VTL solutions "trick" the backup server into thinking it is still backing up to tape, though the target is now SATA
disk. VTLs generally slip into the existing backup environment unnoticed and work with traditional backup applications to expedite the backup and restore process.
StorageTek's D-series
disk systems give customers high-performance Fibre Channel storage solutions that support Information Lifecycle Management(TM) initiatives and maximize IT budgets.
Some accounting applications using optical
disk technology include the following:

Disk Monitor Lite lets virtual server admins monitor individual VMs for virtual machine
disk (VMDK) file size, average
disk reads/writes, and data store.
Most material drawn toward a black hole doesn't dive directly in but forms a swirling
disk, called an accretion
disk, around the hole.
A copy of this changed data is moved to a central site to be stored on
disk. Some technologies can minimize the size of data transfer by discerning and moving just the byte-level file modifications.
The
disk surrounds a star called HD 142527, which lies 650 light-years from Earth.
Here's the thing to know about
disk lasers: "Improved beam quality at higher power--approaching C[O.sub.2] beam qualities," says Morris.
Built-in hard
disk drive and over seven hours*1 of DVD-quality video recording
With its 2.0 release, Pathlight VX becomes the first open system backup product to combine the capacity and characteristics of
disk and tape in a single, unified system, using advanced policy-based data management technology to provide total system capacities of nearly 3,000 terabytes.
These include silicon based dynamic and static random access memory (RAM), magnetic hard
disk drives, optical
disks (including write once read many [WORM], magneto/optic, CD-ROM, and DVD
disk, and magnetic tape.
NIST has successfully developed an experimental technique and a numerical model to study the dynamic behavior of a head colliding with a
disk. In the theoretical part of the study, a three-dimensional finite-element model was constructed to represent the overcoat, media and substrate, as well as a two-mass system, to represent the air-bearing slider.
