Thanks, I have given up my attempt with ESX. No matter how many VMKernels I make and no matter if they are different networks the maximum speed in iscsi is just 1 to 2 gbit/s I have the same problem with a Windows VM and Starwind on it. So I will wait for NVME-of for CVM and hope that this works und...

That's strange given the Broadcom moves and the "end" of Free ESXi. Microsoft also no longer offers Hyper-V free of charge since Server 2022. either I only use Server 2019 or switch to vmware where I have NFR keys. It is. Try using more iSCSI sessions, i.e., try using more VMkernels, and ...

Hello, I am currently considering switching from my current Hyper-V setup with vSAN Free to ESX. Unfortunately, Hyper-V does not make sense for a home lab in the long term because the trial versions expire and a license costs a lot of money. Since I have access to NFR licenses of vSphere via the com...

Hi, I got it! i added a second sync adapter (used the management) and now the perfromance is doubled. looks like the Sync use only 5 to 6gbits. when i have only one sync adapter it never goes over 6Gbits, now with two adapter, both use 6Gbits. I think i have to buy 25Gbit Cards or use both direct co...

Hi, That's interesting. Thanks for sharing! Can you try multiple iSCSI sessions to the target when replication is enabled? Can you try performance tests with a single sync adapter? Also, can you try iSER for sync links? what you mean with multiple iSCSI session to the target? i have in the iscsi in...

Jan, Please make sure to have the BIOS performance profile set to high performance. Try varying the ratio of read/write cache. Do you see CPU overutilization during the test? Try using Round Robin with a subset where most of the paths use partner connections (then repeat for local-only). Will be wa...

hi, have tested the CSV Volume: Screenshot 2024-01-19 174827.png and here testing the vsan Volume with the image files: Screenshot 2024-01-19 175311.png for vsan the server are connected directly with 2x 10gbit an Jumbo Frames. one link for Sync an one for iSCSI. Management and VM Traffic runs over ...

Hello sorry, unfortunately it took a little longer to try it out. I have made a few adjustments but am not at all satisfied. performance Node1 directly to the RAID50: perfromance_node1.png perfromance Node2 directly to RAID50 is the same because same HW Model, Same Controller and Same SSD performanc...

Hello, 2-node cluster: HPE DL360 G9 P440ar RAID controller with 2GB cache and battery 6x 1TB SSD in RAID5 and 64K strip size Formatted with 64K and NTFS Windows Server 2022 Performance node 1 directly to the RAID volume: Performance_Node1_Direct_RAID.jpg Performance Node 2 directly to the RAID Volum...

I have created 2 volumes on the HPE raid controller on the RAID5. one I have attached directly to the CVM as in the guide the other directly on the host and then run Crystaldiskmark.

I did not specify an HA partner for the CVM test.

Hi, all right thanks works very well so far. I just realized that my 10gbit is too slow for my RAID5. If I write directly to the RAID I get 2400MB/s read and 1200MB/s write (all flash). With CVM it is only 960MB/s read and 1000MB/s write. This has nothing to do with the previous problem and I hope t...

great, thank you very much, it has now worked.

One more question:
is it normal that the syn takes a long time (hours). is it actually just an empty file at the beginning?

Hello I have just installed 2 Hyper-V nodes. I have created and configured the CVM on each node according to the guide. Connection between them works and also host to CVM works. I have used the following script: param($addr="192.168.10.51", $port=3261, $user="root", $password=&qu...
