Promise ships iSCSI-to-SATA RAID
Promise Technology last month claimed to be first to market with a RAID array that has hardware-accelerated iSCSI connectivity and support for 3Gbps Serial ATA (SATA) II disk drives. The VTrak M-Class subsystems are available in six configurations, with 8, 12, or 15 drive bays, up to 7.5TB, 2U and 3U form factors, and dual host connections (either iSCSI or Fibre Channel). In addition to 3Gbps speed, the arrays have other SATA II features such as native command queuing (NCQ), staggered spin-up, and hot-swappable drive support.
iSCSI hardware acceleration is enabled via TCP/IP offload engine (TOE) chips from QLogic.
The VTrak M-Class arrays include a Predictive Data Migration feature that proactively detects potential drive failures and migrates data to a healthy drive. Another key feature in light of the array’s support for SATA is a reduction in drive rebuild times. Promise officials claim that a 1TB rebuild takes only three to seven hours, compared to more than 30 hours for some other SATA subsystems.
Pricing starts at $4,199 for an eight-bay configuration, not including drives. The RAID arrays support virtually all RAID levels, with an implementation of RAID 6 due next month. (RAID 6 protects against simultaneous drive failures.) www.promise.com.
Infortrend intros Ultra320 RAID
Infortrend recently began shipments of RAID arrays with Ultra320 (320MBps) SCSI host and drive interfaces. The EonStor U12U-G4020 and U16U-G4020 are based on the company’s ASIC266 chip with an XOR engine. In a RAID 5 configuration, Infortrend claims sequential read rates of up to 512MBps and sequential write rates up to 326MBps. The subsystems include two host ports and two drive channels. www.infortrend.com.
JMR packs 42 SATA drives in 4U
JMR Electronics’ ORCA is a SATA-based disk subsystem that can be configured with up to 42 disk drives, or 16.8TB, in a 4U form factor. The system includes three fans and power supplies and triple-active Multi-Parity RAID controllers. In addition to SATA, the controllers support Fibre Channel drives. The architecture includes Disk Controller Modules (DCMs) in a cluster configuration with fail-over and support for either host or drive channels.

Nexsan unveils SATA II RAID
Nexsan Technologies has added the SATABoy disk array to its family of InfiniSAN storage subsystems. Notable features of the Serial ATA (SATA) II array include twice the performance of the company’s ATABoy II array, high availability, and a cache mirroring ASIC. The array can be used for primary transaction processing applications as well as long-term storage for compliance, retention, or disk-based backup applications.
The SATABoy provides 5.6TB on 14 drives in a 3U form factor. The system includes dual controllers, each of which can write at 285MBps and read at 380MBps, according to the company.
The array features active-active fail-over, two 2Gbps Fibre Channel ports, and two Gigabit Ethernet ports. The 4-port active-active configuration allows redundancy using dynamic multi-pathing applications such as Veritas’ Storage Foundation.
The SATABoy is a big brother to Nexsan’s first SATA array, the 1U SATABlade, which has eight hot-swappable SATA drives and up to 3.2TB of capacity.
Pricing for the SATABoy is approximately $3,000 per terabyte. A fully configured version with 5.6TB costs about $16,600. www.nexsan.com.
Riverbed adds ‘discontinued operation’
In the 2.0 release of its Steelhead appliances, which provide wide-area data services (WDS), Riverbed added a Proxy File Service (PFS) feature that allows the appliances to continue serving files in the event of a WAN outage. WDS, which is considered by some analysts to be a superset of wide-area file services (WAFS), provides LAN-like performance over WANs, enabling companies to consolidate remote storage resources into central data centers. PFS enables administrators to configure file shares and directories in several different ways to deliver read/write access to some files and read-only access to others. Other key enhancements in the 2.0 release include the following:
- A high-speed TCP feature (available only on the high-end Steelhead 5010 appliance) that accelerates applications such as FTP over long fat networks (LFNs) where the WAN link is very large but latency is high and throughput limited. For example, on WAN links such as OC-12 or Gigabit Ethernet, Riverbed claims that the Steelhead appliances with TCP acceleration can provide throughput in the range of 500Mbps to 700Mbps; and
- An application-level acceleration module for Microsoft SQL Server applications such as Project Enterprise.
Other additions include an optional 4-port Gigabit Ethernet NIC card (for up to 12 GbE ports on higher-end WDS appliances), IPSec encryption between appliances, and TCP connection forwarding. Steelhead appliances are priced from $7,500. www.riverbed.com.
Seagate debuts disk drives
