Almost one month ago, immediately after the VMware Partner Exchange conference, TechTarget published a scoop about some new features that may appear in the upcoming version of vSphere, expected later this year.
The list includes:
- Transparent Memory Compression
This will avoid swap when RAM is overcommited by compressing a set of target pages to a special region. VMware measured the latency of this technique as a hundred times better than the latency of swapping on rotating disks.
- IO-Resource Manager (IO-RM)
This will allow the Distributed Resource Scheduler (DRS) to assign shares based on disk performance. The more shares a virtual machine will have, the higher priority it will get in accessing a shared VMFS volume.
- Eight concurrent live migrations
Next version of VMotion will raise the default limit of concurrent live migrations from two to eight.
