CISCO WAAS ARCHITECTURE HARDWARE AND SIZING PDF

Save Digg Del. The Cisco Wide-Area Application Engine family includes three network modules for the Integrated Services Router and six appliance models spanning two desktop models and four rack-mount appliance models. This breadth of portfolio provides customers with the flexibility necessary to allocate the right platform for each network location where WAN optimization, application acceleration, and virtualization capabilities are needed. Sizing of a Cisco WAAS solution requires consideration of a number of factors, including network conditions WAN bandwidth and LAN throughput , number of users and concurrent optimized TCP connections, disk capacity and compression history, memory, concurrently connected peers, and virtualization requirements.

Cisco WAAS helps enable organizations to implement important business initiatives, including:. Cisco is the leader in WAN optimization, as confirmed by IT professionals from both Nemertes Research and IT Brand Pulse, for leadership in overall market, price, performance, reliability, service and support, and innovation.

Cisco WAAS virtualization is scalable, highly secure, and robust, enabling migration to cloud-based services. Adding vPath 2. Print Application Optimization AO enhancements. The vWAAS model establishes Cisco as an industry leader in the number of maximum connections with a lower price per connection.

However, for new deployments only a single OVA file will be released that supports 5. Upgrade and install instructions can be found through existing WAAS update information below. Table 1.

The vPath service chaining feature allows virtual machine VM traffic to be treated by multiple services in a given sequence.

Increasingly, many customers are consolidating print servers at the headend or aggregation point. These include compliance, end-of-life extension, operation efficiency, savings in capital expenditures CapEx and operating expenditures OpEx, network agility, etc. Virtual desktop infrastructure VDI places an increasing burden on the WAN because application performance, security, and manageability expectations need to be maintained as work shifts to a VDI environment, increasing the pressure on IT to deploy an agile and optimized WAN.

Organizations such as the U. To facilitate this cloud-based model, a WAN optimization solution should be able to intelligently pool and provision resources elastically in a simplified manner with excellent manageability for enterprisewide deployments.

Therefore, a WAN optimization solution must be transparent and jointly validated and supported by leading industry vendors. Security standards continue to evolve in response to increasing numbers of compromised systems. The WAN must not only optimize applications and data, but also protect them.

It provides the most choices for WAN optimization with the broadest portfolio on the market today. This approach makes better use of existing investments while offering business agility. Cisco vWAAS employs policy-based configuration in Cisco Nexus V Series Switches, which allows association with application server virtual machines as they are instantiated or moved.

It does so in situations in which neither an appliance nor a branch office router is available or practical, and in public cloud environments that cannot support an appliance. Customers can add capacity or dedicate capacity to specific applications or geographies based on business requirements with no change to existing network configurations or topologies. Cisco AppNav integrates transparently into any physical or virtual network infrastructure, providing significant investment protection for existing network designs.

Validated designs assist Cisco customers by offering best practices to successfully incorporate IT infrastructure such as Cisco switches, routers, security devices, and servers, thus significantly reducing the risk of deploying WAN optimization to accelerate these applications.

Coupled with award-winning Cisco global support and advanced services, Cisco WAAS gives customers a significant set of resources to help ensure full network integration while reducing maintenance costs and deployment time. For example, with Microsoft, Cisco has developed an optimized branch office architecture that uses Cisco WAAS to optimize performance of centralized applications such as Microsoft Exchange, SharePoint, and file services.

Cisco WAAS transparent architecture helps enable integration into the network and preservation of existing network services, thereby making WAN acceleration easy to deploy and operate. Table 3.

Simplified Central Management and Monitoring. Scalability and High Availability. Cisco WAAS offers the following licenses based on feature capabilities:. It offers automated edge-stream splitting to help ensure that only one video stream is downloaded over the WAN regardless of the number of users in the branch office viewing that stream.

Cisco offers a wide range of services programs to accelerate customer success. These innovative services programs are delivered through a unique combination of people, processes, tools, and partners, resulting in high levels of customer satisfaction. Cisco Services offerings help you protect your network investment, optimize network operations, and prepare the network for new applications to extend network intelligence and the power of your business.

These features improve end-user application response times, significantly improving employee productivity. The wizard includes defaults for faster deployment.

Diagnostic and troubleshooting tools help reduce mean time to resolution MTTR. This capability helps enable cloud providers to offer rapid delivery of WAN optimization services with little network configuration or disruption to achieve a cloud consumption and delivery model. Sizing benchmarks and performance metrics provided on the Cisco UCS platform result in lower risk for cloud deployments.

In addition, Cisco WAAS Mobile can be used to accelerate access to hosted infrastructure-as-a-service IaaS applications delivered from public cloud platforms, such as Amazon. This architecture maintains native performance for WAN optimization while using the same hardware platform for additional hosted services.

Policy-based routing PBR is also supported as a deployment mechanism. The inline option provides high scalability and active-active failover through daisy-chain clustering. No additional domain security or user configuration is necessary. No other vendor currently preserves security for accelerated traffic.

Cisco Wide Area Application Services Configuration Guide (Software Version 5.4.1)

Save Digg Del. Cisco WAAS is a software component that is resident on a hardware device deployed at each location with users and servers. The distinction between the two is that a WAVE device, available only as an appliance, can also provide branch office virtualization services in conjunction with WAN optimization and application acceleration. WAE devices provide only WAN optimization and application acceleration and do not provide virtualization. This chapter provides an introduction to the Cisco WAAS hardware family, along with an in-depth examination of the hardware and software architecture.

Cisco Wide Area Application Services Configuration Guide (Software Version 4.1.3)

This chapter provides an overview of the Cisco WAAS solution and describes the main features that enable WAAS to overcome the most common challenges in transporting data over a wide area network. When client and server applications attempt to communicate with each other, the network intercepts and redirects this traffic to the WAEs so that they can act on behalf of the client application and the destination server. The WAEs examine the traffic and use built-in application policies to determine whether to optimize the traffic or allow it to pass through your network unoptimized. Intelligent protocol adapters reduce the number of roundtrip responses common with chatty application protocols. Data caching provided with the file services feature and data compression reduce the amount of data sent over the WAN, which increases data transfer rates. These solutions improve application response time on congested links by reducing the amount of data sent across the WAN.
