Alcatel plays catch-up with 10G switches

Alcatel this week is to launch two switches targeted for corporate-backbone and data-center deployments, where Gigabit Ethernet links are either aggregated from stacks of LAN-edge switches in wiring closets or from racks of Gigabit-enabled servers.

The OmniSwitch 9700 switch is a 10-slot chassis, while the 9800 switch includes 18 slots. When configured with two redundant management modules and two fabrics, the boxes can hold as many as six and 14 service blades, respectively.

Both switches include IPv4 and IPv6 support on all port interfaces. The switch software also allows the device to tunnel IPv4 and IPv6 links together, allowing disparate networks running different versions of IP to connect. The devices come standard with full Layer 3 routing and complete protocol support - OSPF, RIP versions 1 and 2; and BGP.

The new OmniSwitches also support advanced virtual LAN (VLAN ) configurations and multicast deployments, which can be useful when running redundant clusters of servers in a data center, with non-clustered machines. Alcatel's switch software allows for Layer 2 multicast broadcasting of packet streams to one or more VLANs; this allows some servers attached to the switch to receive the replicated packets, while others do not.

The new OmniSwitches are upgrades from previous OmniSwitch 8000 series chassis, and offer more switching capacity than the previous boxes.

The switches support standard QoS at Layer 2 with 802.1p traffic prioritization. The switches can map Layer 3 Type of Service and DiffServ QoS settings to Layer 2 802.1p priority queues, which allows prioritized traffic from different networks to maintain QoS settings, Alcatel says.

Analysts say the products do not break new ground in terms of speeds and feeds. However, they do fill a void in Alcatel's high-end switching portfolio, and bring it up to the same level as competitors 3Com, Cisco, Nortel, Extreme, Foundry and others.
