Write speed on MD3820i ISCSI 10G
Hi Everybody
I got an MD3820i PowerVault with 11 SSD PM1633a. 2 R440 Esxi 6.5 are accessing it by ISCSI (2 differents VLAN) connection through 2 N4032 stacked switches. Servers, San switches and MD are connected in 10G.
Dell Install services says my setup is compliant with there requirements and Dell support checks log : All hardware is OK.
I tried some disk benchmarks on a VM with crystalmarkdisk to check the read and write perfs. I obtain 1700MB/s read and only 700MB/s write. With 11 SSD that can do 900MB/S each, i dont understand why i can't get 1700MB/s write too.
If someone has an idea, it would be great
Best regards
