ExaGrid offers an easy to use disk-based backup solution with 20 to 1 data de-duplication at 30% the cost of SATA storage.
ExaGrid's Byte-level Data De-duplication technology stores changes from backup to backup instead of storing full file copies. This unique approach reduces the disk space required by at least 20 to 1, delivering unparalleled cost savings and performance at 30% the cost of standard SATA storage. |
ExaGrid EX Series Product LineExaGrid offers a highly scalable disk backup with deduplication solution that works with your existing backup application and combines high quality SATA storage, compression and byte-level data deduplication with a virtualized GRID architecture. This unique approach reduces the disk space required for backup by a range of 10 to 50:1, delivers best-in-class scalability and unparalleled cost savings.
Scalable GRID ArchitectureThere are six core ExaGrid disk-based backup servers. These servers include GRID computing software. When plugged into a switch they virtualize into one another. As a result, any of the six configurations can be mixed and matched into a single GRID system, with full backup capacities up to 100TB, in granular increments. Once virtualized, they appear as a single system to the backup server. Load balancing of all data across servers is automatic and multiple GRID systems can be combined for additional capacity. ExaGrid's unique approach to scalability provides the following benefits:
Post Process Data DeduplicationExaGrid's innovative approach minimizes the amount of data to be stored by providing standard data compression for the most recent backups, along with byte-level data deduplication for all previous backups. ExaGrid's post-process deduplication technology stores changes from backup to backup instead of storing full file copies. This unique approach reduces the disk space required by at least 10, and up to 50 to 1, delivering unparalleled performance for the fastest backups and restores, all in a solution that costs the same as a new tape library. Six Core ExaGrid Server Configurations
For example, a 5TB ExaGrid server can store a 5TB full backup (5TB of primary data) plus up to 16 weeks of retention/history, while a 2TB server can take in a 2TB full backup (2TB of primary data) plus up to 16 weeks of retention. If a 100TB system is required, then ten EX10000Es are plugged into the switch and virtualize into a single system. Six Mix and Match Servers
Examples of several common ExaGrid system GRID configurations between 7 TB and 100 TB
On-site and Off-site, or Multi-site Disk-based BackupIn addition to single site, ExaGrid supports multi-site topologies. Each site can act as a data backup target for storage of local backups. Further, each site can transfer just the changed bytes to an off-site location so that the off-site location can perform data recovery if the local site is lost. This support is bi-directional allowing systems used as off-site repositories to also act as local targets for data backups at those sites. With two-site configurations, it is very common to have both systems act as a local data backup target and to cross-protect each other by replicating the local data to the opposing site. With multi-site topologies, a centrally located site may cross protect with one of the other locations for long-term retention and disaster recovery for the central site backup data.
Multi-site Topology
Core Server ComponentsExaGrid servers are comprised of the following:
Each server includes the appropriate amount of processor, memory, disk and GigE for the amount of data. As each server is plugged into the switch and virtualized into the GRID it brings not only disk capacity but also processor, memory and GigE such that performance is maintained as data is added.
