Thanks for the reply! I understand the appliance is one per vCenter, but do I place the appliance on a host at my primary site or host at my DR site? Thanks for the article, that should work just fine for our purposes.
Ever thought of trying Microsoft clustering for SQL?

Can deploy VMA to backup your host configuration.  Spin up another disk and storage VMotion to it.  Install ESXi on the new disk. Or you can completely backup ESXi and VM's rebuild and restore all from backup.  Either way, best to have redundancy to avoid issues like this.

Shared storage is typically best.  You can take advantage of HA or FT in that scenario.  Performance depends on a lot of different things such as spindle count, workload, disk type, etc...  How is your SAN configured?  A common scenario is run RAID 5 on a tray with a hot spare.  There are many details you need to consider.  Hope that helps.

I'm currently looking into deploying the vSphere Replication Appliance.  We only have a single vCenter at our primary site which manages our DR site as well.  Should I place the appliance in the DR datacenter, or at the Primary Site? As a side question, can I replicate our vCenter with the appliance as well? Thanks in advance!

1 Day - Level 1 2 Hours - Level 1 30 Mins - Level 1 5 Mins - Level 2 Here is the event that's logged: Device naa.6006016033802016fbcac95161e111 performance has deteriorated. I/O latency increased from average value of 7851 microseconds to 329494 microseconds. warning 4/2/2012 12:18:53 PM server.domain.com I did just notice something in the perflogs on the specific host.  Seems the time of the spikes there are a few fibre channel paths with spikes in "Disk SCSI Reservation Conflicts" as well.  Not sure if this has anything to do with the issue we're seeing? Performance frequency in Solarwinds is set to every 5min.
Looking at disk performance in the past 24 hours on both.

We're working on addressing a disk latency spike issue in VMware.  The problem we're seeing is that vCenter reports a latency warning for one of our LUN's at a certain time.  If I check the latency graphs for our SAN at that time, it is different then what is reported in vCenter.  Any reason for this? We're using Solarwinds Storage Manager to monitor our SAN / VMware storage.

Much appreciated.  However in order to use esxtop I need to SSH into a host correct?  I'd like to see the VM statistics per datastore, as it only seems to be a select few datastores.  Just trying to narrow down the culprit.  I'll try to use esxtop for each of our hosts during the spike to see if I can see anything.  Thanks again!
We're currently experiencing several disk latency alarms since upgrading to vCenter 5.0.  It only seems to be for a short period of time in the day.  Was the alarm threshold changed in vCenter 5?... See more...
We're currently experiencing several disk latency alarms since upgrading to vCenter 5.0.  It only seems to be for a short period of time in the day.  Was the alarm threshold changed in vCenter 5? What'd be the recommended way to punch down to find out what is causing the issue?
So next question, should I configure a Standard Switch for each iSCSI port or just a single vSwitch for both ports?
It continues to function, just not able to manage.  Check out this article: http://www.yellow-bricks.com/2011/04/21/distributed-vswitches-go-hybrid-or-go-distributed/
Might it make management easier to use vDS rather than configuring this on each host?  Is there documentation around setting this up on vDS?
Is it better to use Standard Switches or vDS switches for iSCSI VMKernel ports?  Which is the better route to go? Is there documentation outlining the process somewhere?
