Re: VM Performance during full sync

Hi Max, - Thanks for clarification. 1. I hear you, but when desired performance level is to continue to run one VM, doing nothing, all i've tried to do is open the start menu - takes 30 seconds, and a sync that isnt even saturating a 1gbe connection when we have an 8 disk Raid 10 array on a 512mb b...

Re: HA heartbeat

When I create a HA disk, the dropdown for Heartbeat just says 'none'. There are 4 IPs in the sync dropdown so why is heartbeat empty? It allows me to create the disk even without a heartbeat though. Thanks. Just press refresh button (green one in the right side of "heartbeat interface") a...

Re: Starwind iSCSI vs Microsoft NFS

Understood. I will run the tests as soon as I can and post the results. In the mean time, I have a dumb question and I can't find the answer anywhere on Starwind's site. I own a license of Starwind and I'm still within my 1 year maintenance agreement. What web page do I go to to see what the curren...

Re: Starwind iSCSI vs Microsoft NFS

Ok, it is good that you know that your network can go faster but I need numbers I can refer to. It takes maximum 5mn to test it using NTTtcp or iPerf... And test results for RAM device using ATTO in Direct I/O, overlapped I/O with maximum queue depth. For your Disk bridge device, try to create it wi...

Re: Starwind iSCSI vs Microsoft NFS

By the way, you are using cache size assigned by default in StarWind Console, try to have more cache in write-back mode: 512Mb for example.

Re: Starwind iSCSI vs Microsoft NFS

Since you are noticing the difference of performance when using "Disk Bridge" you should first check the performance of your network link between your StarWind server and your ESX server, if you will get the full bandwidth your link can give you can go further and test RAM device, create a...

Re: ESXi iSCSI initiator WRITE speed

Hi, What is the stripe size used for your RAIDs? Did you applied the recommended setting for ESX iSCSI initiator?

Re: Where are the syncronization logs?

Thank you for your reply. I've looked in the location you mentioned and it doesn't have anything useful. By looking at the ARECA Raid Controller logs I can tell exactly how long it takes to rebuild a Raid or Volume. Do you think this is something you could add to some future version? Also, I realiz...

Re: Where are the syncronization logs?

We are trying to determine what size to make our LUNS to keep from being down for days at a time during a syncronization. I have inherited this entire system/setup and am unable to find anything that will tell me how long it has taken to syncronize in the past. Could someone be kind enough to point...

Re: Horrible Sequential write performance

Any ideas? This thing is running terrible and we have had to move most of our VM's out of it. Your tests results show bad performance only from VM on HA and mainly with 256 sequential write, from clusters hosts you get good results. This problem is related to disk alignment. Support team will conta...

Re: Problems with Primary Target shortly after upgrade to 5.6

Is the roll back to 5.5 as simple as stopping the service on one side, installing 5.5 and re-synching? Will 5.5 install on top of 5.6 or do you have to uninstall first? Thanks! It can be installed on top. Install on one side, sync, then install on second side and sync. Yep, this is what I did. It d...

Re: Problems with Primary Target shortly after upgrade to 5.6

As the title suggests I am having some issues about a week into the upgrade of 5.6. All of a sudden when my primary is online none of my VM's will respond that are on the iSCSI. As soon as I shutdown the primary and the partner takes over everything works great. My partner can't run everything very...
