"Hol olvastál/hallottál erről a felső határról?"
Őőőő... Ártatlan vagyok! Csak megnyitottam a linket, amit a cikkben az eX5-ről beküldtél, ott megnyomtam a "Read More" feliratot, és ott az oldal alján a számozott megjegyzések:

"2. The maximum amount of memory for the current generation IBM system is 256GB. The new eX5 version with MAX5 attached is 1536GB, which is six times more memory."
"4. IBM will offer a two-socket eX5 system with MAX5 and 64 dimms capable of supporting 320 virtual machines. Users of competitive systems would have to purchase a four-socket system to support a comparable amount of virtual machines and pay 50 percent more licensing costs. Based on sizing information performed in the IBM performance lab.
5. Comparison of a competitive two-socket system with 18 dimms capable of supporting 175 virtual machines vs. an IBM two-socket eX5 system with MAX5 and 64 dimms capable of supporting 320 virtual machines. Based on sizing information performed in the IBM performance lab."
Azt már nem tudom miből gondoltam, hogy egy pengére is ráfér 64 dimm slot. De végülis... Ha a vinyó kimarad, az rettenet sok hely! ;-)
Azt meg lehet FC-vel, iSCSI-val,FCoE-vel, stb. pótolni.
