from processor speed to memory. Knowing your next server purchase details can make you a knowledgeable buyer and help determine the most important features of your organization. This topic is discussed in "Understanding Server Selection: How to Evaluate Your Business Needs." However, when you make a purchase, knowing how to differentiate what you want and what you need can help you focus on server requirements and even make room for some extra features.
Is there any space left in your cabinet or rack to place additional servers? If you have a blade system, do you still have space to add a blade? The remaining space in the cabinet and on the rack, or even any available floor (even if the physical package is removed) will affect the type of server you should consider.
For example: If you do not have the available floor space, but also in the cabinet on rack space, you may have to be forced to choose for those servers or restrictions. On the other hand, if part of the role of the new server is to integrate the old system and plan to make more room in the future, you still need temporary space during the transfer and upgrade.
physics-based, equipment and environmental considerations (consideration: the technical environment), including power, cooling and heating, ventilation and air conditioning systems, which will affect your server needs. Always consider where the main source of electricity you can use, where your uninterrupted backup power supply and generators are. Even if there is enough floor space, rack or cabinet space, there may be restrictions on power and cooling capacity. Speaking
supply, power is king. Many energy companies offer incentives, discounts and other means to encourage efforts in energy conservation and energy conservation. While some incentives are based on a comprehensive reduction in energy consumption through consolidation or upgrades, other rewards will reduce or maintain energy during the business growth period (do more with the resources you have).
choose to buy energy-efficient servers and similar appliances, you can select those with the Energy Star qualified servers or energy. These servers typically have advanced smart energy management capabilities and more than 80% energy savings. Organize a list of available solutions from your local energy and solution providers. But to get started early, some projects must be started before starting all upgrades.
Do you need a SAN or NAS?
Although the use of storage area networks and network-attached storage networking and shared storage has become a trend, but there are still many server built-in disk drive. For applications or environments that specify internal storage, there are many options for performance and capacity, most of which are migrations to physically smaller and more energy-efficient 2.5-inch SAS devices. Many servers are also equipped with (or provide options for) PCIe SAS RAID adapters to improve the performance of internal and external storage.
Understanding Server Performance: Metrics and Comparisons
Server performance comparisons can be quite different, even in the best case, it’s a bit like taking apples and oranges. Comparison. With this in mind, when evaluating servers, consider performance with lower power-up mode and energy and cooling server requirements, taking into account both normal and heavy load conditions.
Other factors that can be used to determine server performance in all metrics are: CPU processor utilization percentage, response time, number of transactions, information, computational operations, I/O operations, files per second or Video service capabilities and the number of megahertz or gigahertz. However, effective performance should be measured by how well all components work together under different load and operating conditions.
There are many different tools for similar workloads and benchmarks (including Iometer and Microsoft's ESR, and standard performance and evaluation companies, those of the Transaction Performance Committee), but the best testing and comparison tools Is the closest environment to the application or load that the server will support.
you need and what you want
understand your needs and the needs of the server is divided into three categories: what you need, what you want and have the most Ok. They sound similar, but it guarantees that your basic server needs are met and won't be changed by others who are trying to sell you more advanced or optional features in the procurement process.
Summary: Be an informed buyer and do your own research. Understanding server requirements and all the optional servers and available features will ensure that you can meet both business and IT needs.
