Can anyone explain the following to me:
Inside the VM the drive shows a usage of 149GB. When I select all folders on that drive I get a total of 5GB.
When I look at the VHDX file on the hosts file system the size is about 5GB - the 5GB pretty much reflect what I copied to that drive over the...
you are everywhere :-) - That is my old thread from 2017. But the topic is actually still valid. I have SSD RAID 6 and was about to use ReFS but am currently struggling with the decision as I have read quite a few post about dataloss with RefS in 2018 - that is really troubling me...
I am starting to doubt ReFS. I have still seen quite some post with bad experience since 2018 which talked about colume corruption with disk being in "raw mode" and no means of repairing it - that would really suck.
Hi I was talking about strip size.
I meanwhile replaced the Braodcom with an Adaptec controller and a srip size of 16kb gave the best overall performance for the file sizes which are most common.
I also moved to IO-Meter for benchmarking as the synthetics weren't helping much and my windows...
Sorry I have somehow missed you post almost 2 years ago. The last PACS worked OK for what it was supposed to do: large volume at lo cost. Performance was ok considering the expectations, but not mind blowing - we ended up with a RAID 10 for 8 6TB HDDs on NTFS with some FS tweak.
Hello dear forum members
I just benched my virtual server and the VHDX which is meant for the file storage isn't performing very well.
The bare metal SSD RAID gets around 515MB/s for files sizes of 256kb and the VM only achieves 439MB/s - IOMeter 100% random read. The smaller the file sizes go...
I tried Raid 50, its the same performance in my real-world copy test - however ATTO is 50 to 100% improvement - it just doesn't ranslate into real-world performance.
Its either the drives can't go any faster even if working on striped files with 64kb stripe size or it is some IO/bandwidth issue...
Well going 3x RAID isn't a financial viable option.
There are some reviews that BBWC isn't helpfu in Ssd based raid however the point in my case is that writes are a non issues - I want to improve random read speed for files below 200 to 300kb in size. From 300kb on random read in real world...
Hi, thx for your reply.
How do I find out the page size of my SSDs? - if it's 4k I can't set the corresponding stripe size anyway as the lowest in Broadcom is 64k and Adaptec 16k.
Going from Raid 6 to 5 is probably not going to bring much as it will only speed up reads from files which are...
I am setting up a RAID for a file server. It is supposed to be a RAID 6 with 9 SSDs and it will replace a RAID 10 with 8 HDDs (7200rpm).
The files we store are pretty small:
10% below 32kb
5% between 32-64kb
60% between 64 - 300kb
25% above 300kb
and like 2 % above 1MB
files are written...
I use a 9460-8i RAID controller. It is connected to a Chenbro SAS Expander with LSI 3x 36 chipset
via 1 MinSAS connector available on the controller.
In Broadcom LSA the connection status says that is connected to the backplane with 4 channels.
I am using 9 SATA SSDs in a RAID 5 and the RAID...
OK, so I am not alone with that issue.
That's good as I was about to question my mental health after I missed the RAID 6 option.
Now I gotta see if I get a Broadcom 9460i or an Adaptec controller
Does the 9460 has Raid 6 out of the box or does it need a license?
