Dell adds 2.5-inch SAS drives

Dell’s PowerVault MD1120 disk array features 2.5-inch small-form-factor (SFF) SAS disk drives. Although Dell has been offering both 3.5-inch and 2.5-inch drives in its PowerEdge servers for some time, the MD1120 marks the first time the company is integrating 2.5-inch SAS drives in its disk arrays.

 

 

 

 

Designed primarily for connection to Dell’s PowerEdge servers, the PowerVault MD1120 houses up to 24 SFF SAS drives per enclosure, requiring 70% less space and up to 50% less power than configurations with 3.5-inch drives. In terms of performance, the 2.5-inch drives have more than twice the I/Os per second versus 3.5-inch array configurations.

The 3Gbps SAS drives are available in 36GB and 73GB 15,000rpm models, and 73GB or 146GB 10,000rpm models.

Users can scale the MD1120 up to six enclosures, or 144 drives, via Dell’s PERC 6 RAID controllers. Total capacity ranges from 72GB to 3.5TB per enclosure, or up to 21TB in a 144-drive configuration. In a RAID configuration, the MD1120 supports up to 30 physical disks per group, or up to 64 virtual disks per controller. The arrays come with one 3Gbps SAS host connection.

The PowerVault MD1120 is priced at approximately $10,000 for a 20-drive configuration.

Seagate ships 6Gbps SAS drives

Although most 2.5-inch SFF SAS drives come in capacities such as 73GB and 146GB, Seagate recently began shipping to OEMs a 300GB SFF drive. According to Seagate, the 10,000rpm Savvio 10K.3 drives reduce power consumption by 70% and increase performance by 60% versus traditional 3.5-inch SAS drives.

The drives are among the first to support the 6Gbps SAS 2.0 interface, which improves signal and data integrity features compared to 3Gbps SAS drives.

Savvio 10K.3 drives have a mean time between failure (MTBF) rating of 1.6 million hours and come with Full Disk Encryption (FDE).

Infortrend ships FC-to-SAS/SATA arrays

Infortrend’s EonStor S12F-R1432 (dual controller) and S12F-G1433 (single controller) are 2U, 12-bay RAID arrays with 4Gbps Fibre Channel host interfaces and support for SATA and/or SAS drives. Features include RAID 5 and RAID 6; performance of up to 1,420MBps on reads and 780MBps on writes; and scalability up to 60TB via JBOD expansion units with 1TB SATA drives.

NetCom delivers SATA RAID

NetCom’s NR6 RAID array comes in 2TB, 4TB, and 8TB capacities using 1TB SATA drives and is available with PCIe or eSATA host interfaces. The company claims a data-transfer rate of up to 400MBps, and support for RAID 0, 5, 6, and 10. The arrays are compatible with Windows, Linux, and Macintosh platforms. Pricing ranges from $4,649 for a 2TB configuration to slightly less than $10,000 for an 8TB configuration. NetCom’s enclosures are manufactured by Arena Maxtronic, and its RAID controllers are supplied by Accusys.

Robobak: Online backup for $1K

Robobak has released a Standard Edition of its Version 8 Data Protection Platform, an online backup service with prices starting at $1,000 for 100GB of compressed, de-duplicated capacity (or about 200GB to 500GB of user data.) The Standard Edition is 32-bit with a capacity limit of 10TB, while the Enterprise Edition is 32-bit or 64-bit with support for virtually unlimited capacity. In terms of functionality, the two editions are virtually identical. Features include agent-less continuous data protection (CDP), compression, and data de-duplication.

Neverfail intros ClusterProtector

This month, Neverfail added a ClusterProtector enhancement to its Continuous Availability Suite. The software provides continuous data replication for Microsoft Windows Failover Clustering. Replication of application data is done in real-time over a WAN to a disaster-recovery site. The software is available for Microsoft Exchange Server, SQL Server, and Office SharePoint Server.
