Only decades ago, computers were so massive that they filled entire rooms and took multiple people to operate. Now, we carry highly advanced computers in our pockets and wear them on our wrists. Technology is always changing, and it’s never going to stop.  As technology advances, it evolves to fulfill different functions and needs. Dell server generations renew every three to four years. With each generation, the chassis frame stays the same, but the servers are updated with faster processors and better expansion cards. Different models of Dell servers are used for different things; there’s no “one size fits all” server. ​There are five main types of Dell servers: ​• C = Cloud: Modular server nodes for hyper-scale environments  • F = Flexibility: Hybrid rack-based sleds for rack-based...

Serial ATA (SATA):  These are the basic hard drives in Dell PowerEdge servers. These have a few advantages over the older parallel ATA, including reduced cable size and cost, native hot-swapping, and faster, more efficient data transfer. SATAs are the cheapest drives, but their MTBF (mean time between failures) isn’t great. Most of the time SATAs fail on basic Dell server systems. Near Line SAS:  These are enterprise SATA drives with an SAS interface, head, and media, and the rotational speed of traditional enterprise-class SATA drives with the fully capable SAS interface typical for classic SAS drives. Near Line SAS drives provide better performance and reliability than SATA drives. Basically, this drive is a hybrid between SATA drives and SAS drives....
