System x is a line ofx86servers produced byIBM, and later byLenovo, as a sub-brand of IBM'sSystem brand, alongsideIBM Power Systems,IBM System z andIBM System Storage. In addition, IBM System x was the main component of theIBM System Cluster 1350 solution.
In January 2014, IBM announced the sale of its x86 server business to Lenovo for $2.3 billion, in a sale completed October 1, 2014.[1][2]
Starting out with thePS/2 Server, then theIBM PC Server, rebrandedNetfinity, theneServer xSeries and finally System x, these servers are distinguished by being based onoff-the-shelfx86CPUs; IBM positioned them as their "low end" or "entry" offering compared to their POWER and Mainframe products.Previously IBM servers based onAMDOpteron CPUs did not share thexSeries brand; instead they fell directly under theeServer umbrella. However, later[when?] AMD Opteron-based servers did fall under the System x brand.[citation needed]
1998–2001 server line; Not to be confused with a software IBM product with a similar name,NetFinity (notice the capital F).
The numbering scheme started off similar to that of the IBM PC Servers, but additional ranges were added, like the entry-level 1000 model later on. Models ending with an R, are rack-mount.
Some Netfinity servers used IBM'sC2T cabling scheme for Keyboard/Video/Mouse.
IBM eServer was a marketing effort to put all of the diverse IBM server platforms under one header. The AS/400 became theIBM eServer iSeries, the RS/6000 became theIBM eServer pSeries, the S/390 mainframe became theIBM eServer zSeries and the Intel processor based IBM Netfinity servers became the IBM eServer xSeries.
A few exceptions were however made
For marketing reasons the AMD processor based e325, e326 and e326m and the BladeCenter which supports non-Intel processor products were not branded xSeries, but were instead placed directly under the eServer brand. The xSeries brand was limited to only Intel-based server products.
From a numbering perspective the AMD servers did fit into the xSeries range, under the similar x335 and x336 Intel processor products. These numbers were not re-used in the xSeries range to prevent confusion.

While most servers used Intel x86 (IA32) processors, the x380, x382, x450 and x455 used theIntel Itanium (IA64) processor.
Many xSeries servers used IBM'sC2T cabling scheme for Keyboard/Video/Mouse.
These systems are effectively the same as the previous IBM branded models, but with a Lenovo badge.
Lenovo also had its ownThinkServer family of Intel servers. This family is technically less advanced than System x. At the time of this writing, System x is being discontinued and replaced by the Lenovo ThinkSystem family of Intel servers.

2nd digit increments to show capability
3rd digit is a 0 for tower models, and 5 for rack-mount
4th digit is a 0 for Intel processors, and 5 for AMD Opteron.
Models with a T at the end are meant for Telco purposes.

IBM System x iDataPlex, introduced in 2008, was used by manyTOP500 supercomputers (as part ofIBM Intelligent Cluster), includingSuperMUC,Yellowstone andStampede. Other smaller installations includedSciNet Consortium's General Purpose Cluster[9][10][11]
It is an unusual form-factor in that you have two columns of 19" rack servers side-by-side in a single rack. This rack, unlike traditional racks, however was very shallow which is where the space saving came from for large installations. As such it only supports specially designed shallow servers. It was typically deployed in combination with a Rear Door Heat Exchanger (RDHx) to cool the exhaust heat with water.
It was replaced withIBM NeXtScale in 2014.
iDataPlex could be ordered as preconfigured rack tower (System x iDataPlex Rack with optional Rack management appliance),[12] or as independent nodes.
iDataPlex 100U rack[13][14] — compact dual rack ((1200x600mm footprint — instead of standard 1280x1050 (2x 42U rack))
Chassis also compatible with standard racks (with another rails).
