SCV2020 Round Robin
Hello,
On a recently installed Dell SCV2020 (last firmware) with 3 nodes in SAS direct attached mode, each LUN in VMWARE ESXi 6.0U2 with Round Robin path selection, I have ACTIVE/STAND BY paths....
In each R630 Servers I have 1 HBA 2ports DELL 12GB SAS
Does SCV2020 support ACTIVE/ACTIVE in this configuration ?
Thanks for your help

In SAS virtual port mode , a volume is active on only one storage controller , but is visible to both storage controllers. ALUA controls the path that a server uses to access a volume. If a storage controller becomes unavailable, the volume bacomes active on the other storage controller. The state of the paths on the available controller are set to Active/Optimized and the state of the paths on the other storage controller are set to Standby. (Dell Storage Center SCv2000 and SCv2020 Storage System Deployment Guide, page 58; 2015-7 rev.A01)
