Also included with every Integrity rx7620-16 and rx8620-32 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 customers have
come to expect. Although HP strongly recommends racking in HP cabinets, we recognize that some
customer circumstances may 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
Server virtualization helps administrators to optimize the usage and simplify the management of
single- or multiple-server environments by configuring them as reusable pools of resources.
Virtualization means that the physical resources are separated from the logical view of the server
infrastructure. A number of solutions for vertically scaled environments are available from HP for the
HP Integrity rx7620-16 and rx8620-32 Servers.
Vertical scaling typically means the use of a few consolidated high-performance servers to run many
concurrent complex applications. This environment offers major opportunities for cost reduction and
better utilization of existing assets. HP solutions for server partitioning and resource optimization can
help administrators drive server utilization from a typical 15–50% to over 90% without service-level
degradation. The combination of a virtualized server environment with HP Utility Pricing Solutions
such as Instant Capacity and Pay per use (PPU) allows customers to activate additional capacity only
when it is needed and to make payments for server resources based on actual usage.
The HP Partitioning Continuum provides a range of hard, virtual, and resource partitioning tools that
offer resource virtualization at the server or partition level, improve overall system and subsystem
utilization, and lower costs in consolidated environments. Partitions are physical or logical
mechanisms for isolating operational environments within single or multiple servers. Partitioning
provides IT managers with the flexibility of dynamically resizing an application’s resource usage while
making sure that all applications enjoy protection from disruptive events that could cause service
interruption or performance degradation. The HP Integrity rx7620-16 and rx8620-32 Servers both
offer the same mainframe-style partitioning capability. When coupled with the HP-UX operating
environment, partitions in the HP Integrity rx7620-16 and rx8620-32 Servers allow a single system to
be logically divided into multiple independent systems within the same server.
nPartitions
Hard partitions in the Integrity rx7620-16 and rx8620-32 Servers are referred to as nPartitions
(nPars). The “n” indicates that a partition actually has a wide number of functions that it can perform.
These nPartitions provide a degree of isolation that can be utilized to consolidate several applications
on a single server, give flexibility in resource management, and deliver improved availability and
scalability.
