As an enterprise systems user, you are most concerned about the security of your data and the reliability of the medium holding that data.Dell puts its Enterprise Hard Drive and Solid State Drive offerings through a rigorous validation process before they are ever considered as additions to our line of server and storage systems. Dell has stringent drive specifications for performance, duty cycles, Mean Time Between Failure (MTBF) and rotational vibration, which are all necessary for an Enterprise-level environment .These types of exacting specifications must be met before we will make them available for customer usage.Performance and Cost varies among the different HDD and SSD offerings. Please refer to the individual tabs below to assess the impacts in your applications.
Fast storage medium for random IO
Performance and availability for performance optimized applications
High capacity and exceptional $/GB for capacity optimized applications
Least expensive drives used in applications where low usage and limited total number of drives are applicable. Due to restrictions on use, these drives are available in a small number of systems and configurations.
In late April 2017, Dell has introduced a new 2.5” form factor 900GB 15K 512e 12Gbps SAS HDD with Enhanced Cache to boost Read performance in addition to the Advance Write Cache that comes standard in this family. TurboBoostTM (trademark of Seagate Inc) Enhanced Cache was Seagate’s major performance enhancement to standard enterprise performance HDD design (10K & 15K RPM rotational speed). This new 512e drive integrates small amount of eMLC NAND as cache, reducing latencies for significantly faster, predictable response times. Rather than constructing storage solutions with a mixture of discrete HDDs and SSDs, TurboBoost can often provide the best of both worlds. At the very least, TurboBoost can help to improve general work productivity through greatly improved availability of hot data (the data most frequently sought by the host) and greatly reduced IOPS response time.
Enhanced cache HDD benefits vary by applications - the greater the workload, the more effective they are. Ideal for building new high-performance servers, manage multiple transactions quickly, or drop-in replacements as the feature is active full time and doesnot require any enablement from host.
50/50 read/write workloads with highest endurance. This is generally recommended for running HPC, Database logging, and caching workloads.
70/30 read/write workloads with medium endurance. This is generally recommended for running e-mail/messaging, OLTP, and E-commerce workloads.
90/10 read/write workloads with lower endurance. This is generally recommended for running database warehousing, media streaming, and VOD workloads.
Lowest cost/small capacity SSDs designed to be used as a boot device in servers. Low endurance. Appropriate for all workloads.
Dell EMC enterprise SSDs support the following options:
SATA SSDs are based on the industry standard SATA interface. SATA SSDs provide reasonable performance for enterprise applications where performance is not paramount but minimizing cost is.
Developed by Toshiba Memory Corporation, value SAS is a new class of SAS SSD that leverages the PowerEdge SAS server infrastructure to deliver better performance, latency, and reliability than SATA SSDs, at a comparable price. These drives are lower cost and have lower performance than standard SAS SSDs, positioning their performance characteristics between SATA and standard SAS. Value SAS is an easy replacement for SATA SSDs and provide greater value for most enterprise applications.
SAS SSDs are based on the industry standard SAS interface. SAS SSDs combine superior reliability, data integrity, and data fail recovery making them better than both SATA SSD and Value SAS SSD for applications requiring the highest performance using SAS/SATA drives. Price is higher, but if performance is a strong requirement, then standard SAS SSDs is warranted.
The Dell EMC PowerEdge Express Flash PCIe SSD is a high performance solid state storage device that enables IOPS performance of up to 2000X more than conventional rotating hard drives.
