SANTA CLARA, Calif. -- Amplidata introduced its first product today, the AmpliStor object storage system consisting of a controller, storage node and monitoring software for cloud storage and archiving of large digital data and online media applications.
Amplidata's product launch came during the second day of the Storage Networking World (SNW) Spring 2011 show.
The AmpliStor AS20 storage node and AmpliStor controller use Amplidata's BitSpread core intellectual property for unstructured data. BitSpread takes objects from the application, runs them through a controller and splits them into sub-blocks. Amplidata's BitDynamics software -- an out-of-band agent used for disk monitoring and health -- scrubs, verifies, self-heals, repairs and optimizes data on disks.
The sub-blocks are encoded, meaning they're mathematically transformed into rules, with an algorithm to create redundancy. The encoded sub-blocks are then spread across the storage nodes and disks to create fault tolerance. The system is policy based, so the customer determines how many drives the sub-blocks can be spread out across the nodes or drives, said Paul Speciale, Amplidata's vice president of products.
"Amplidata uses erasure code base and eliminates the whole concept of RAID," said Marc Staimer, president at Dragon Slayer Consulting. "Instead of storing blocks in RAID, they store data in linear equations so you don't have to rebuild your data. It's just there. Because they use erasure codes, you get more usable storage with every drive and you don't suffer performance degradation that you get during drive rebuilds."
The AS20 1U rack-mount chassis contains up to 10 SATA disk drives and holds 20 TB of capacity on the back end. It has single or dual Gigabit Ethernet (GbE) network interfaces and is powered by Intel Atom processors. The controller node sits on the front end and is powered by dual, six-core processors and two 10 GbE interfaces. Amplidata claims a standard configuration of 16 drives can tolerate four disk drive failures without any data loss.
The controller uses object-based interfaces such as http/REST API, C language APIs and Python CLI. This allows AmpliStor services to be used natively from web-based online application through scriptable Command Line Interface (CLI) or embedded in VAR and OEM applications. A spin-off of the Belgium-based Incubaid, Amplidata officially came out of stealth in late 2010.
Riverbed teams with Nirvanix, supports more cloud backup software tools
Riverbed Technology Inc. said its Whitewater cloud backup appliance supports the Nirvanix Storage Delivery Network (SDN) public storage cloud and EMC NetWorker, Quest Software vRanger and CA ARCserve backup tools. Riverbed first unveiled the Whitewater backup and archive appliance in November with support for cloud providers EMCs Atmos, AT&T Synaptic Storage as a Service and Amazon S3, and backup applications Symantec NetBackup and Backup Exec and IBM Tivoli Software. Whitewater deduplicates and encrypts data and sends it to the cloud.
Avere expands NAS acceleration appliances platform
Avere Systems Inc. has added the FXT 2550 and FXT 2750 to its family of NAS acceleration appliances. The new appliances use Intel Xeon quad-core processors and more capacity on the DRAM storage tier than previous FXT systems, and include six Gigabit Ethernet (GbE) ports and dual 10 GbE ports. The FXT 2550 includes 72 GB of DRAM, 1 GB of NVRAM and 3.6 TB of high-performance SAS disk for $72,500. The FXT 2750 features the same configuration but substitutes the SAS disk tier for 512 GB of single-level cell (SLC) solid-state storage for $82,500.
Hewlett-Packard adds backup performance monitoring
Hewlett-Packard (HP) Co. today upgraded its HP Data Protector backup software, adding granular recovery support for VMware along with a backup performance monitoring and performance application called HP Data Protector Reporter. The new application shows administrators the success level of backups and recoveries. It includes 35 preconfigured reports, and tells admins if backups have been completed, when a restore occurred and if they met their service-level agreements (SLAs).
HP also added the Storage Essentials Backup Manager plug-in for HP Data Protector to combine performance monitoring for primary and secondary data. Other additions to Data Protector include support for HP 3PAR devices, Ibrix X9000 NAS and high-end P9500 arrays.
SGI, Virident combine on SSD system
SGI said it's packaging Virident tachIOn PCIe cards with its Rackable C1103 server to speed performance. SGI said customers can achieve 1 million IOPS with two tachIOn cards in a 1U C1103. The tachIOn SSD cards come in usable capacities of 300 GB, 400 GB, 600 GB and 800 GB, each in a single-slot PCIe card.
Oracle ZFS storage more compatible with other Oracle products
Oracle expanded the integration of its Sun ZFS Storage Appliance with other Oracle products. The ZFS appliance now directly connects to the Oracle Exadata Database Machine's InfiniBand fabric to accelerate backup and recovery time. The Oracle Virtual Desktop Infrastructure provides rapid iSCSI provisioning and automated desktop provisioning with the ZFS appliance, and Oracle Secure Backup is qualified for the ZFS appliance backup and recovery with Oracle's StorageTek tape libraries.
Virsto Software unveils virtual desktop product
Virsto Software introduced its Virsto Virtual Desktop Infrastructure (VDI), a hypervisor-based storage virtualization product the vendor claims can boost I/O performance and drastically reduce storage consumption of a virtual desktop. Virsto VDI is a software hypervisor plug-in that supports Citrix XenDesktop and Microsoft VDI running on Windows Server 2008 R2 Hyper-V.
Arkeia goes GA with dedupe backup
Arkeia Software made its Network Backup 9.0 software generally available, with its progressive deduplication technology, two-phase backup for shorter backup windows and agent-side AES-256 encryption. Arkeia can deduplicate data at the source or target.
