Hi Philip,
Evan Powell, Nexenta's CEO were recently bloging about the so called
Delorean project - a Time Machine for Windows:

He says:
‘Delorean’ is intended to allow time travel for windows users by

Could you try to set the IO scheduler to noop:
echo noop /sys/block/sdX/queue/scheduler
and see if that makes a difference?

I would recommend to isolate Networking first. I.e. run iperf between
the boxes (Linux vs. OpenSolaris), single thread, 512 bytes payload -
this will somewhat emulate iSCSI traffic over single raw device. See
what you'll get...

It appears that osol is having a little trouble transmitting information.

Hi Roman,
take a look on what NexentaStor is providing:
auto-cdp - a commercial plugin which simplifies significantly ZFS/AVS
management of primary/secondary hosts
auto-sync - a free service which supports sophisticated ZFS send/recv
over SSH, NC. Or use send snapshots over RSYNC - which
All public plugins CDDL licensed, however they really depends on NMS and
component APIs. More public plugins coming soon such us: UPS and
ClamAV/ZFS - but also, this website can host projects which are related
to OpenSolaris / Nexenta, such as kernel gate:
BTW, there are two commercial plugins for NexentaStor as well which will
solve HA problem nicely in my opinion:

1. Simple-Failover plugin - active / passive manual failover
2. HA Cluster
Its available actually for NexentaStor/OpenSolaris as a separate plugin.
It supports remote API, FC and iSCSI targets:

Guys,
just to let you know that Nexenta was working for quite some time on its
COMSTAR VTape driver. It is now beta ready and feature complete as far
as code is concerned:

It requires b131+ to compile and run. Tested with NexentaStor and with

Hello Erast,
This could well be the same as a bug that was logged:
6553970 VMware Workstation 5.5.4/6.0beta choked when
booting snv_63 or s10u4_06
So you may want to talk VMware about this.
I have tried b65 on build 6.0.0

If you do ZFS snapshots of VMs, you need to quiesce VM states first.
This can not be done without serious integration with ESX servers. And
