deployment of DL2000.
PowerVault DL2000 — Powered by CommVault additionally comes with deduplication capability
built into the software, combining two components of IDM in a single product. Archive
functionality can also be added to create a single solution that will protect and archive data while
optimizing disk usage.
Tiered storage
Implementing tiered storage arrays can deliver important cost savings over a "one-size-fits-all"
model of storage. Tiering storage allows customers to use their high-performance arrays to host
the primary data. For secondary data, which is not accessed as often, the organization can use
comparatively inexpensive storage arrays.
Dell's portfolio of storage products includes Fibre Channel (Dell/EMC CX Arrays) and iSCSI
arrays (EqualLogic PS Series and the PowerVault MD series) and direct-attached storage and
tape — a broad range of offerings to enable tiered storage. Our consulting services help
organizations classify their data and optimize the way it's stored, protected, and managed in a
tiered architecture.
The Dell/EMC CX4 and the EqualLogic PS5000X are ideal for hosting primary data for high-
performance applications such as e-mail and databases. For secondary storage, we
recommend the Dell/ EMC CX4 array with SATA drives or the EqualLogic PS PS5500 with
mirroring to disaster recovery sites or software for disk-based backups.
Deduplication solutions
Deduplication is a storage-optimization technology that reduces the data footprint by deleting
multiple copies of redundant data and storing only unique data. Copies of the data are replaced
by references to the original data. Deduplication of redundant data at the file, sub-file, or block
level can help make disk-based backup as economical as tape backups.
Dell has announced a new set of data deduplication products for early 2009. These products will
use the same technology across the company’s PowerVault, EqualLogic, and Dell/EMC
families, thereby delivering compatibility for organizations that want to be able to replicate and
deduplicate between multiple locations. The new deduplication products are designed for
enterprise customers who need more advanced, higher capacity deduplication solutions.
Consulting services
Dell has introduced services that help in analyzing customers’ environments and developing
action plans designed to improve data recovery capabilities. Dell can help identify flaws in
existing data protection processes and design, update backup, restore as well as set up a
disaster recovery infrastructure to meet your organizational data protection requirements. Dell
uses a tools-based approach to assess customers’ backup environments so that design is
based on actuals as well as Dell field expertise and point-of-proof knowledge base. These
