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]
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 ...
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 Symmetrix system was an EMC's enterprise storage array.It combined dozens of hard drives into a single virtual device that was then directly attached to a computer or I/O channel, or shared on a storage area network or a local area network.
Flash memory devices impose no seek latency. Wear leveling: flash memory devices tend to wear out when a single block is repeatedly overwritten; flash file systems are designed to spread out writes evenly. Log-structured file systems have all the desirable properties for a flash file system. [1] Such file systems include JFFS2 and YAFFS.
The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an ...
The form factor is a half-width 1U or 2U device known as an X-blade, two of which are mounted side by side in the storage processor enclosure. This provides a fully redundant active-active configuration, with both storage processors serving requests and each acting as failover for the other so that initiators see the array as active-passive.
