Deduplication Reviews – Exagrid vs. EMC vs. Quantum vs.HP

Excerpt….

Technology analyst Gartner estimates place the deduplication appliance market at $1.74 billion in revenue last year. That’s a growth rate of 18% over the previous year.

“While EMC continues to claim the lion’s share of the market, late-comer HP is making good progress, and Fujitsu reported some large-scale adoption in Europe and Japan,” said Rinnen. “Quantum remains a solid contender, whereas Dell is ramping up its DR series appliances for SMBs. ExaGrid and Sepaton are positioned as Visionary vendors due to their innovative architectures.”

ExaGrid

Exagrid believes that deduplicating backups during the backup process (inline) it too compute-intensive, resulting in a longer backup window. To overcome this, ExaGrid uses a landing zone where backups can land straight to disk without inline processing, resulting in fast backups and a short backup window. Deduplication and offsite replication occur in parallel with backups so they never impede the backup process, as they are second order priority.

….

ExaGrid offers a total of nine appliance models, which can be mixed and matched into a single grid. This can scale from a 1 TB full backup up to a 294 TB full backup in one grid. It also allows for replication to a second site for disaster recovery as well as enabling multiple data centers to cross protect between each other. The list price for the ExaGrid EX7000 appliance is $29,000, whereas the EX13000E is $42,000, and the EX21000E is $59,000.

Gartner saw ExaGrid as being successful in the midmarket and in small enterprises, and thought its grid architecture offered pay-as-you-grow benefits, as well as having deeper integration with Veeam than many competitors. But the analyst firm saw limitations in its reach beyond North America, as well as limited cloud support.

Quantum

The Quantum DXi Series utilized the StorNext 5 file system to accelerate storage workflows and simplify data protection. The company recently streamlined its disk backup/deduplication portfolio based on three platforms – the DXi6900 for midrange to enterprise environments, the DXi4700 for SMB to midrange implementations, and the DXi V-Series for virtual environments. The DXi6900 with 17 TB usable capacity has an $88,000 list price, the DXi4701 with 5 TB is $16,000 and a free DXi V1000 virtual deduplication appliance is available to store up to 15 TB of deduplicated data.

….

As such, Quantum provides self-encrypting 4 TB drives in DXi Series models using AES 256-bit government grade encryption that is performed by the drives without performance impact. A recent development is capacity-on-demand licensing. For example, this enables users to scale a DXi6900 from 17 TB to 510 TB without any licensing complexity. From one Quantum appliance, users can replicate to Quantum’s Q-Cloud Protect data center as a means of offsite protection. If the data is deduplicated, Burns characterizes the cost at pennies per GB per month.

Gartner called attention to Quantum’s strong tape heritage, which gives it strong tape integration capabilities compared with its competitors. The analyst firm also commented favorably on its licensing model, which gave users better flexibility and affordability. On the downside, the DXi’s Accent deduplication distribution software only supports Symantec NetBackup and Backup Exec, and Quantum offers online support for application-native backup tools such as Oracle RMAN.

HP

HP supplies several deduplication appliances. The 4 TB StoreOnce Virtual Storage Appliance (VSA) which includes StoreOnce Catalyst (pricing starts at $1,500). The StoreOnce Backup 2700 (dedicated hardware appliance) offers 5.5 TB of usable storage prior to deduplication (approx. 110 TB of backup data assuming a 20:1 deduplication ratio) and is priced starting from $12,500.

Other products are available offering different capacity and performance points through to HP’s flagship StoreOnce 6500. It offers the highest availability with failover and autonomic restart for those who want to ensure their backups don’t fail. This product scales to 1728 TB of usable space prior to deduplication and restore speeds up to 75 TB/hr. Prices start at $375,000.

“Consider a holistic approach to data protection,” said Andrew Dickerson, senior marketing manager, backup, recovery and archiving solutions, HP Storage. “It may be that your organization can move some of its primary data to a different type of storage enabling the business to use that data for intelligence purposes, to help move the business forward while at the same time backing up less data each day, to a deduplicating appliance.”

Gartner felt that StoreOnce had good integration capabilities with backup applications such as HP Data Protector and Symantec OpenStorage Technology (OST)-based applications, but saw some weakness in entry-level and midrange models.

EMC

No pricing available.

Gartner noted that EMC has achieved commercial success with Data Domain deduplication backup appliances, which offer a variety of configurations, deduplication capabilities and ingest speeds. The analyst firm called it the “broadest ecosystem of backup and enterprise application support, including deeper integration with EMC’s Avamar and NetWorker via Data Domain Boost.”

But Gartner also noted some customer gripes around pricing, and the lack of a scale-out architecture for easy upgrades and migration.

Quantum Releases “Big Data” M6600 Appliance

The StorNext M660 Metadata Appliance starts at $120,000; StorNext M330 starts at $75,000. Both appliances are available now.

StorNext M6600 Metadata Appliance stores up to 800 million files.

Quantum on Tuesday announced the StorNext M660, a new larger version of its metadata appliance. The device aims to store large numbers of objects generated from video editing, genomics, remote sensing, video surveillance, and seismic exploration applications.

Twice as large as the company’s M330 appliance, the StorNext M660 can store up to 800 million files in as many as eight file systems. The StorNext M660 can be integrated with Quantum Q-Series Storage for high-performance primary data as well as with the StorNext AEL Archive for near-line archiving.
