Data Center

QuestionAnswer
What does the data center house? It houses a collection of key IT assets that are critical to the operation of the company
What is the main role of the Data Center? To house, manage, and facilitate the gathering, processing, and distribution of corporate information.
What role does IT have in relation to business processes? IT helps streamline business processes.
Why should we strive to streamline business processes? To achieve productivity gains.
How can the data center help reduce operational overhead? By centralizing and sharing equipment and resources.
What are components of a data center? physical facilities, protected server rooms, cabling infrastructure, power and cooling, and security systems; servers; network facilities; storage devices and networks; software such as business applications and management applications.
What drives the technologies, the policies, and the evolution of the data center? Business Needs, Business processes and information resources.
What are some Data Center operational pain points? unanticipated downtime, network congestion/outages, resource shortages, disruptive upgrades.
What are some key functions in data center design? selecting vendors, developing architectures, setting standards, and exploring new technologies
What are IT departments constantly balancing? IT is constantly balancing its resources, such as capital, operational budget, and headcounts, against its activities such as meeting deadlines, meeting business needs, and aligning technology with business goals and issues.
What are three commonly recognized top-level business drivers for data centers? They are to protect the business from information outages, to optimize the efficiency with which IT operates, and to grow IT systems.
Protecting the data center mean? Protecting the data center means constantly improving business resilience and the ability of the business to continue in the face of unplanned events and ensuring that the data is secure.
What does Optimizing the data center mean? Optimizing means increased operational efficiency through focusing on using capital expenditure to minimize longer term operational expenditure, which is by far the greater fiscal burden on data center budgets.
What is needed to allow a data center to grow? Having a roadmap and plan along with the appropriate architecture and technology that allows for flexibility and adaption in regards to adding new applicaitons and services into the data center.
What is mean by a Siloing approach and why is it not a good approach? Siloing is an approach where a set of data center resources, such as servers and storage, is committed to a single application. This typically leads to poor utilization of data center resources.
What are two types of costs in the data center? Capital costs - upfront costs and Operational costs - costs to sustain the data center.
Are CapEx of OpEx a bigger financial burden? OpEx is often the bigger burden over the lifetime of the solution. CapEx, although high initially, decreases over time. OpEx tends to be initially high to cover the deployment, and then it drops back, only to rise again over time as solutions age.
Why can reducing even small area's of OpEx be a big cost savings? OpEx accumulates over time, so relatively small OpEx savings often translate into a significant reduction in total cost of ownership.
Does CapEx of OpEx follow the economy? CapEx typically follows the economy, whereas OpEx is consistent. IT organizations who are aware of this fact will want to invest in solutions that promise to reduce OpEx over time.
What are the four phases to approach next generation data centers? Consolidate data center resources, virtualize resources, Integrate resources, automate.
What does server and storage consolidation in the data center produce? Increased scalability, density and availability of resources. Immediate improvement in resource utilization and manageability.
What is a big advantages of virtuatlized resources? Virtualization saves on DC real-estate, saves power on power, saves on hardware, reduces OpEx costs as their is hardware to manage.
What encompasses integrated resources in the data center? Providing Unified Network Fabric, and using the network as an intelligent platform for integrated services like load balancing, ssl offload, security.
What types of applicaitons work well with NAS? File serving, File sharing Users'home directories, Content archiving, Metadata directories E-mail repositories, such as enterprise .PST files, Peer-to-peer data sharing
What types of applications work well with SAN? Databases, Server clustering, Messaging applications, Backup, Data replication, GRID computing Data warehousing, Recovery archives, Any application that requires low latency and high bandwidth for data movement.
What does virtualization mean? The method of pooling physcial resources together and then providing a logical OS, logical SAN, logical Switch etc.. Logically segmenting the service within pooled devices as opposed to physically segmenting.
Why is multiprotocol support needed in the data center infrastructure? high-performance compute cluster might require InfiniBand; a data-intensive grid application might require 10 Gigabit Ethernet a heterogeneous SAN might require Fibre Channel, Fiber Channel over Ethernet (FCoE), IBM Fiber Connection (FICON), ISCI
What does Heterogeneous mean? Heterogeneous is a mixture of 2 or more elements.
What is the purpose of the core layer? Core Layer – provides the high speed packet-switching backplane for all flows going in and out of the data center and to and from aggregation modules.
What is the purpose of the aggregation layer in the data center? aggregating the thousands of sessions leaving and entering the data center. must be capable of supporting many 10 GigE and GigE interconnects while providing a high-speed switching fabric with a high forwarding rate.
What is the purpose of the access layer? Access Layer The server and storage access layer is how servers and storage devices gain access to resources such as SANs, InfiniBand switches, and the IP Network.
What are some data center design considerations? Sufficient port density for current and future growth Access layer uplink bandwidth Server capacity Acceptable oversubscription
What should the data center design hope to achieve? scalability, flexibility, performance and resiliency in mind
