![]() A virtual data center requires less equipment, less power, and less room than a traditional physical data center. With data center virtualization, administrators can create a virtual data center infrastructure using remote servers to share the workload and storage. ![]() Now, servers can be virtualized, where processing power and memory are separated from the hardware in a virtual machine. Physical data centers are limited by space and their reliance on hardware and equipment. Archived data can live in the lowest and least expensive storage tier, where high latency is less of an issue. Lower performing storage tiers can act as back-up for the primary tier, or as storage for data that is less frequently accessed. Businesses such as financial services or medical research that use high-performance computing for big data analytics are frequent users of Tier Zero storage. The tier with the lowest latency and the fastest access typically lives closest to the users, where users can easily interact with it on a daily basis. In public cloud-based storage-as-a-service models, tiers with low latency are generally more expensive than tiers with higher latency. Tiered data centers allow for hierarchical data storage, where the files and data for applications that users access most frequently, or that require very high performance, can live in one tier, while data that is not accessed as frequently can live in a different tier. Network and application security software can provide essential virtual security measures.ĭata centers can have different levels of security, latency, and resiliency-these levels are known as tiers. A data center must be protected from theft with physical security measures such as locks, video surveillance, and restricted access. Both physical and virtual security measures are necessary to ensure that a data center stays secure and that businesses are not vulnerable to a data breach. A breach where sensitive customer or company data becomes exposed can cost hundreds of thousands of dollars and, in worst-case scenarios, destroy a company’s brand and business. Physical and virtual security measures: Security is an important aspect of any data center because of the business-critical applications and information it contains.Instead, data centers can use chemical fire-retardant systems that smother flames without harming electronic equipment. Water can destroy computers, so sprinklers cannot be used to protect the equipment in a data center from fire. Cool conditions: All of the power and equipment in a data center generate a lot of heat, so data centers often require some kind of cooling equipment to operate optimally.Virtualized or software-defined data centers are more efficient and require much less power than traditional data centers. Abundant, reliable power: The equipment in a data center often requires a large amount of power, from a source that is immune to interruptions through immediately available back-up power.Because data centers contain so much expensive IT equipment, they have special requirements for security and power.
