VMware shops are targeted by the Proximal AutoCache software, which utilizes a unique feature that allows a single installation within the hypervisor, rather than deploying drivers in every guest operating system instance. This reduces the amount of system management effort and eases operations such as vMotion. Implementing a write-through read cache by keeping a copy of hot data on a PCIe or direct-attached SSD, Proximal joins other cache software players EMC, FlashSoft (acquired by SanDisk), IOTurbine (acquired by Fusion-io), SanRad (acquired by OCZ), STEC, and independents Nevex (who partners with Texas Memory), and Velobit.
While Proximal's initial release of AutoCache supports VMware ESXi 4.1 and 5.0 hypervisors, it integrates management functions through vSphere and vCenter. Proximal AutoCache is available immediately from its channel partners at a starting price of $999 for up to 500GB of cache capacity.

Texas Memory’s addition of a direct boot capability is a first for a pure-play PCIe interfaced SSD. Unlike other bootable PCIe cards that use a SATA- or SAS-to-PCIe bridge, the Texas Memory device uses the full speed available from the PCIe interface during the boot process. This reduces the cost of server hardware that accesses shared storage by eliminating the expense of adding a RAID interface and hard drive.
Rapid boot time for servers is extremely important because an IT administrator usually attends the boot. PCIe boot time can be reduced to a matter of a few seconds compared to five or more minutes from a rotating drive. The boot feature is available immediately, and existing RamSan-70 and -80 customers can obtain the boot feature via a download from Texas Memory’s customer support team.
