Where are ROW modes in V8?

Subject line pretty much says it all. I'm trying to figure out how you can configure a disk in redirect-on-write mode like existed in V6. Does V8 add the ability to store such a disk in RAM? I talked a bit about ROW functionality related to V6 here, and was told to wait. V8 seems to not include it a...

Re: Move to a supported OS and performance goes down the tubes?

I haven't asked MS yet, but I'm not sure what help they could give. That phase of bootup isn't logged very well, and likely couldn't be logged at all in ROW with discard mode, which is what I use.

Re: Move to a supported OS and performance goes down the tubes?

I should probably clarify my thread title. "Throughput performance" doesn't appear to be the issue. "Bootup performance", on the other hand, is what has suffered. I get great throughput. It appears to be roughly the same as when Win7 Pro was the host OS on the target server. What...

Re: Move to a supported OS and performance goes down the tubes?

I still haven't found any good explanation for this. I have noticed, however, that when systems are delayed in the boot process, it's during the switchover from the iPXE boot ROM to the MS initiator. I'm combing through Starwind log files to see if I can find good examples and track down why those e...

Re: Move to a supported OS and performance goes down the tubes?

I haven't found any parameter that makes it flakey in terms of the number of machines it will allow to connect to the target and boot simultaneously. The parameter changes only change the performance of a session after it's connected.

Re: Move to a supported OS and performance goes down the tubes?

So far, in my testing, I've found that the stickied forum post about TCP/IP tuning should probably be permanently deleted. :shock: In my environment, at least, modifying ECN, chimney, jumbo frames, and similar parameters per the doc are a sure-fire way to have poor performance in Starwind. I get muc...

Re: Move to a supported OS and performance goes down the tubes?

The NIC driver (downloaded from Intel), was the same version for both OS'. I have tried enabling all of the jumbo frame, chimney, ecn, and so on...options as recommended in the forum post here. Nothing has made a difference so far. Nothing I've done makes performance go back to what it was when Win7...

Move to a supported OS and performance goes down the tubes?

I've been running a CDP target in ROW mode off of a Win7 test machine for a while now. I have an Intel 10Gbps NIC in this machine, and I have 30-50 machines booting up off of that ROW target simultaneously. I used to store the image files on flash storage, but have since moved them to a ramdisk to i...

Re: ROW targets using something other than Snapshot/CDP

Glad to hear I'm not the 100th person to ask for this. :)

I'm ready to test when you are.

ROW targets using something other than Snapshot/CDP

I've been working more with ROW targets, and I'm coming across a fair amount of pain any time I want to update the CDP golden image. Seems like there isn't anything I can do to eliminate the creation of a snapshot when I have the CDP device mounted in growing mode. This makes for quite a bit of wast...

Re: Sharing a single target to EWF-protected Windows initiators

Shouldn't converting from IMG also work? What did our QA team do EXACTLY? digitalis99, Please, try to install Windows directly on IBV Growing Image -- skip the steps concerned with ImageFile device. And then go to the ROW mode. I already tried both methods, neither worked. I can boot off of the tar...

Re: Sharing a single target to EWF-protected Windows initiators

Works absolutely brilliant here. Can you provide a logs so we'd see you did install recent build and doing what you're supposed to do? Also tomorrow guys will provide step-by-step guide on what WE did here (just to figure out what's different from your side). I don't know how much of log you want t...

digitalis99, You can download last build of StarWind here: http://starwindsoftware.com/tmplink/StarWind_6.0_20120927.exe Waiting for your response! Ahh...not impressed so far. Installed this build and Windows booting from the target errors out with exact same error message as before (failure to fin...
