Silver Peak boosts WAN performance
As the amount of data moving across WANs continues to grow, vendors keep rolling out new tools for maximizing the performance of applications over distances. WAN acceleration appliance vendor Silver Peak Systems is the latest vendor to enhance its products in an effort to help companies get more bandwidth for their IT buck.
The company has introduced version 2.0 of its Silver Peak management software for its family of NX acceleration appliances and Global Management System (GMS).
The new software includes various performance upgrades to the company’s Network Memory technology, along with a number of tools that simplify configuration and deployment of Silver Peak’s WAN acceleration systems.
Network Memory data-reduction technology reduces WAN traffic and accelerates application performance. Network Memory adds less than 1ms of latency and works with all types of applications, including real-time data replication, interactive SQL transactions, and streaming video.
Silver Peak’s NX Series appliances sit between network resources and the WAN infrastructure and employ a variety of latency and loss mitigation techniques, compression, and quality of service (QoS) to improve application performance.
The GMS platform is used to deploy, manage, and monitor Silver Peak-enabled WANs. GMS gives IT managers visibility into applications, including WAN performance statistics, application analysis, and tools for configuring and managing NX Series appliances.
The Silver Peak 2.0 software features new pattern recognition capabilities and faster reads and writes to disk over WANs, a centralized policy engine for easier configuration and management of QoS, routing and optimization policies, new traffic management policies, application optimization techniques, and auto-configuration capabilities.
Ciprico branches out
Known primarily as a storage systems vendor focused on the entertainment market, Ciprico hopes to branch out beyond its traditional roots into the mainstream IT storage market. The seeds for the expansion were planted last year with the company’s acquisition of certain RAIDcore products from Broadcom, including host-based RAID software.
Targeted at OEMs and systems-storage integrators and VARs, Ciprico’s RAIDCore RC5000 line of SAS/SATA RAID controllers are available in 4- or 8-port configurations for PCI-X or PCI Express hosts (Windows or Linux). The company plans to ship 12- and 16-port versions in the third quarter. Also due later this year is support for Intel and nVidia motherboards as part of Ciprico’s upcoming Universal RAIDCore software stack.
The company claims performance of more than 1.1GBps with 16 SATA drives, based on lab results. Using spanning algorithms, integrators can create virtual arrays of up to 32 drives.
But Ciprico’s real “secret sauce” may lie in its host-based RAIDCore software stack. (Since the RAID logic resides in the software, rather than the hardware, Ciprico’s RAID controllers could more accurately be described as host bus adapters.)
The host software stack eliminates the need for embedded processors or custom RAID chipsets on the controller/adapter. Instead, the software-based RAID approach uses host CPU cycles for RAID calculations.
Avnet and Bell Microproducts distribute RAIDCore controllers/adapters and software. Pricing ranges from about $219 to $299. Pricing for the upcoming 12-port and 16-port versions is expected to be $519 and $679, respectively.
Adaptec enhances NAS software
The 4.4 version of Adaptec’s Guardian-OS software, which runs on the company’s Snap Server NAS appliances, includes new features such as
- A Data Migration Utility enables users to copy data, including security permissions, from any system supporting CIFS or NFS to a Snap Server;
- Support for USB print servers and tape drives, with integrated NetVault software from BakBone;
- Enhanced iSCSI support for up to 255 LUNs; and
- Snap Enterprise Data Replication (EDR) software.
Snap Server NAS appliances currently scale from 160GB to 66TB.
Reldata upgrades virtual OS
Reldata has enhanced its storage virtualization software, RELvos Version 2.0, with 64-bit performance designed to boost the throughput of the company’s “unified storage systems.”
The RELvos Virtualization Operating System provides unified-block-level iSCSI SAN and file-level NAS-storage services. The combination of Reldata’s 9000 series of virtualization appliances and RELvos software lets organizations expand both IP SAN and NAS capacity to meet user demand, consolidate under-utilized storage assets, and ensure data availability via replication.
The RELvos block-level SAN virtualization platform provisions parallel and concurrent iSCSI targets and NAS file systems. The iSCSI requests are processed at the block level and they bypass file system virtualization to improve performance. The platforms support RAID 1, 4, 5, and 6 and provision RAID 0 as virtual volume striping to provide high performance and capacity utilization for connected storage. RELvos also allows unlimited block-level volume snapshots and snap “clones” for recovery over WANs.
Reldata claims performance of more than 300Mbps. MSRP for the 9240 Unified Storage Gateway with RELvos V2.0 is $34,485 for a fully loaded appliance.
Overland doubles VTL performance
Overland Storage recently began shipping the REO 9100 virtual tape library (VTL), which boosts the performance of its predecessor by 2x. Features include Dynamic Virtual Tape technology (intelligent provisioning for optimizing capacity utilization), dual 3Ware SATA RAID-5 controllers, 4Gbps Fibre Channel or iSCSI host connectivity, and support for up to 66TB of capacity, 32 virtual tape drives, 180 virtual cartridges, and four library partitions. Pricing starts at $28,041 from Overland’s channel partners.
MonoSphere manages EMC arrays
MonoSphere has added deeper support for capacity management and planning in EMC storage environments with the launch of Storage Horizon 3.2, a tool that maps storage usage from application hosts down to storage subsystems.
Storage Horizon now supports EMC’s Clariion product family and Symmetrix replication tools, including Business Continuance Volumes (BCV) and Symmetrix Remote Data Facility (SRDF). Storage Horizon 3.2 maps the associations between host volumes and their RAID levels, storage array logical devices and their RAID levels, and replication levels supported by BCV and SRDF, to determine current/forecasted usage of arrays.
MonoSphere’s aim is to give administrators more- accurate information about storage allocation and utilization, with an eye toward reclaiming unused capacity and ultimately making better purchasing decisions. According to the company’s test results, the information provided by Storage Horizon 3.2 can help users cut capacity purchases by as much as 50%.
The software automates data collection, forecasting, analysis, and storage capacity management. The software automatically develops capacity plans and analyzes heterogeneous storage infrastructures to determine areas of over-provisioning, under-provisioning, and unused storage. Pricing for Storage Horizon 3.2 is based on the number of terabytes managed.
