IBM System x3850 X5 review

The latest System x3850 X5 offers an expansion potential that defies belief. In this exclusive review we bring you the first look at IBM’s new Xeon 7500 rack server.

The IMM allows you to monitor critical components, remotely control power and run unattended firmware upgrades. You also get full KVM-over-IP remote control, virtual boot media and an OS failure blue screen capture function.

IBM's Systems Director handles general systems management and is accessed via a tidy web interface packed with plenty of wizards. You can run network discoveries, collect and store hardware and software inventories and use its problem alerting system.

The results of the network discoveries are viewed from the Systems Director home page and options are provided for deploying agents to IBM and non-IBM systems. These allow you to collect inventory data, execute tasks such as file transfers and run remote control sessions using RDP or RealVNC.

All power management features are handled by the Active Energy Manager plug-in. This interacts with the server's IMM and provides power capping functions along with trend graphs of power consumption and system temperatures over time.

The x3850 X5 is an impressive rack server offering a lot of classy features in a compact chassis. IBM's unique expansion options are not all available yet but, even without FlexNode support, the x3850 X5 still offers an unprecedented potential that is unmatched by any other Xeon 7500 server currently available.


The System x3850 X5 costs significantly more than a similarly specified Dell PowerEdge R910 but is its equal for features and beats it hands down for expansion potential. The ability to expand memory beyond 1TB and to link two servers together and present them as a single node makes it quite unique although note that IBM’s FlexNode feature is not currently available.
