Hi, thanks for the reply. Yes, i think upgrading would be a good idea too :-) I am not using Starwind in an HA configuration. It is just one physical box at the moment. I just need to basically move all the img files off the server, wipe it and rebuild the server from scratch then copy the img files...

that should be starwind version 5.eight (but it put a smiley in instead of the eight!)

Hi, I am going through the process of coming up with a plan to move my starwind server over to RAID50 from RAID10 and unfortunately my RAID card wont allow me to do this on the fly so I am going to have to reinstall windows and Starwind (I am on version 5.8). I have 4ximg files (all quite big) and I...

Dear Starwind Team, I have a quickk question about SAN luns in a vmware vsphere environment. The reason I ask is because I have an issue with my Dell Equallogic with a particular issue and wondered if the same applies to Starwind. Basically it all centres around free/used space on a VMFS volume. If ...

Ok guys, well I finally got to the bottom of it. I will post the resolution in case anyone else out there has issues with nortel/avaya switches... The nortel/avaya switches buffers are linked to each group of 12 ports. By default each port is only allowed to use up to 33% of the buffer. This has to ...

Right,

issue is to do with our Avaya/nortel switches. 10k's worth of switches in a stack and a netgear out performs it!

I am looking in to this issue now.

thanks,

Paul

Hi, Saw your message on my post on the vmware forums. I am still investigating but essentially I seem to be getting somewhere now. I have built a new ESXi5 server, set up round robin and linked it to the starwind SAN. I have moved this set up off my Avaya switches and done some performance testing u...

just a quick update: I have not tried the direct connection yet as I have some vm's in use on the equallogic. But.... I have stopped starwind and installed the microsoft iscsi target and tested that out. Still no better so this is def not a software san issue. I updated the onboard broadcom nics and...

hiya,

yes EQL has jumbo frames enabled. All good on that front

I will try the direct connection. Just need to find some straight throughs....

Hiya, What I mean is: In round robin I see about 10-30% network utilization on each nic on the starwind server (iometer shows 40-60mbps on sequnetial read) in fixed path using one link I see 90%+ (110mbps on sequential read in iometer) I have spent a lot of time on this, messing around with the inte...

well, one thing that was an issue was that I was using a broadcom nic on the ESXi host for one of my vmknics on the iscsi switch doh! (this may/may not have been a problem) I rebuilt it correctly now so that all the nics on both the starwind server and ESXi are using the intel nics. I am still getti...

Hi again, I tested out both links seperately on fixed and they are both fine. Its very strange. When i use round robin if I used the default path policy in VMware with 1000 iops I see around 108mbps across both links. If I change the policy to 1,2,5,10 iops it drops to around 40mbps. I have followed...

good call Anatoly!

I will try that this evening....

Hi Paul, Could you please tell me what were the tests you performed in IOmeter: writes, reads, or both? Which of them shows the degradation if MPIO is enabled? Also, have you already disabled the delayed ACKs? Hi Max, The iometer tests I used were from the unofficial storage performance thread on v...

sorry just posted at the same time as you!, will answer your questions in a sec Hi, Is there any more information I can give to get some help withi this?: some more info if it helps: the nics I am using on the starwind server are Intel and I have updated to the latest drivers. I have 12x2TB sata dri...
