Iomega continues NAS push
Providing up to 1.44TB of RAID-5 capacity, Iomega's latest additions to its network-attached storage (NAS) appliances—the P800m and P850m—are based on Windows 2000 and include the Distributed File System (DFS), Active Directory Services (ADS), Persistent Storage Manager (PSM), File Replication Service (FRS), and Storage Resource Manager (SRM) software. Iomega claims a 3x performance improvement over its earlier NAS filers.
Common features include hot-swappable components (power supplies, fans, and drives), dual 2.4GHz Xeon CPUs with Hyper-Threading technology, software-based RAID, dual Gigabit Ethernet ports, and dual Fast Ethernet ports. Notably, in the P850m one of the Gigabit Ethernet cards is an Alacritech TCP/IP Offload Engine (TOE), which Iomega claims provides a 20% performance improvement while offloading host CPU processing. (For more information about TOEs in NAS servers, see "TOEs gain foothold in NAS market," InfoStor, March 2003, p. 8.)
The P800m (which is priced from $12,499 for 960GB) has dual Gigabit Ethernet interfaces, and the P850m (priced from $17,499 for 1.44TB) has one Gigabit Ethernet interface and one Gigabit Ethernet Alacritech card. Both models come in a 2U form factor and include eight 7,200rpm IDE/ATA disk drives and an Ultra160 SCSI interface for tape backup. Iomega's NAS appliances use 3ware's Escalade 7500 controllers, which are based on a switching architecture. www.iomega.com.
FIA expands NAS filers
FIA is shipping the POPnetserver 4600 NAS device with capacities ranging from 160GB to 1TB in a 1U form factor. The 4600 uses a 400MHz bus to support Intel's Celeron and Pentium 4 processors. It includes four hot-swappable drives, RAID, and support for local tape backup using the Ultra160 SCSI interface. Prices start at $1,699 for 160GB, and $4,599 for 1TB. www.popnetserver.com.
Xtore introduces 1U enclosures
At last month's Networld+Interop show, Xtore Extreme Storage unveiled a 1U (1.75 inches) "white box" storage enclosure that includes RAID controllers from Accusys. The USTOR enclosure can be configured with ATA disk drives for a capacity of up 2TB. Host interface options include SCSI or Fibre Channel, and configuration options include RAID 0, 1, 0+1, 3, 5, and JBOD. Power supplies and drive bays are hot-swappable. www.xtore-es.com.
Start-up ships 'Virtual Storage Gateways'
FibreStream Inc., a start-up based in Minneapolis, has begun shipments of a Virtual Storage Gateway that combines snapshots, file serving (NAS), and block serving (SAN) in a single appliance. The device plugs into Ethernet LANs and supports standard NAS protocols such as NFS and CIFS, as well as the iSCSI protocol for block-level I/O over TCP/IP networks.
The VSG can be configured with internal RAID storage using ATA disk drives, and/or can attach to external SCSI, Fibre Channel, or iSCSI disk arrays on the back-end. Storage is organized into volumes that can be formatted with a journaling file system for NAS file serving, or data can be retained in block format for Ethernet-based SAN serving. A 1TB configuration is priced at just under $22,000. www.fibrestream.com.
BakBone upgrades backup/restore software
At the Storage Networking World conference last month, BakBone Software introduced the 7.0 version of its NetVault backup-and-recovery software. Key features include
- Policy-based job management tied to event notification;
- Auto-discovery and auto-configuration features for faster installation;
- User-level access controls, which allows administrators to define users based on "privileges";
- Enhanced reporting and report editing capabilities;
- Features designed specifically for NAS and SAN environments, including a DirecSAN function that allows users to share libraries between multiple nodes to distribute backup operations;
- NDMP support;
- Disk-to-disk backup enhancements (the software writes in the same format to either tape or disk); and
- Optional client encryption for data security.
NetVault 7.0 is available on Unix, Linux, and Windows NT/2000 platforms, with pricing starting at $695. A 45-day demo version is available at www.bakbone.com.
Arkivio management software supports Unix
Arkivio has added support for Unix to its auto-stor data resource management software. (The package already supports Windows.) The software enables automated, agent-less discovery, monitoring, and reporting of data and storage resources in heterogeneous DAS, SAN, or NAS environments. Administrators can monitor capacity (available and used) and data usage patterns. www.arkivio.com.
