Question

VMware ESX and NFS problems

Asked by: nibowl

I have recently setup a VMware ESX 3.5 environment consisting of two hosts.  They have an NFS Datastore that is served up via NFS from a physical Linux server with a RAID 10 of 4 1 TB SATA drives. Each of the VM's (4 total) also connect to an NFS share off of the same RAID 10 (though on a different LVM logical volume).  The VM's are all RHEL 5 as well as the NFS server.

I can scp files between VM's at 20-30 MB/s, scp files from the Datastore (VM's local storage) to the NFS mount at 20-30 MB/s and back again at the same speed.  I can scp files back and forth to the NFS server directly at 20-30 MB/s.  I can dd if=/dev/zero at greater than 100 MB/s to either the Datastore or the NFS mount.  However, if I dd if=/dev/urandom it pegs out at a max of roughly 5-6 MB/s.  The same occurs with the dd using urandom to an NFS volume on a 0 NetApp filer as well from the same VM's.  With the VM that has 4 vCPU's and 24 GB or RAM all of those 20-30's go up to about 60 MB/s but no higher.

It seems that anything actually generating new non-zero data hits a wall.

dd with /dev/zero to NFS mount:

It's not an NFS problem, it's actually a limitation on the CPU.

/dev/urandom generate a new random number for every byte you are trying to write.

So, with 5 MB / second, your CPU is literally dying trying to get some air.  That's a lot of rand() calls.

I wanted to see how fast my computer can churn out random numbers, turns out i'm averaging between 3-4 MB as well.  This is just local operation, nothing to do with NFS / network.

I went back to check to see what I produced doing the same operations as you have in your example and this is what I received (the cpu usage never went below 55% idle and the actual writes were sporadic):

cat /dev/urandom >> test.txt &

iostat -x 1 >> test2.txt (i wasn't sure which device to use at first so i looked at all of them)
