Manageability
Powerful systems management features simplify local and remote management of the x3550:
• The x3550 includes a Baseboard Management Controller (BMC) to monitor server
availability, perform Predictive Failure Analysis, etc., and trigger IBM Director alerts. The BMC
enables service personnel to use sophisticated diagnostic tools, such as light path
diagnostics, to resolve problems quickly.
• Integrated IPMI 2.0 support alerts IBM Director to anomalous environmental factors, such as
voltage and thermal conditions. It also supports
highly secure remote power control using
data encryption.
• IBM Systems Director Active Energy Manager for x86, an IBM-exclusive, is designed to
take advantage of new system power management features, by providing power monitoring
and power capping features.
• Text Console Redirection support allows the administrator to remotely view x3550 text
messages over Serial or LAN.
• IBM Director is included for proactive systems management and works with both the blade’s
internal BMC and the chassis’ management module. IBM Director comes with a portfolio of
tools, including Management Processor Assistant, Rack Manager, RAID Manager, Update
Assistant and Software Distribution. In addition, IBM Director offers extended systems
management tools for additional server management and increased availability. When a
problem is encountered, IBM Director can issue administrator alerts via e-mail, pager, and
other methods.
• An optional Remote Supervisor Adapter II SlimLine provides additional systems
management capabilities, including Web-based out-of-band control; virtual floppy and optical
drive support; Windows “blue screen” error capture; LDAP and SSL support; and remote
redirection of PCI video, text, keyboard and mouse. And it does all this without consuming a
valuable adapter slot.
Availability and Serviceability
The x3550 provides many features to simplify serviceability and increase system uptime:
• x3550 servers use Chipkill-enabled fully buffered memory DIMMs. Chipkill memory is up to
16X better than standard ECC memory at correcting memory errors. This can help reduce
downtime caused by memory errors.
Fully buffered DIMMs provide additional availability
features, including CRC (cyclic redundancy check) monitoring.
• The x3550 offers selectable online hot-spare memory and memory mirroring for
redundancy in the event of a noncorrectable memory failure
• Toolless cover removal provides easy access to upgrades and serviceable parts. Similarly,
the
Remote Supervisor Adapter II SlimLine and the ServeRAID-8k controller can be
installed and replaced without tools. This means less time (and therefore less money) spent
servicing the x3550. Similarly,
hot-swap/redundant HDDs, fans and power supplies, as
well as
online hot-spare and mirrored memory, mean greater system uptime while these
components are being serviced.
• New toolless slides ship with the server, together with a Cable Management Arm (CMA),
that allows the rack server to easily slide into place
• IBM Thermal Diagnostics allows the administrator to evaluate thermal data on the server
without taking the hardware offline. This can provide greater server uptime.
• The drop-down light path diagnostics panel and individual light path LEDs quickly lead the
technician to failed (or failing) components. This simplifies servicing, speeds up problem
resolution and helps improve network availability.
• Integrated RAID-1 disk mirroring and RAID-10 striped mirrored arrays standard enable
the server to keep operating in the event of a failure to any one drive.
• IPMI 2.0 supports highly secure remote system power control using data encryption. This
allows an administrator to restart a server without having to visit it in person, saving travel time
and getting the server back up and running quickly and securely. It also adds new features to
those provided by IPMI 1.5, including
VLAN support, Serial over LAN, enhanced
authentication and encryption algorithms (
RMCP+, SHA-1, AES) and a firmware firewall.
• Temperature-controlled fans adjust to compensate for changing thermal characteristics. At
the lower speeds they draw less power and suffer less wear. Equally important in a crowded
data center, temperature-controlled fans produce less ambient noise in the data center than if
