The Dell EMC Unity product line includes the hybrid (flash + HDD) 300/400/500/600 models, the all-flash 300F/400F/500F/600F models, and the Dell EMC Unity VSA virtual appliance deployable on vSphere. The basic enclosure for the hybrid and all-flash models is a 2U box with 25-2.5-inch drive slit expansion trays, called a Disk Processor Enclosure ...
Dell EMC XtremIO is Dell EMC's high-volume, high-capacity all-flash enterprise storage platform. [1] The current version is the X2 line. The XtremIO X2 storage platform is primarily designed for applications that benefit from its data reduction and copy data management capabilities. It also targets organizations with large VDI deployments. [2]
Dell EMC Isilon is a scale out network-attached storage platform offered by Dell EMC for high-volume storage, backup and archiving of unstructured data. [1] It provides a cluster-based storage array based on industry standard hardware, and is scalable to 50 petabytes in a single filesystem using its FreeBSD -derived OneFS file system .
The new architecture could support “hundreds of thousands of terabytes of storage and millions of IOPS (input/output per second) supporting hundreds of thousands of VMware and other virtual machines in a single federated storage infrastructure.” [7] VMAX (then called EMC Symmetrix V-Max) was the first storage system to support this new ...
NetApp FAS3240-R5. Modern NetApp FAS, AFF or ASA system consist of customized computers with Intel processors using PCI.Each FAS, AFF or ASA system has non-volatile random access memory, called NVRAM, in the form of a proprietary PCI NVRAM adapter or NVDIMM-based memory, to log all writes for performance and to play the data log forward in the event of an unplanned shutdown.
Hybrid storage arrays aim to mitigate the ever increasing price-performance gap between HDDs and DRAM by adding a non-volatile flash level to the memory hierarchy. [1] Hybrid arrays thus aim to lower the cost per I/O, compared to using only SSDs for storage.
Windows Vista allows only one device to be used, while Windows 7 allows multiple caches, one per device, up to a total of 256 GB. [5] ReadyBoost compresses and encrypts all data that is placed on the flash device with AES-128; Microsoft has stated that a 2:1 compression ratio is typical, so a 4 GB cache would usually contain 8 GB of data.

Compellent’s storage area network (SAN) system, called "Storage Center", combines several virtualized storage-management applications with hardware. The product tracks metadata, information about each block of data stored on the Compellent system, including the date and time written, frequency of access, associated volume, type of disk drive used, type of data stored and RAID level.
