Covering all the bases, Diversified Technology, Inc.'s ATS2148 is an AdvancedTCA Hub Switch blade for a dual-star fabric-based ATCA shelf incorporating an Infiniband fabric interface as well as an Ethernet switch on ATCA's base interface.
Supporting ATCA 3.2 Option 1, the ATS2148 provides fifteen InfiniBand x4 connections to the backplane, allow it to support either a 14 or 16-slot AdvancedTCA platform.
Designed for embedded data-transport applications, database clustering, and low latency embedded switching, the non-blocking, low-latency fabric switch supports all fifteen backplane ports (10 Gb/s) and three front panel ports (10 Gb/s) running at full wire speed.
The ATS2148 Hub Board provides separate control plane switching, data plane switching, and storage plane switching for ATCA shelves. It supports gigabit Ethernet on the base control network while the fabric features a 10Gb/s InfiniBand switch with built-in InfiniBand Subnet Management Agent (SMA) and Performance Management Agents (PMA.)
The fabric switch supports sophisticated subnet management, fabric discovery and initialization, and quality of service. The switch's PMA monitors fabric health and link and packet errors as well as detecting and isolating potential problems before they occur.
Multi-pathing and automatic path migration are fully supported enabling fault tolerance and failover as well as providing notification that a self-healing fabric event occurred and maintenance may be required.
The ATS2148 also features 24-port gigabit Ethernet switches for ATCA base
switching. Ports are provided to support the full 16-slot shelf with both
redundant switches and redundant shelf managers. Up to 8 uplink ports on the base can be provided for connections between shelves and to outside
The base Ethernet switch features layer 2 switching and layer 3 routing as well as advanced features such as a DHCP server, independent VLAN learning, VRRP, RIP, OSPF, rapid spanning tree, DiffServ, and access control lists among others. With support for an industry standard CLI, telnet/SSH, SNMP, RADIUS, and a web interface, the ATS1460 provides robust management.
Production shipments begin in the fourth quarter of the year, but development units will be available through DTI's beta program in August.
