Qsan Firmware Updated Solution for VMware 7.0 U2 Compatibility

Qsan Technology Inc. has released new firmware as solution to the VMware 7.0 U2 compatibility issue in storage updated as #2113956 in VMware, Inc. Knowledge Base.

KB #2113956 mentioned that an ESXi host loses connectivity to a VMFS datastore with VAAI ATS.

The recommended resolution from VMware is to disable VAAI ATS heartbeat on all hosts sharing the datastore where these errors are seen.

The company had conducted thorough testing in the lab and concluded that such issue would lead to data inconsistency which may corrupt data before users are aware of this compatibility issue. The proactive approach from the company is to provide solution from storage side so customer could upgrade the firmware in storage side before upgrading to VMware 7.0 U2. It will prevent this issue while still maintaining existing environment and all VMware advanced features without interruption.

XCubeFAS Xf3126d

The solution is added to the firmware v2.0.1a (and later) for XCubeSAN and XCubeFAS. The company recommends users to upgrade the firm’s storage systems with these latest firmware before upgrading to VMware 7.0 U2.

The firmware is available in the firm’s website or users can contact Qsan support if more assistance is required.
