ASCII.jp Brocade "VCS Virtual Fabric" is compatible with multi -tenant

On October 4, Brocade Communications Systems (hereinafter, Brocade) held a presentation on new technologies and products at the Ondemand Data Center promoted by the company.Ethernet fabric's multi -tenant compatible with the overlay alternative and the high -speed technology of the virtual router "Vyatta" were shown.

VCS fabric that strengthens multi -tenant

The Ondemand Data Center, a brocade data center concept, is based on fabric that applies the technology that the company has cultivated in SAN for many years to Ethernet.This "BROCADE VCS Fabric" is configured by clustering multiple BROCADE VDX switches, and can be managed as one logical switch.In addition, all links in the fabric are realized as active multi -pass and can be easily expanded.In addition to this, in recent years, we are actively adopting technologies such as SDN and OSS, and has been promoting automation and operation management, including the cloud.

Relationship between fabric and SDN

This time, Brocade announced the enhancement of the VCS fabric function implemented in the company's Brocade VDX switch product group.At the presentation, Kazunari Ogata, Executive Officer of Brocade Communications Systems SDN Business Development Headquarters, explained the outline of new products and technology.

The first introduced was VCS Virtual Fabric, which realizes a large multi -tenant environment.At present, L2 VLANs used to build multi -tenant networks are limited, but VRF (Virtual Routing & Forwarding) requires complexity and operation management unique to L3.On the other hand, overlay networks using VXLANs and the like have high expandability, but are new technologies and have high thresholds.

On the other hand, the VCS Virtual Fabric, which was announced this time, realizes a multi-tenant environment based on the labeling technology called "Trill Fine-Grained Labels", and "Underley Network Separation of Underley Network is separated for virtualized layers.Solution "Solution".It is characterized by its high affinity with VLANs, which has been used in the past, and can be linked with existing third -party tools.At the time of release in January 2014, it supports up to 8000 VCS Virtual Fabric, but it is logically up to 16 million.The cooperation between OpenStack and Brocade API has been strengthened, making it easier to provision from orchestrators.

Enhanced SDN compatible and storage awear network

At the same time, "BROCADE VCS Gateway for VMware NSX" was also provided, and Brocade VCS can be converted to existing VLANs and VXLAN.It should be noted that there is no overhead of conversion because it is performed with BROCADE VDX hardware.VXLAN -free servers and storage, existing appliance and overlay network nodes under VMware NSX controller can be operated in cooperation.

In addition, "VCS AUTOQOS" that enables automatic priority control of IP storage traffic (NFS and iSCSI) is also added.Initially, it is simple to handle storage traffic in fabric compared to other best effort traffic, but in the future it will add improvements so that detailed control can be performed for each tenant.

As a new hardware product, "BROCADE VDX 6740/6740T", which is equipped with 48 ports 10Gbps port and 4 40GBE QSFP +, is added to the lineup (shipped in September).A model with a fixed port of VDX 6740 SFP + and VDX 6740T is a 10GBASE-T fixed port.A wide band -up link of 160Gbps, which bundles four new 40GBEs, will be provided.In addition, it is equipped with ASIC that processes the VCS Virtual Fabric and VCS Gateway for VMware VCX, and OpenFlow is also stable..I plan to support 3.In March 2014, it was also revealed that the 100GBE module for the chassis -type switch "BROCADE VDX8770" will be shipped.

"VPLANE" architecture that realizes high -speed processing speed

Another highlight of the announcement of the VCS fabric expansion is the new model of the virtual router, Vyatta 5600 VROUTER.VYATTA VROUTER is a software router that operates on the X86 server, which is a product located at the core of the "NFV (Network Function Virtualization)" strategy that aims to virtualize various network functions such as routing, road balancing, and firewall.

The appearance of the new model, "Vyatta 5600 VROUTER", is that it has been needed for higher -speed virtual appliance with improving server performance and increasing network load.As VM implementation density increases, traffic between VMs increases.Naturally, the increase in traffic between host servers has been required, which has been required to match the 10Gbps physical interface.

However, in the case of the conventional product VYATTA 5400 VROUTER, it operates for forwarding, routing, VPN, firewall, QOS, NAT, and management with a single software and performed a single CPU.As a result, all the multi -core CPUs were not used up, and resources compete occurred, and the processing capacity for each core was also platformed.

On the other hand, the new product VYATTA 5600 VROUTER uses a "VPLANE" architecture that separates control planes and forwarding planes.By utilizing Intel's DPDK (Data Plane Development Kit), specific packet processing is assigned for each core, so that resource competition is not performed.As a result, it is a software router, but will achieve a 10Gbps throughput per X86 core and more than 10 times the performance.

By achieving such high processing performance, in addition to the use of cloud providers such as routing in the server and virtual BGP route reflector, it will be possible to satisfy the applications of telecommunications businesses such as BGP routing and ACL off -road.The image is that the router itself is virtualized for each function, and the network infrastructure of the telecommunications carrier is embedded in the right place.Open, which does not choose a hypervisor, is also sold greatly, and has a strategic advantage compared to other companies.

VYATTA 5600 VROUTER has been shipped limited and will be released to the general public by the end of 2013.

At the recital, it was also announced that the "BROCADE ADX Application Delivery Switch" was adopted in the OpenStack private cloud for Yahoo! JAPAN application development.
