Samsung Introduces AutoCache V3.0 Software That Supports VMware vSphere APIs for IO Filtering

Samsung Electronics, Co. Ltd., the world leader in advanced memory technology, today announced at VMworld 2015 US, its first enterprise-class caching software solution – the Samsung AutoCache v3.0. As part of Samsung’s partnership with VMware, the caching software is scheduled to be one of the first caching solutions used with the new VMware vSphere APIs for IO Filtering, fully supporting write-back caching in virtualized environments.

AutoCache v3.0 relieves I/O bottlenecks associated with disk drives used in data centers by transparently moving copies of frequently accessed data to Solid State Disks (SSDs), where it may be accessed quicker. AutoCache implements write-back caching, where data is first written to SSDs and then copied to disk drives. This enables the system to handle bursts of high-write requests at SSD speeds instead of disk speeds. The technology supports all types of SSDs including Non-Volatile Memory Express (NVMe), Serial Advanced Technology Attachment (SATA) or Serial Attached SCSI (SAS) SSDs.

“AutoCache v3.0 provides a highly efficient way for IT managers to double, or even triple, the effective number of Virtual Machines supported per server,” said Thomas Bolt, vice president of software development, Samsung Semiconductor, Inc. “By improving server caching capabilities we are delivering superior storage performance for all enterprise SSDs, by simply moving the task of accessing stored data in virtual machines to the solid state drive itself.”

By removing the traditional I/O bottlenecks in virtual environments associated with multiple Virtual Machines (VMs) accessing the storage resources, Samsung’s AutoCache v3.0 enables a disk I/O performance increase in each VM of up to 400 percent or more. AutoCache v3.0 can be used to accelerate a variety of workloads and databases including Online Transaction Processing (OLTP), real-time big data analytics, data warehousing, business intelligence applications, Virtual Desktop Infrastructure (VDI), public and private cloud environments and general virtualized workloads.

Providing vertical integration from storage device to host, AutoCache v3.0 streamlines the work of VMs servers, while reducing overall storage and caching costs in virtualized data centers. The technology is thoroughly transparent, enabling a smooth integration, without disrupting data center operations.

Optimized for use with Samsung SSDs, AutoCache v3.0 features DRAM (Dynamic Random-Access Memory) caching, permitting caching to DRAM and solid state storage within the same server. In addition, a SSD clustering feature provides a caching device at each node, each of which will support a maximum of eight SSDs in a single server.

The new Samsung software provides adaptive caching, whereby the AutoCache software analyzes I/O patterns to determine which I/Os will benefit from caching and automatically cache only those.

It also features role-based administration, which permits IT managers to set individual access and permission policies to their IT staff.
