NetApp arrays support SAS

Network Appliance is shipping two new “unified storage” midrange appliances in its FAS2000 product line-the FAS2020 and FAS2050. NetApp is pitching the FAS2000 series as a platform for companies migrating from DAS to networked storage. The appliances run NetApp’s Data ONTAP operating software.

The FAS2000 arrays combined with Data ONTAP provide snapshot technology, RAID-DP (RAID-6) data protection, A-SIS data de-duplication technology, FlexClone cloning software, and FlexVol thin-provisioning software. The systems also support management software such as SnapManager for Exchange, Oracle, SAP, SharePoint, and SQL Server.

The FAS2020 has a maximum capacity of 24TB using external 750GB SATA drives. The FAS2050 can scale up to 69TB with 750GB SATA drives. Both appliances support CIFS and NFS, IP SANs, Fibre Channel SANs, and Fibre Channel tape environments.

The FAS2020 and FAS2050 are replacements for the FAS250 and FA270, respectively. The new disk arrays also mark the first time NetApp has incorporated SAS technology into its product line.

Users can mix SAS, SATA, and Fibre Channel drives in the same system, but NetApp does not recommend mixing drive types within RAID volumes or fail-over loops within HA environments.

The starting price for a base configuration of a FAS2020 system is $12,100, while the FAS2050 is priced from just under $25,000. Pricing includes Data ONTAP, RAID-DP, Snapshot, FlexVol, iSCSI protocol software, and 1.75TB of raw storage.

NetApp also expanded its reseller relationship with IBM to include the new products. Big Blue is now reselling NetApp FAS2000 systems as the re-branded IBM N3000 systems.

Dell, IBM, Adaptec add iSCSI arrays

Adding to its Dell/EMC AX150i line of iSCSI disk arrays (and causing a bit of confusion over the relative positioning of its IP SAN arrays), Dell recently began shipments of the iSCSI-based MD3000i.

The MD3000i is available in single-controller or active-active controller versions supporting up to four Gigabit Ethernet connections and up to 15 3.5-inch SAS disk drives (10,000rpm or 15,000rpm) in capacities of up to 400GB. Maximum capacity is 18TB with two expansion enclosures and a total of 45 SAS drives. The disk array includes multi-path software for fail-over, as well as optional data-protection features such as Virtual Disk Snapshots (up to four snapshots per virtual disk or 128 snapshots per system) and Virtual Disk Copy (up to eight simultaneous copies).

In the fourth quarter, Dell plans to add support for SATA drives in capacities from 250GB to 1TB, with the ability to mix SATA and SAS drives in the same enclosure.

The MD 3000i supports RAID 0, 1, 5, and 10, with up to 30 physical disks per disk group and up to 256 virtual disks. Each controller comes with 512MB of cache memory.

The iSCSI array supports Windows 2003 and Linux, including RedHat 4.0 and SuSE.

Pricing for the MD3000i ranges from $8,000 to $20,000.

IBM has also added an iSCSI disk array to its lineup. The System Storage DS3300 is the newest addition to the DS3000 series of entry-level storage arrays.

The disk array features SAS disk drives and Simplicity management software with installation wizards to guide administrators through setup and configuration.

The DS3300 supports up to 14.4TB of raw capacity with SAS drives and the EXP3000 expansion unit.

Users can also include optional data-protection features, including FlashCopy for point-in-time, full-volume copies of data, and VolumeCopy for full logical drive replication.

The DS3300 is priced from $5,000.

In addition, IBM announced two new Express models based on the DS3400 Fibre Channel array. The DS3400 systems comprise SAN16B-2 switches from Brocade and 4Gbps Fibre Channel-to-PCI-E host bus adapters (HBAs) from Emulex.

The DS3400 Express models have been certified in the Microsoft Simple SAN Solution program, which was developed to provide users with a simplified SAN installation and management process.

IBM is also working with Emulex to deliver a management software tool called EZPilot to streamline the configuration process of the DS3400 Express Kit. EZPilot ties together management functions for the DS3400 array, the Brocade switch, and Emulex HBAs.

