SanDisk DAS Cache Compatibility Matrix
SanDisk DAS Cache overview
SanDisk DAS Cache is a software application driver installed on a system primarily to accelerate the speed of storage input/output (I/O) operations, which in turn improves the performance of I/O intensive applications.
SanDisk DAS Cache software is compatible
with:
- Linux—SanDisk DAS Cache software for Linux, version 1.5, is a kernel module that runs within the Linux operating system.
- VMware vSphere—SanDisk DAS Cache software for VMware vSphere, version 1.5, is a software module that runs within VMware ESXi 5.5.
- Windows—SanDisk DAS Cache for Windows, version 1.5, is a software application driver that accelerates the speed of storage.
SanDisk DAS Cache software accelerates server applications by leveraging a Solid‐State Drive (SSD) installed on the host server and used specifically as a read‐write cache for hot data—the data that applications access most frequently. In most cases, less than 20% or even 10% of active data is actually hot data. Although hot data constitutes a small fraction of the total data in storage, read and write operations on this data typically account for at least 70% to 80% of server I/O. This is why a relatively small SSD‐based cache for hot data can provide I/O performance close to what you can achieve if you store all of an application's data on an SSD device.
- NOTE: In this document, the term SSD device refers to any directly attached NVMe PCIe, AHCI PCIe, SAS, or SATA physical block device used as a cache. A physical SSD device might be an entire device, or a partition on a device, attached internally or externally. In any form, a cache device is referred to as an SSD in this document.
