Isilon upgrades clustered storage

Isilon Systems’ IQ 12000 and EX 12000 are nodes which, when combined, create a clustered storage configuration that can scale to more than 1.6PB of capacity in a single file system and single volume.

The IQ 12000 platform node and EX 12000 extension node run Isilon’s OneFS operating system software in combination with 12 Hitachi 1TB SATA disk drives to provide 12TB of capacity per 2U node-a 25% increase in capacity per rack unit over previous versions. Customers can use the 12000 series to build a 250TB storage cluster in a single data-center rack.

The difference between the IQ and EX nodes is performance. The chassis are the same, but an EX 12000 is disk-only and lacks the performance characteristics of the IQ 12000. The IQ 12000 provides linear scaling of both capacity and performance with the addition of each modular node. The EX 12000, when paired with the IQ 12000, provides scaling of capacity independent of performance, creating a high-density configuration for storing and accessing archives of unstructured data and digital content.

EX 12000 nodes connect to IQ 12000 devices on a 1:1 basis via a SAS interconnect, essentially creating a 24TB storage node designed to support nearline storage applications.

However, taking advantage of high-capacity drive technology can be something of a double-edged sword. The knock on 1TB disk drives is the time it takes to rebuild a drive after a failure. Isilon officials claim that with traditional NAS architectures, rebuild times with 1TB drives can take 24 hours or longer, whereas Isilon’s systems can rebuild a 1TB drive in 60 to 90 minutes.

Isilon’s OneFS platform and integrated FlexProtect-AP data-protection software provide N+4 data protection, meaning a cluster can withstand up to four simultaneous failures without losing access to data.

List pricing for the IQ 12000 is $49,250 per node, while the EX 12000 is priced from $29,250 per node.

BlueArc pushes into midrange

Generally known for its high-end NAS arrays, BlueArc has introduced a version of its Titan series targeted at the midrange market. Pricing for the Titan 1100 starts at $75,000, which is about 25% less than the company’s existing entry-level system. The Titan 1100 has the same architecture (SiliconServer), firmware, and software suite as the higher-end Titan 2000 arrays.

The 1100 supports two-node clustering, a four-blade chassis, four Gigabit Ethernet ports, and four Fibre Channel ports. The systems can be clustered via two 10Gbps Ethernet ports, and each 1100 can scale up to 128TB of capacity. Software functionality includes data management, virtualization, archiving, security, disaster recovery, remote replication, and synchronous/asynchronous mirroring. Company officials position the array as a nearline/archive storage system.

Users can create “in-the-box” tiered storage with a mix of Fibre Channel and SATA drives, as well as write-once, read-many (WORM)-protected disks.

In terms of performance, BlueArc claims up to 2.5Gbps throughput and up to 50,000 I/Os per second (IOPS) based on the SPECsfs benchmark suite.

Attune teams with Data Domain

File virtualization software vendor Attune Systems has entered into a partnership with Data Domain that will give end users the ability to integrate Attune’s Maestro File Manager software with Data Domain’s de-duplicating storage systems. The two products work in tandem to create a tiered storage architecture.

Data Domain’s disk-based de-duplication systems function as targets for a range of secondary or nearline workloads, such as archiving, backup, and disaster recovery, while Attune’s file virtualization software implements policy-based file management across the storage infrastructure, allowing files to be automatically placed in predetermined tiers throughout their lifecycle.

The latest release of Attune’s Maestro File Manager software features tiered, policy-based backup enhancements and forensic file-system search capabilities across multi-vendor Windows file servers and NAS devices.

The file virtualization software gives users the ability to search the live file system or any number of point-in-time copies for files based on multiple criteria such as file owner, size, type, name, as well as storage location or modify/access date. Once discovered, files can be copied, deleted, or moved to an archive location within the file system. Files can also be non-disruptively migrated from one storage tier to another, or backed up using various backup software packages.

Data Domain also updated its software with a new version of its file system that expands the capabilities of its DDX arrays to support a range of nearline workloads beyond just data protection.

Mimosa adds DR option

Mimosa Systems has introduced a disaster-recovery option for its flagship NearPoint archiving software. Designed for Microsoft Exchange environments, the disaster-recovery option is automatic, allowing organizations to maintain uptime and application consistency. Mimosa officials claim Exchange recovery in minutes.

The NearPoint Disaster Recovery option does not require kernel drivers or agents on the Exchange server. Mimosa claims continuous data protection (CDP) at the transaction-log level, along with recovery at the database, mailbox, and message levels.

Application-intelligent recovery is designed to preserve the consistency and integrity of Exchange data by preventing replication of corrupted Exchange databases. With the disaster-recovery module, users can recover Exchange services to a local, remote, or standby Exchange server.

The NearPoint base product for 2,000 mailboxes is priced at $40 per mailbox. The disaster-recovery function costs $5 extra per mailbox. An enterprise edition is also available.

Index Engines addresses e-discovery

Enterprise search and discovery specialist Index Engines has released the eDiscovery Edition of its Tape Engine technology with a new set of features for automating the electronic discovery process for offline tape content. The eDiscovery Edition automates tape data sorting and object extraction, thereby eliminating the process of restoring tapes in order to begin data discovery. New to the platform are a tape management module that automatically generates a catalog of the tapes loaded in a library, and an automated extraction module that can retrieve relevant data without restoring tapes with the original backup software.

The eDiscovery platform is sold as a plug-and-play appliance that attaches to a tape library or drive via SCSI or Fibre Channel. The appliance’s auto-configure feature detects the connection and library type, indexes the data, and enables search. Once the data is searched and located, it is extracted onto a shared network drive.

The Enterprise eDiscovery Edition works with formats such as CA ARCServe, IBM Tivoli Storage Manager, Veritas NetBackup and Backup Exec, and Legato NetWorker. Pricing for the Enterprise eDiscovery platform starts at $50,000 for two million objects.

Teneros protects Exchange

The second generation of Teneros’ Application Continuity Appliance for Microsoft Exchange is now available as the “V”elocity series. The appliances capitalize on virtualization technology to expand data protection from the Exchange server and data to the Exchange ecosystem, including mobile messaging, Active Directory, and data backup and restore. “V”elocity appliances support 50 to 2,000 mailboxes, 90GB to multiple terabytes of capacity, and are based on a 64-bit virtual machine architecture. Pricing ranges from $7,000 to $27,000.
