Quick Take: AristaNetworks Announces vEOS for vNDS

August 30, 2009

Arista Networks – the Menlo Park, CA “cloud networking solutions” company – has announced the first competitor to Cisco’s Nexus 1000V virtual, distributed switch for VMware’s vSphere. Called simply vEOS (aka Virtualized Extensible Operating System) the virtual machine application integrates into the VMware vNetwork Distributed Switch (vNDS) framework to accomplish its task.

The current advantages posed by the vNDS architecture are preservation of a VM’s network state across vMotion events and port configuration simplicity. Enhancements for the vEOS virtual machine will include QoS (with TX/RX limiting), ACL enforcement (when used with Arista’s 7000 series switch family), CLI configuration and management, distributed port profiles, port profile inheritance, VMware port mirroring, SNMP v3 RW, syslog exports, active standby control plane, SSH/telnet access to CLI, “hitless” control plane upgrades, non-disruptive installation and integrated vSwitch upgrade workflow.

Another advantage of vEOS for adopters of Arista’s 7000-series 10Gbase-T switches is its derrivation from the switch’s own EOS code base. The EOS image is monolithic with respect to feature set, so there are no “trains to catch” for compatibility, et al. Michael Morris from NetworkWorld has an article about the vEOS announcement along with some additional information about Arista’s plans and how to get your hands on a beta version of vEOS… See Arista’s official press release about vEOS.

SOLORI’s Take: While CNA’s are great, 10Gbase-T provides a less “process disruptive” access to greater network bandwidth. Arista’s move with vEOS is challenging both Cisco’s presence in the VMware market and its vision for network convergence. Just like Ethernet won-out over “superior” technologies based on its simplicity, we’re looking at 10Gbase-T’s drop-in simplicity (CAT5e support, 100/1G/10G auto-negotiate, etc.) to drive obvious market share for related products. With the 2010 battle lines drawn in the virtualization platform market, the all-important network segment will be as much a scalability factor as it is a budgetary one.

When using the coming “massive” virtualization potential of 2P/4P hardware being released in 2010 (see our Quick Take on 48-core virtualization) the obvious conduit for network traffic into 180+ VM consolidations is 10GE. The question: will 10Gbase-T deliver order-of-magnitude economies of scale needed to displace the technical advantages of DCE/CNA-based networking?


Quick Take: Vyatta Takes Virtual Networking to Cloud

June 22, 2009

Earlier this month, Vyatta announced completion of its Series C round of financing resulting in US$10M in new capital led primarily by new partner Citrix. Vyatta provides an open source alternative to traditional networking vendors like Cisco – providing software and hardware solutions targeted at the same routing, firewall and VPN market otherwise served by Cisco’s 2800, 7200 and ASA line of devices. Its software is certified to run in Xen and VMware environments.

In a related announcement, Citrix has certified Vyatta’s products for use with its Citrix Cloud Center (C3) product family to “make it as easy as possible for service providers and enterprises to use Vyatta with Citrix products such as XenDesktop, XenApp, XenServer and NetScaler.” With the addition of Citrix Delivery Systems Division GM Gordon Payne to the Vyatta board of directors, the now “closer coupling” of Citrix with Vyatta could accelerate the adoption of Vyatta in virtual infrastructures.

SOLORI’s Take: We’ve been using Vyatta’s software in lab and production applications for some time – primarily in HA routing applications where automatic routing protocols like OSPF or BGP are needed. Virtualizing Vyatta provides additional HA capabilities to cloud environments by extending infrastructure migration from the application layer all the way down to layer-3. In applications where it is a good fit, Vyatta provides an excellent solution component for the 100% virtualized environment.
