Get more application performance from your DAS

PowerEdge server (R730xd shown) with SanDisk DAS Cache software

Deploy one PowerEdge server with SanDisk DAS Cache software, HDDs, and at least two SSDs


SanDisk DAS Cache

Reach greater performance

Do more in less time using accelerated data analytics, which provide increased performance for high-IOPS Linux®, VMware® and Microsoft® Windows Server® applications, while realizing a lower cost per user, greater transactions per second (TPS), with a reduced average response time (ART).

Deploy with flexibility

Select from a variety of connected media as cache devices, storage controllers and operating systems. With options to deploy on select 13th generation, FX2 and R920 Dell EMC PowerEdge™ servers, a wide assortment of density and drive options are available.

Maximize resource utilization

Leverage SSDs to meet your needs: combine SSD resources across the entire server-storage infrastructure, use a single SSD cache group to accelerate multiple local storage groups or volumes, or expand local cache with hot-plug drives as new cache for new server devices.

SanDisk Cache DAS

SanDisk DAS Cache can surge OLTP on Microsoft SQL Server database transactions up to 11x more on a Dell PowerEdge R730xd server.

Results based on independent testing by SanDisk using the TPC-C benchmark test on Microsoft SQL Server versus a baseline configuration with HDD-based storage and published in a September 2014 whitepaper,SanDisk® DAS Cache: OLTP Performance.” Actual performance will vary based on configuration, usage and manufacturing variability.

Get up to 75% reduction in average response time for online transactions and consolidate up to six IBM 3650M3s to one Dell PowerEdge R730xd with SanDisk DAS Cache.

Based on Principled Technologies report "Consolidating older database servers with the Intel processor powered Dell PowerEdge R730xd using SanDisk DAS Cache," September 2014, commissioned by Dell. Actual performance will vary based on configuration, usage and manufacturing variability. For more information, please visit:
