This storage technology is also a cost-effective and efficient way to provide data security, and most server manufacturers offer it as an option. RAID combines two or more hard drives into one logical drive or array so that data may be saved on all of them. Advanced midrange and enterprise servers usually come with hardware RAID controllers. Uninterruptible power supplies come as an option with most servers and protect them from power spikes, brownouts and outages that can result in data loss. UPSes compensate for power fluctuations and, in cases of outages, give you time to shut down your servers before they are damaged or lose data.
Most organizations require daily backup of the data stored on a server s hard drives.
A tape drive system should contain a larger capacity than the total combined sizes of the hard drives in the server. Network interface cards. NICs, also known as network adapters, are small circuit boards installed in your servers and client devices. Redundant server components provide some guarantee against total system failure in case one or more subsystems fail. Hot-swap SCSI hard drives can be replaced without powering down the entire system.
