EMC VX-VS07-020 2TB NL-SAS Hard Drive Technology
NL-SAS drives have a SAS interface, but head, media, and rotational speed of traditional enterprise-class SATA drives, so they cost less than other SAS drives. This interconnect technology is capable of communicating at speeds of 6Gbps and is the technology of choice used in EMC storage systems. Increase your available storage with the EMC VX-VS07-020 2TB NL-SAS hard drive. When compared to SATA, NL-SAS drives have the following benefits:
- Dual ports allowing redundant paths
- Ability to connect a device to multiple computers
- Full SCSI command set
- No need for using Serial ATA Tunneling Protocol (STP), which makes it possible for SATA HDDs to be connected to a SAS HBA
- No need for SATA interposer cards, which are needed for pseudo–dual-port high availability of SATA HDDs
- Larger depth of command queues
EMC VX-DS07-020, 005049188, 005049750, 005049499, 2TB NL-SAS HDD Applications
EMC NL-SAS HDD with part numbers VX-VS07-020, 005049277, 005049748, 005049449 , is best suited for higher-capacity environments to help realize cost and capacity benefits. Sequential access applications have a tendency to maximize any caching advantages of the storage system, and take advantage of the higher density NL-SAS hard disk drives. In these applications, the speed at which the drive can transfer data from the platter has the greatest effect on overall performance. Thus, medium-to-large block and sequential I/O applications can reap the greatest benefits from the drive’s higher area-bit densities.
Some popular types of applications for the 005049188, 005049750, 005049499 / VX-DS07-020 EMC 2 TB 7,200 RPM NL-SAS drives are:
- Disk-to-disk backup
- Disk backup using traditional backup software. EMC arrays are tested and supported with most major backup applications.
- Improves backup and restore performance when compared to tape.
- Large application datasets
- Some applications, like seismic data interpretation, government intelligence, and life sciences research are immediately written out to tape due to their large size. When the tests need to be rerun, the data must be reloaded from tape, and then rerun. Now the information can stay online with EMC NL-SAS drives and businesses can improve their operational efficiency and time to market.
