Data Locality matters... a LOT! See this video demo.

Nutanix utilizes a shared-nothing distributed architecture and it ensures data is always replicated across Flash, HDD, Nodes and Blocks for high availability. A VM may access data from anywhere on a Nutanix cluster, but Nutanix controllers (CVM) will always ensure that overtime active data blocks that belong to a VM are present in the host where the VM is currently running. This process is transparent and occurs in the background using free CPU cycles.

Disk Latency (another Case Study)

After the feedback on my recent post Host Swapping (another Case Study) I decided to share some more real world troubleshooting scenario. In this case study a small VDI cluster (VMware View) with approximately 120 virtual desktops and 6 hosts (average of 20 VMs per host at this stage). Users were complaining of slow performance at some moments of the day.

VKernel released new tool for troubleshooting NFS I/O

As you probably know, vCenter does not give you any visibility into VMs running on NFS. Troubleshooting performance issues on NFS has been all but impossible -- until now.
VKernel engineers figured out how to get visibility into NFS I/O and enhanced Capacity Analyzer with this capability.
