Yesterday VMware released the latest SRM product, version 8.2. This release introduces an SRM virtual appliance that runs the Photon OS and within the OS containers for SRM itself and any supported SRAs. This release still offers a Windows-based solution, but VMware will eventually fully transition to the appliance. You can check out the release notes here.
Unfortunately, currently no version of the VMAX/PowerMax SRDF SRA supports SRM 8.2, either the appliance or the Windows version. We are targeting early next year.
