tools for partitioning the server and availability and provides the

flexibility of utility pricing.

The HP 9000 rp7440 and rp8440 Servers and the HP VSE offers the broadest range of hard and

virtual partitioning solutions in the industry to provide data center security and uptime, while

simultaneously maintaining the highest degree of flexibility. Resource virtualization can be done at the

server, hard partition, or soft partition level. The two strategies for partitioning available to you are

hard partitioning (nPars) and virtual partitioning (vPars). Each partitioning strategy splits the resources

in the server (processors, memory, and I/O) into instances that can each run an operating system

instance.
