Hi guys! I'm interested on having L1 cache on disk instead of RAM, because I have seen L1 cache writes back data at a slower rate than direct ones. My data storage is a slow RAID6, and when writing big ammounts of data, IO reads experiment a very high latency. The only way I found to increase read s...

Sorry, too busy on these days.

I shall not be able to repeat tests until a few weeks...

Hi Josip, Thanks for your reply, aame conclussion here!. Sequential write performance also is increased when using hyperconverged scenario using iSCSI connections to local private IPs (i.e 192.168.x.x, not 127.0.0.1 ). I think the problem is related to loopback acceleration, either of the Starwind s...

Hi all! During a few tests with a new replica configuration I have found a serious issue involving sequential writes with outstanding operations. I have used Starwind Virtual SAN v8.0.8730 on W2012R2 Here are my results using CrystalDiskMark. Note that the Sequential Write (Q= 32,T= 1) IO test is 12...

Hi guys! I started testing v8.0.792 a few days ago. In my tests, I have noted when I create an high availability volume, deduplication on replica is enabled by default although it shows "Deduplication=no" on Starwind console. I have edited .swdsk file of the volume on both nodes and I have...

Same here, when using LSFS volume, L2 cache appears disabled and when creating thick volume, it does not appear anyway.

When upgrading from build 6884, contents of a volume previously created using L2 cache have dissapeared!!!!!
