Faster data dedupe for the midrange
The DD670 is the first Data Domain system based on the Intel Xeon 5500 Nehalem processor. EMC claims the DD670 performs at 5.4 TB per hour of aggregate inline deduplication throughput with the DD Boost software introduced in May, and 3.6 TB per hour with NAS or virtual tape library connectivity. The system supports up to 76 TB of raw capacity (56 TB usable), and replication from 90 remote sites with smaller Data Domain devices.
Shane Jackson, director of product marketing for EMC's Backup and Recovery Systems Division, said the Nehalem processor gives the DD670 a significant speed advantage over midrange competitors such as the Hewlett-Packard (HP) Co. StorageWorks D2D4312, ExaGrid Systems EX10000E, and Quantum Corp. DXi6530-50 and DXi6520.
Pricing for the DD670 begins at $110,000.
Data deduplication for mainframe virtual tape library
The Deduplication Storage Expansion for the EMC Disk Library for Mainframe (DLm) uses the DD880 enterprise data dedupe system along with EMC's DLm960.
The DLm960 performs IBM tape emulation and uses EMC's Celerra NS-960 storage systems. The DLm960 with deduplication scales from two to six virtual tape engines (VTEs) and up to 12 FICON connections for a front-end ingest performance of more than 4.3 TB per hour. EMC claims the DD880's deduplication could add as much as a petabyte (PB) of logical storage in a single cabinet, bringing the DLm960's logical capacity to nearly 3.5 PB. Data dedupe also makes the DLm960's bi-directional replication between two systems more effective.
"This gives mainframe users a way to get dedupe into their backup and archive workloads," Jackson said.
Silverton Consulting president Ray Lucchesi said the mainframe market is key to EMC because many of its enterprise storage systems are connected to mainframes.
"With Symmetrix, EMC is already supporting that space," he said. "So deduplication can help them there."
In February, IBM added dedupe capabilities to its System z mainframe with the IBM System Storage TS7680 ProtecTIER Deduplication Gateway for System z.
Before it was acquired by EMC last year, Data Domain had a partnership with mainframe virtual tape library vendor Luminex to add data dedupe for mainframe systems.
DL VTLs expand without data dedupe
The DL5000 VTL series is also based on the Nehalem processor. The single-engine DL5100 uses the EMC Clariion CX4-240 for storage and the dual-engine DL5200 uses Clariion CX4-960. The DL5000, which replaces the DL4000, scales from 8 TB to 1.4 PB of usable storage and 2.8 PB of logical capacity assuming an average compression ratio of 2:1. Like the DL4000, the DL5000 does not include deduplication.
Also like the DL4000, the DL5000 runs rebranded FalconStor software for core VTL functions. EMC also sold Quantum deduplication software for the DL4000 before acquiring Data Domain last year, but now positions the DL5000 for customers who want VTL without deduplication.
"VTLs provide temporary storage on a big disk before sending off to tape, so they can still be effective without deduplication," Lucchesi said.
Pricing starts at $390,000 for the DL5200 and $204,000 for the Dl5100.
