VadaTech has introduced the ATC605, a Network Attached Storage (NAS) blade incorporating on-board Intel Xeon E3-1505M processing and a high-performance hardware off-load engine for iSCSI Target supporting line rates at 40GbE. The integrated back-end RAID storage subsystem can provide over 20TB of storage via four removable NVMe modules. This AdvancedTCA blade has a dual 100/40/10GbE ports to the Fabric channel as well as a 40GbE port to the up-date channel, supporting fail over across two of the ATC605 in a redundant configuration.

As defined by the open modular computing standards group PICMG, "The Advanced Telecom Computing Architecture (AdvancedTCA) specifications, denoted PICMG 3.X, are a series of PICMG specifications, designed to provide an open, multi-vendor architecture targeted to requirements for the next generation of carrier grade communications equipment. This series of specifications incorporates the latest trends in high speed interconnect technologies, next generation processors and improved reliability, manageability and serviceability."

PICMG adds that "AdvancedTCA, also known as ATCA, is the first open architecture that provides an extremely sophisticated and robust system management architecture that enables high availability systems that keep running in the event of individual component or sub-system failure."

As explained by the manufacturer, the ATC605 blade's advanced RAID On Chip (ROC) co-processor off-loads the main CPU, supporting RAID levels 0, 1, 5 and 6 with RAID spans 10, 50 and 60. In addition, the ROC checks for consistency of background data integrity, with patrol read capability for media scanning and repairing. The ROC has an optional battery pack to prevent data loss in the event of a power failure. After loss of system power, it will auto-resume during array rebuild or reconstruction. The RAID can be managed via a sophisticated GUI, running LSI Mega RAID software. The ATC605 implements the IPMI 2.0 protocol for management and payload.
