Performance Servers are more likely to  perform multiple tasks simultaneously  than an individual PC. That's why Dell PowerEdge servers are maximised for performance with  fast data transfer through more processing  power and memory than are generally available on PCs. Scalability As your network grows, so can your Dell server. You  can add much more memory and hard disk capacity  to a Dell server than to a PC. And if you need additional processing capacity over time, you  can add processors as needed. Reliability If a server goes down, it can  dramatically impact your productivity and your bottom line . Servers offer a variety of reliability features like redundant power supplies and fans that help keep your business up and running when a desktop PC would have failed. Your specific needs for performance, scalability, and reliability determine which server platform you should buy and how you should customise it.

Share files with each other Systematically back up data on a regular basis Share peripherals such as printers. Communicate via email Access the Internet simultaneously

Networks provide a link between people, information, and devices. They allow users to share resources such as data, applications, and peripherals easily and efficiently. Networks make it easy for your employees to:

Scene 6

What Applications Will Run on Your Server?

The performance requirements of your server depends on the type of application you plan to run on it. Following is a range of functions that servers can support:

File/Print Sharing Server E-mail Server Applications Server Databases Server Multi-tasking Server Web Server Backup Server. End point security. Accounting Server HR Application server Domain Controller & Backup Domain Controller

Scene 7

RAID, which stands for Redundant Array of Independent Disks, is a technology that was developed about 10 years ago to improve performance and availability while storing large amounts of data without requiring improvements in disk drive technology. It comes in several levels for a variety of ways to store data.

Scene 8

RAID 0 Also known as data striping, RAID 0 writes data in sequential stripes across more than two drives. RAID 0 has no data redundancy, so it does not protect against data loss; however, it can dramatically improve performance because it can access several drives at once, minimising the overall seek time of larger files. The simple design of RAID 0 is easy to implement, though it should not be used for business-critical applications

Scene 9

RAID 1 RAID 1, or drive mirroring, works by simultaneously copying data to a second drive. This mirroring technology offers excellent data protection and delivers good performance if a mirrored drive fails. RAID 1 is the simplest RAID design. It requires a minimum of two drives with equal capacity, and the drives must be added in pairs. The main disadvantage of RAID 1 is its 100 percent disk overhead (highest of all RAID levels), which results in inefficient use of drive capacity.

Scene 10

RAID 5 With RAID 5, each entire data block is written on a data disk and parity information is striped across all drives. RAID 5 is the most popular of RAID levels because it delivers data protection and good performance with a small overhead for parity. RAID 5 offers the most efficient use of drive capacity of all the redundant RAID levels. It needs at least three drives of equal size, which can be added one at a time. RAID 5 has a high read transaction rate and a medium-to-high write transaction rate with a good aggregate transfer rate.

Scene 11

RAID 10 RAID 10 combines RAID 0 and RAID 1 by striping data across multiple drives without parity and it mirrors the entire array to a second set of drives. This process delivers good performance and excellent data protection, but cuts the usable disk space in half. RAID 10 requires a minimum of four same-size drives, and is also the most expensive RAID solution and offers limited scalability.

Scene 12

Here, we’ll look at the use cases, strengths, and weaknesses of each of these three storage systems to help you choose the one that best suits your business requirements.

Three primary options for enterprise data storage systems are Direct-attached storage (DAS),  Network-attached storage (NAS),  Storage area networks (SANs).  Each offers advantages and disadvantages for organizations.
