data center architecture

Full-time . Figure 1-5 shows a logical view of a server cluster. Data center services for mainframes, servers, networks, print and mail, and data center operations are provided by multiple service component providers under the coordination of a single services integrator. The layered approach is the basic foundation of the data center design that seeks to improve scalability, performance, flexibility, resiliency, and maintenance. •Back-end high-speed fabric—This high-speed fabric is the primary medium for master node to compute node and inter-compute node communications. Today, most web-based applications are built as multi-tier applications. The advantage of using logical segregation with VLANs is the reduced complexity of the server farm. The data center industry is preparing to address the latency challenges of a distributed network. GE attached server oversubscription ratios of 2.5:1 (500 Mbps) up to 8:1(125 Mbps) are common in large server cluster designs. Security is improved because an attacker can compromise a web server without gaining access to the application or database servers. Edge computing is a key component of the Internet architecture of the future. insert data). It represents the current state. The system sends notifications known as trigger and data to the clients when changes occur in the data. Job Highlights. For example, the cluster performance can directly affect getting a film to market for the holiday season or providing financial management customers with historical trending information during a market shift. TCP/IP offload and RDMA technologies are also used to increase performance while reducing CPU utilization. •Jumbo frame support—Many HPC applications use large frame sizes that exceed the 1500 byte Ethernet standard. The data-store alerts the clients whenever there is a data-store change. The main purpose of this style is to achieve integrality of data. The multi-tier model relies on security and application optimization services to be provided in the network. The following applications in the enterprise are driving this requirement: •Financial trending analysis—Real-time bond price analysis and historical trending, •Film animation—Rendering of artist multi-gigabyte files, •Manufacturing—Automotive design modeling and aerodynamics, •Search engines—Quick parallel lookup plus content insertion. It is more vulnerable to failure and data replication or duplication is possible. Due to the limitations of A central data structure or data store or data repository, which is responsible for providing permanent data storage. •Scalable fabric bandwidth—ECMP permits additional links to be added between the core and access layer as required, providing a flexible method of adjusting oversubscription and bandwidth per server. This is typically an Ethernet IP interface connected into the access layer of the existing server farm infrastructure. The server cluster model is most commonly associated with high-performance computing (HPC), parallel computing, and high-throughput computing (HTC) environments, but can also be associated with grid/utility computing. Switches provide both Layer 2 and Layer 3 topologies, fulfilling the various server broadcast domain or administrative requirements. •GigE or 10 GigE NIC cards—The applications in a server cluster can be bandwidth intensive and have the capability to burst at a high rate when necessary. The serversin the lowest layers are connected directly to one of the edge layer switches. Figure 1-4 shows the current server cluster landscape. Figure 1-3 Logical Segregation in a Server Farm with VLANs. Although Figure 1-6 demonstrates a four-way ECMP design, this can scale to eight-way by adding additional paths. This approach is widely used in DBMS, library information system, the interface repository in CORBA, compilers and CASE (computer aided software engineering) environments. Consensus about what defines a good airport terminal, office, data center, hospital, or school is changing quickly and organizations are demanding novel design approaches. The following section provides a general overview of the server cluster components and their purpose, which helps in understanding the design objectives described in Chapter 3 "Server Cluster Designs with Ethernet.". All clusters have the common goal of combining multiple CPUs to appear as a unified high performance system using special software and high-speed network interconnects. 10GE NICs have also recently emerged that introduce TCP/IP offload engines that provide similar performance to Infiniband. Designing a flexible architecture that has the ability to support new applications in a short time frame can result in a significant competitive advantage. Data-centered architecture consists of different components that communicate through shared data repositories. •Non-blocking or low-over-subscribed switch fabric—Many HPC applications are bandwidth-intensive with large quantities of data transfer and interprocess communications between compute nodes. … Such a design requires solid initial planning and thoughtful consideration in the areas of port density, access layer uplink bandwidth, true server capacity, and oversubscription, to name just a few. This type of design supports many web service architectures, such as those based on Microsoft .NET or Java 2 Enterprise Edition. •L3 plus L4 hashing algorithms—Distributed Cisco Express Forwarding-based load balancing permits ECMP hashing algorithms based on Layer 3 IP source-destination plus Layer 4 source-destination port, allowing a highly granular level of load distribution. The load balancer distributes requests from your users to the cluster nodes. Server-to-server multi-tier traffic flows through the aggregation layer and can use services, such as firewall and server load balancing, to optimize and secure applications. Therefore the logical flow is determined by the current data status in data store. Data center architecture is the physical and logical layout of the resources and equipment within a data center facility. It’s a 1 year Technical Diploma program on Data Center Architecture. For example, the database in the example sends traffic directly to the firewall. Data centers are growing at a rapid pace, not in size but also design complexity. The core layer runs an interior routing protocol, such as OSPF or EIGRP, and load balances traffic between the campus core and aggregation layers using Cisco Express Forwarding-based hashing algorithms. •HPC Type 3—Parallel file processing (also known as loosely coupled). –Applications run on all compute nodes simultaneously in parallel. 2. –The source data file is divided up and distributed across the compute pool for manipulation in parallel. It is a layered process which provides architectural guidelines in data center development. Data Center Architects are also responsible for the physical and logistical layout of the resources and equipment within a data center facility. •HPC type 2—Distributed I/O processing (for example, search engines). The client sends a request to the system to perform actions (e.g. The majority of interconnect technologies used today are based on Fast Ethernet and Gigabit Ethernet, but a growing number of specialty interconnects exist, for example including Infiniband and Myrinet. A central datastructure or data store or data repository, which is responsible for providing permanent data storage. A Data Center Architect reported making $115,014 per year. Intel RSD is an implementation specification enabling interoperability across hardware and software vendors. Intel RSD defines key aspects of a logical architecture to implement CDI. The remainder of this chapter and the information in Chapter 3 "Server Cluster Designs with Ethernet" focus on large cluster designs that use Ethernet as the interconnect technology. Company - Public. Job Highlights. –Can be a large or small cluster, broken down into hives (for example, 1000 servers over 20 hives) with IPC communication between compute nodes/hives. Although high performance clusters (HPCs) come in various types and sizes, the following categorizes three main types that exist in the enterprise environment: •HPC type 1—Parallel message passing (also known as tightly coupled). VerifythateachendsystemresolvesthevirtualgatewayMACaddressforasubnet usingthegatewayIRBaddressonthecentralgateways(spinedevices). meta-structure of the Web) and follows hypermedia data model and processes communicate through the use of shared web-based data services.
