while ExaGrid rolled out a system for larger midrange enterprises.

Sepaton brought out the S2100-DS3 family of disk backup systems designed to replace tape at remote sites and replicate data back to larger disk backup devices in the enterprise. The ExaGrid EX13000E is a network-attached storage box the vendor is aiming at larger customers that those who use its previous systems.

Sepaton protects remote, branch offices

Sepaton’s S2100-DS3 branch office systems work in a hub-and-spoke implementation with its enterprise S2100-ES2 system, which can scale up to 1.8 PB of capacity with deduplication. There are three DS3 configurations. All are 2U boxes with two six-core Westmere chips, 48 GB of memory and 4 Gbps Fibre Channel (FC) connectivity. The DS3 1000 has two FC ports, an ingest rate of up to 600 MBps and capacity ranging from 10 TB to 40 TB. The DS3 2000 has four FC ports, a 1.2 GBps ingest rate and capacity from 20 TB to 80 TB. The DS3 2000e has two FC and two 10 Gigabit Ethernet (GbE) ports for up to 1.5 GBps ingest rate and capacity from 20 TB to 80 TB .

The DS3 devices support VTL and Symantec OpenStorage (OST) interfaces concurrently. The starting price is $110,000 for the DS3 1000 with 10 TB. The base price includes Sepaton’s DeltaStor deduplication and DeltaRemote replication software.

Sepaton Vice President of Product Management Linda Mentzer said the DS3 platform supports many-to-one replication. She said the vendor has tested replicating 10 sites into one, but she is confident the systems can handle many more than 10 sites concurrently. Mentzer said she expects DS3 boxes to be used mostly by customers already running Sepaton in the data center, but some organizations might use them as standalone systems for smaller data centers.

“This is a more compact, self-contained platform [than the E2],” she said. “But it can be bidirectional. There are different types of deployments that can be utilized.”

Foxwoods Casino in Mashantucket, Conn, is among those utilizing a “different” type of deployment. Foxwoods principal engineer Michael Grillo said he is replicating data from his ES2 to DS3 remote sites for disaster recovery.

“They are marketing a hub-and-spoke model,” Grillo said. “We are using a spoke-and-hub model in which we are sending data from the central location to the office sites. We decided we needed to replicate all of our data, so the small units are a good financial fit and the physical footprint was small.”

ExaGrid bumps up capacity, speed

ExaGrid's EX13000E for multi-site backups, is a higher capacity, faster version of its previous high-end disk backup system, the EX10000E. The 3U EX13000E holds 32 TB of raw capacity, 26 TB usable, and can support a single backup of 13 TB. It has a backup throughput of 2.4 TB per hour. The 4U EX10000E, released in late 2009, has a backup throughput of 1.8 TB per hour. The EX10000E supports a single backup of 10 TB and holds 23 TB of raw data and 20 TB of usable capacity.

The EX13000E holds 16 2 TB SATA drives while the EX10000E holds 23 1 TB drives. The EX13000E has 16 GB of memory compared to 12 GB for the EX10000E. Both systems have six Ethernet ports, and up to two can be 10 GbE.

Like ExaGrid’s previous systems, the EX13000E uses a grid architecture to expand with additional nodes. The devices can be managed from a single UI and can replicate data between sites. The EX13000E can scale to 10 nodes. Pricing begins at $69,900.

“Part of what makes this interesting is ExaGrid is able to offer a 50-to-1 ratio in just a small network connection because it moves less data, which equates to costs,” said Dave Russell, Gartner’s vice president of storage and strategies. “ExaGrid still needs a media server, but it goes after I/O replacement. It will give you post-processing deduplication, replication, and backup from one appliance without the need for tape. You don’t have to physically transport tape.”
