Avamar Data Store

Symmetrix: Classified as Enterprise level storage, mostly used for business critical tier 1 Applications. Supports mainframe environments, open systems and many other legacy host environments. Major competitors to the Symmetrix are HDS and HP XP’s. IBM ESS (Shark’s) at one time were considered a close match, but with the new technology and latest EMC acquisitions, EMC has taken the Symmetrix products to a new level.

DMX: An extension of Symmetrix. This platform is classified as Symmetrix DMX (Direct Matrix Architecture). EMC is one of the pioneers to bring Solid State Disk to the DMX4 Environments.

Clariion: Classfied as Tier 2 Storage. Used mostly with mid size businesses as backend storage or as backup devices at larger enterprises.

Disk Library (DL): Using a Falconstor front end and a Clariion Back End, EMC has designed a virtual tape library solution, that emulates tape devices and stores the data on disk drives (backups run at disk speed).

Connectrix: Using Brocade, Mcdata and Cisco switches, EMC has taken the Connectrix platform one level ahead integrating it with its SAN, NAS and CAS Environments.

Celerra: NAS (Network Attached Storage), mostly known as IP Storage. Used for backup applications, integrates NAS and ISCSI technologies.

Centera: CAS (Content Address Storage), used mostly in financial, utilities and medical fields to follow the Sarbanes Oxley and HIPAA Compliance and Governance Requirements.

Avamar Data Store: Avamar Platform is primarily used with backup, recovery, data deduplication. A product still in its infancy with a lot more integration required.

RSA Products

Various Implementations of RAID Types with EMC Symmetrix / DMX and Clariion Technology.

RAID (Redundant Array of Inexpensive or Independent Disk)

RAID 0 – Striped Disk Array without Fault Tolerance: Provides data striping (spreading out blocks of each file across multiple disk drives) but no redundancy. This improves performance but does not deliver fault tolerance. If one drive fails then all data in the array is lost.

RAID 1 – Mirroring and Duplexing: Provides disk mirroring. Level 1 provides twice the read transaction rate of single disks and the same write transaction rate as single disks.

RAID 5 – Block Interleaved Distributed Parity: Provides data striping at the byte level and also stripe error correction information. This results in excellent performance and good fault tolerance. Level 5 is one of the most popular implementations of RAID.

Now Available 3 RAID 5 and 7 RAID 5 with EMC DMX Platform.

RAID 6 – Independent Data Disks with Double Parity: Provides block level striping with parity data distributed across all disks.

RAID 0 + 1 – A Mirror of Stripes: Not one of the original RAID levels, two RAID 0 stripes are created, and a RAID 1 mirror is created over them. Used for both replicating and sharing data among disks.

RAID S (3 + 1): EMC Symmetrix / DMX disk arrays use an alternate, proprietary method for parity RAID that they call RAID-S. Three Data Drives (X) along with One Parity device. RAID-S is proprietary to EMC but seems to be similar to RAID-5 with some performance enhancements as well as the enhancements that come from having a high-speed disk cache on the disk array.

RAID S (7+1): EMC DMX disk arrays use an alternate, proprietary method for parity RAID that they call RAID-S. Seven Data Drives (X) along with One Parity device. RAID-S is proprietary to EMC but seems to be similar to RAID-5 with some performance enhancements as well as the enhancements that come from having a high-speed disk cache on the disk array.
