While there are a number of software caching solutions each has potentially significant weaknesses. They are either owned by a hardware vendor, which can limit choice or they don’t fully support the hypervisor or guest OS that the customer is most concerned about. As we learned in this video briefing Proximal Data CEO Rory Bolt they may be set to solve these problems.
Proximal Data delivers a server side, software-based caching solution that can work with a variety of solid state flash hardware solutions including PCIe controllers and SSDs. Proximal Data’s AutoCache solution works at the hypervisor level, meaning that it does not require a driver in the guest OS. Because it runs at the hypervisor level it coordinates its actions with the hypervisor. AutoCache supports vMotion, Distributed Resource Manager (DRS), VMware High Availability (HA) and vStorage API for Array Integration (VAAI). This means that cached data is fully in sync with the virtual environment so that data integrity is maintained.
