November 22, 2010 – A trio of RAID vendors that are focused primarily on the channel recently began shipping mid-range products, with an emphasis on multi-protocol (e.g. Fibre Channel, iSCSI, NAS) support. Here’s a quick rundown.

Infortrend announced support for both Fibre Channel and iSCSI on its entry-level EonStor DS RAID arrays. (The company’s mid-range ESVA arrays already support both protocols.) The combination of protocols enables SMBs to, for example, run mission-critical applications on a Fibre Channel SAN while using iSCSI for remote replication over Ethernet, eliminating the need for protocol converters.

The new EonStor DS “hybrid” arrays come with four 8Gbps Fibre Channel ports and two 1GbE iSCSI ports per controller, and are available in single- or dual-controller versions. Configuration options include 3U enclosures with 16 3.5-inch drives or 2U configurations with up to 24 2.5-inch drives. The systems can be scaled up to 144 6Gbps SAS drives.

Last week, Infortrend added support for thin provisioning to its entry-level EonStor DS arrays.

Thin provisioning and remote replication are currently available on the EonStor DS (ESDS) S16F-R2842, S16F-G2842, B24F-R2842 and B24F-G2842, and will be available across all EonStor DS disk arrays by the end of the month.

Also last week, Dot Hill introduced two new members in its AssuredSAN line of RAID arrays – the 3320 and 3330 – both of which include four 1GbE iSCSI ports, or eight ports in a dual-controller configuration.

The AssuredSAN 3320 includes 2.5-inch drives, while the AssuredSAN 3330 has 3.5-inch drives. OEMs, integrators and users can mix SAS, SATA and solid-state disk (SSD) drives in the same enclosure. Options included AssuredSnap and AssuredCopy data protection software. AssuredRemote replication software will be available in the first half of 2011.

Other models in Dot Hill’s AssuredSAN lineup support 8Gbps Fibre Channel, 10GbE iSCSI, as well as hybrid configurations with 8Gbps Fibre Channel and 1GbE iSCSI external connections. All of the arrays are available with 6Gbps SAS drives.

Energy-efficient features include drive spin-down and Dot Hill’s EcoStor technology, which is a battery-free alternative for cache memory that leverages a combination of super capacitors and flash memory. Dot Hill claims that its EcoStor technology can outlast traditional batteries by almost a 5X factor.

Dot Hill is currently shipping the AssuredSAN 3320 and 3330 to OEMs. Shipments to the company’s resellers are expected next month, with prices starting at $15,568.

American Megatrends (AMI) recently introduced the StorTrends 2401i disk array, which supports iSCSI IP SANs and NAS. The 2U, 12-drive arrays can be configured with SAS and/or SATA drives, and include LSI’s MegaRAID 9280 RAID controllers, two additional NIC ports and SAS expanders for JBOD attachment (up to 256TB total capacity). Software features include volume snapshots (Redirect on Write), thin provisioning, and volume replication with data deduplication, compression, encryption and WAN optimization. Options include support for 10GbE iSCSI.