Adaptec recently introduced the Snap Server 700i series of iSCSI storage appliances, hoping to differentiate the arrays from competitors’ largely on the basis of price/performance. Don Chouinard, director of product management and marketing in Adaptec’s Storage Solutions Group, cites EMC/Dell, Equal-Logic, Hewlett-Packard, LeftHand Networks, and Network Appliance as the company’s primary competitors in the iSCSI space.

The 700i is designed to allow medium-sized companies running Linux, VMware, or Windows servers to deploy an IP SAN. The 700i series includes three 1U rack-mount models and provides 1TB to 3TB using SATA drives. Users can mix both SATA and 15,000rpm SAS drives.

Users can add capacity via Adaptec’s 2U SANbloc S50 expansion chassis, each of which can be configured with any combination of 12 hot-swappable SATA or SAS drives. The 700i series can scale up to 45 SAS disks or 100 SATA disks.

The 700i can be managed with Adaptec Storage Manager software, which handles grouping, assigning RAID levels, carving LUNs, and masking servers. The systems are compatible with Microsoft’s Virtual Disk Service (VDS).

Automatic Storage Provisioning helps users create disk pools, assign RAID levels and iSCSI LUNs, set up iSCSI initiators, and format operating system partitions. Wizard-based management reduces setup time and ongoing maintenance/administration.

Application-consistent snapshots can be taken for backups using Microsoft’s Volume Shadow Copy Service (VSS) technology. If the user has a volume on one 700i and one on another 700i, they can be tied in a set and snapped together. Other features include synchronous mirroring, multi-pathing, and support for virtually all RAID levels. The systems are powered by Adaptec’s Linux-based OnTarget operating system.

The Snap Server 700i series includes the 720i ($8,000 with 1TB of SATA capacity or $9,600 with 2TB); the 730i ($13,400 for 3TB of SATA capacity); and 750i ($23,300 with 1.2TB of SAS capacity).

Atto enhances iSCSI for Macs

Version 3.0 of Atto Technology’s Xtend iSCSI initiator software supports Mac OS X software and OS X workstations. Features include support for Challenge-Handshake Authentication Protocol (CHAP), which is the primary authentication/security mechanism for IP SANs; support for Internet Storage Name Service (iSNS), which provides automated discovery, management, and configuration of iSCSI devices; and a Login Redirect feature for increased availability and reliability.

Promise ships 16-bay SAS RAID

New additions to Promise Technology’s E-Class of disk subsystems-the VTE610fD and VTE610sD-are 3U, 16-bay RAID subsystems that can be configured with either SAS or SATA drives. Users can add capacity via the company’s VTJ610sD expansion chassis. With four chassis, the systems support 166,000 I/Os per second (IOPS) and up to 80TB of capacity in an all-SATA configuration. Other features include dual controllers, support for all RAID levels, 512MB to 2GB of battery-backed cache, and hot-swappable power supplies and cooling modules.

Enhance supports SAS

Enhance Technology’s UltraStor RS16 SS is a 3U, 16-bay RAID array with support for RAID 6 (dual-parity RAID) and all other RAID levels, 3Gbps SAS disk drives and SATA drives, and dual SAS host connections. The company claims a data-transfer rate in excess of 800MBps. The system can be configured with up to 16TB (using 1TB SATA drives) or up to 4.8TB with 300GB SAS drives. Pricing starts at $4,950 without disk drives.

Sans Digital ships SATA JBOD

Sans Digital’s TowerRAID series now includes the TR4M SATA-to-JBOD enclosure and TR4U SATA-to-USB JBOD/spanning enclosure. The TR4M is a four-bay unit that has up to four SATA drives, a port multiplier feature, and a 2-port eSATA PCIe card. In addition to JBOD, the array supports virtually all RAID levels. The TowerRAID TR4U JBOD or spanning enclosure connects to USB 2.0 interfaces

Overland increases VTL capacity

Overland Storage’s REO 4500c virtual tape library (VTL) has up to 27TB of raw capacity, hardware compression (for up to 45TB), dual 4Gbps Fibre Channel and iSCSI host connectivity, and up to six VTLs, 32 virtual tape drives, 512 virtual cartridges, and 16 initiators. MSRP pricing starts at $36,155.
