VirtuCache is kernel mode software for VMware that automatically caches recently and frequently used data (reads and writes) from and to any storage appliance to any in-host SSD. By doing so we improve the performance of your SAN based storage appliance, without requiring you to upgrade or replace any of your existing storage gear.
VirtuStor is software installed on any commodity physical servers. It then clusters these servers together and presents it as a traditional iSCSI appliance.You can mix and match servers, hard drives, and SSDs of any make, model, and antiquity. You can scale up storage by hot adding servers and drives.
