As you can see in this article, especially the picture of the machine, it seems that those machines use standard RAM and have at least on implementation as storage server:As another quick question - do any of the 64 bit ARM systems allow replaceable memory, or is it all SoC? I could see a use for ARM in a server market if the 64 bit models allow regular DDR3 DIMMs or SO-DIMMs - sometimes tasks are very memory demanding but not so CPU demanding. I suppose ARM would also be handy if it were used as a central backup system, assuming some of the server models have bundles of SATA/SAS ports.Gopi also unveiled three server reference designs that AppliedMicro has come up with, to show server makers what they can build. They’re dubbed X-Memory, X-Compute and X-Storage, depending on the target application.
The X-Storage system is aimed at Hadoop-type analytics applications, and combines a sea of hard disks with a single X-Gene server board. It had a total 36TB of storage, Gopi said.
