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.
SAS (Serial Attached SCSI) is the interface architecture used to transmit data from the storage controllers to the disk drives in the Adaptable Modular Storage 2000 family. The SAS interface is a full duplex, point-to-point architecture with up to 9600 MB/sec of total system bandwidth and up to 32 links available for concurrent I/O activity.
Multiple different storage resources can reside in the same storage pool, and multiple storage pools can be configured within the same DPE/DAE array. Each storage pool is tiered based on the performance characteristics of the storage technology used, with SSD-based storage at the top “extreme performance tier,” serial-attached SCSI (SAS) in ...
Storage servers housing 24 SAS hard disk drives per server. A typical Serial Attached SCSI system consists of the following basic components: An initiator: a device that originates device-service and task-management requests for processing by a target device and receives responses for the same requests from other target devices.
The IBM® TS2900 Tape Autoloader is an entry-level automated backup for rack systems and small to midsize businesses. With a low-profile, high-density storage capacity, the TS2900 is ideally suited for backup and archival operations. The TS2900 is available with half-height LTO Ultrium tape technology, with 6 Gbps SAS drive options.
Most current VTL solutions use SAS or SATA disk arrays as the primary storage component due to their relatively low cost. The use of array enclosures increases the scalability of the solution by allowing the addition of more disk drives and enclosures to increase the storage capacity.
PowerVault is a line of data storage and backup products formerly from Dell, and currently for Dell EMC. After Dell acquired EqualLogic for its iSCSI products in 2008, and Compellent Technologies in 2011, the PowerVault line was positioned as less expensive than the other product lines.
A disk array controller provides front-end interfaces and back-end interfaces. The back-end interface communicates with the controlled disks. Hence, its protocol is usually ATA (a.k.a. PATA), SATA, SCSI, FC or SAS. The front-end interface communicates with a computer's host adapter (HBA, Host Bus Adapter) and uses:
