Everything except the hardware. The 150Vx gives you the same 500 GB of storage, support for around 100 mailboxes, full text search, legal hold, and audit trail as the physical 150. The difference is that it runs as a virtual machine on your own infrastructure instead of shipping as a rack appliance.

You'll need VMware, Hyper-V, or a supported cloud platform like AWS or vCloud Air to host it, plus the CPU, memory, and disk any standard VM needs. There's no proprietary hardware requirement. If your virtualization environment can run a standard VM, it can run the 150Vx.

Yes. The 150Vx is sold as a subscription license rather than a one-time appliance purchase, billed monthly or annually. That's a lighter upfront cost than buying hardware, though it means ongoing payments instead of owning the box outright.

Either. The 150Vx can mirror everything to the Barracuda Cloud for backup and longer-term retention, or you can manage the storage yourself within your own virtual environment. It's your call based on how much you want Barracuda handling versus your own infrastructure.

Yes. The 150Vx archives from the same platforms as the physical 150, including Exchange, Office 365, Google Workspace, GroupWise, and Lotus Notes, so switching to virtual doesn't limit which mail systems you can connect.
