VMware is working on a software-defined memory effort and thinks it could lead to the creation of "memory servers" – boxes full of memory that can be shared across a cluster.
DRAM can account for 40 per cent or more of a server's cost, but remains expensive. Memory is also in demand, as more workloads require in-memory processing. VMware's customers tell the company that access to memory is a bottleneck more often than access to I/O or storage.
VMware has also noticed that memory seems to be the last item of hardware that hasn't been virtualised. The company considers forms of memory other than DRAM to be under-utilised by applications. In Virtzilla's view that's because today, software vendors need to write their own code to take advantage of different memory tiers.

VMWare kehittää muistiservereitä. Tälläisillä koneille voitaisiin laittaa muistit. Latenssit ovat kuitenkin ongelmana, koska tieto liikkuu valonnopeudella etäisyys vie aikaa. Monessa asiassa nimenomaan muisti on pullonkaula. Muistiservereillä olisi helppo lisätä muistia keskitetysti.
