IBM System Storage DR550
Version 3.0 ------17 March 2006
Page 9
Additional features are designed into pSeries servers to provide an extensive set of reliability,
availability, and serviceability (RAS) features such as improved fault isolation, recovery from errors
without stopping the system, avoidance of recurring failures, and predictive failure analysis.
Additional information on the P5 520 server is available at www.ibm.com/redbooks.
Management Console
Included in the DR550 is a set of integrated management components. This includes the Hardware
Management Console (HMC) as well as a flat panel monitor, keyboard and mouse. The HMC
(7310-CR3) is a dedicated rack-mounted workstation that allows the user to configure and manage
call home support. The HMC has other capabilities (partitioning, Capacity on Demand) that are not
used in the DR550. The HMC includes the management application used to setup call home. To
help ensure console functionality, the HMC is not available as a general purpose computing
resource. The HMC offers a service focal point for the 520 server(s) that are attached. It is
connected to a dedicated port on the service processor of the POWER5 system via an Ethernet
connection. Tools are included for problem determination and service support, such as call-home
and error log notification, through the internet or via modem. The customer will need to supply the
connection to the network or phone system. The HMC is connected to the keyboard, mouse and
monitor installed in the rack.
The IBM 7316-TF3 is a rack-mounted flat panel console kit consisting of a 17 inch (337.9 mm x
270.3 mm) flat panel color monitor, rack keyboard tray, IBM travel keyboard (English only), and the
Netbay LCM switch. This is packaged as a 1U kit and is mounted in the rack along with the other
DR550 components. The Netbay LCM Switch is mounted in the same rack space, located behind
the flat panel monitor. The IBM Travel Keyboard is configured for English. An integrated "mouse" is
included in the keyboard. The HMC and the P5 520 servers are connected to the Netbay LCM
switch so that the monitor and keyboard can access all three servers.
IBM TotalStorage DS4100 Midrange Disk System and IBM TotalStorage
DS4000 EXP100
The DR550 includes one IBM TotalStorage DS4100 Midrange Disk System (hereafter referred to as
the DS4100) in DR550 configurations of 44.8 TBs or less. With 89.6 TB configurations, two
DS4100s are included. The disk capacity used by the DS4100(s) is provided by the IBM
TotalStorage EXP100 (hereafter referred to as the EXP100). Each EXP100 enclosure packaged
with the DR550 includes fourteen 400 GB Serial ATA (SATA) disk drive modules, offering 5.6
Terabytes (TB) of raw physical capacity.
The DS4100 is an affordable, scalable storage server for clustering applications such as the Data
Retention application. Its modular architecture —which includes Dynamic Capacity Expansion and
Dynamic Volume Expansion—is designed to support e-business on demand™ environments by
helping to enable storage to grow as demands increase. Autonomic features such as online
firmware upgrades also help enhance the system's usability.
One DS4100 supports up to 44.8TB of Serial ATA physical disk storage capacity (seven EXP100
enclosures). Thus for 89.6 TB configurations of the DR550, dual DS4100s are provided, each
capable of supporting up to 44.8 TBs of raw disk capacity. Note, the first rack holds the first 44.8 TB
and the second rack holds the second 44.8 TB.
The DS4100 is designed to allow upgrades while keeping data intact, helping to minimize
disruptions during upgrades. The DS4100 also supports online controller firmware upgrades, to help
