1When data availability is of great importance (i.e. in case a disk fails or data is lost and there is a
chance to recover it through a backup), the recommended form of storage is ________- ARAID 1: Disk Mirroring/Duplexing (Block-by-Block)
- BRAID 5: Disk Striping with Distributed Parity (Block-Level)
- CRAID 0+1/1+0/RAID 10: Striping and Mirroring Combined
- DRAID 6: Disk Striping with Dual Distributed Parity (Block-Level)
2A hard drive interface providing faster transfer times, thinner more flexible cabling, and
easier plug-and-play connections.- ANETWORK ATTACHED STORAGE (NAS)
- BSTORAGE AREA NETWORK (SAN)
- CSERIAL ADVANCED TECHNOLOGY ATTACHMENT (SATA)
- DREDUNDANT ARRAY OF INDEPENDENT DISKS (RAID)
3Offers striping (meaning data is “split” evenly across two or more disks) with no parity
or mirroring. The data is written to the physical hard disk block-by-block.- ARAID 1: Disk Mirroring/Duplexing (Block-by-Block)
- BRAID 0+1/1+0/RAID 10: Striping and Mirroring Combined
- CHardware RAID
- DRAID 0: Disk Striping (Block-by-Block)
4Relies on software to implement and control RAID techniques over virtually any type of hard
disk. It is less expensive overall than hardware RAID because it does not require a special
controller or disk array hardware.- ASoftware RAID
- BHardware RAID
- CRAID 6: Disk Striping with Dual Distributed Parity (Block-Level)
- DRAID 5: Disk Striping with Distributed Parity (Block-Level)
5Commonly used today to provide data storage that is not directly attached to the servers. They incorporate a pool of array storage drives accessed by, yet independent, of servers.
- ASERIAL ADVANCED TECHNOLOGY ATTACHMENT (SATA)
- BNETWORK ATTACHED STORAGE (NAS)
- CSTORAGE AREA NETWORK (SAN)
- DREDUNDANT ARRAY OF INDEPENDENT DISKS (RAID)
6Two parity blocks are written in this level to help in the data recovery process. It was used for preventing data loss in case of concurrent disk failures. Its advantages are the performance is high for read operations and it is good to use for large data transfers.
- ARAID 5: Disk Striping with Distributed Parity (Block-Level)
- BRAID 1: Disk Mirroring/Duplexing (Block-by-Block)
- CHardware RAID
- DRAID 6: Disk Striping with Dual Distributed Parity (Block-Level)
7Managed exclusively by the RAID disk controller attached to a server through the server’s controller interface. This will appear as another storage device to the operating system.
- AREDUNDANT ARRAY OF INDEPENDENT DISKS (RAID)
- BRAID 0: Disk Striping (Block-by-Block)
- CHardware RAID
- DSoftware RAID
8____ technology has been around for approximately 20 years and a number of factors have
come together to make it a reality for both large servers as well as desktop systems.- ASoftware RAID
- BSTORAGE AREA NETWORK (SAN)
- CNETWORK ATTACHED STORAGE (NAS)
- DREDUNDANT ARRAY OF INDEPENDENT DISKS (RAID)
9 Both data and parity information are striped across three or more drives. It is similar to RAID 4 except it exchanges the dedicated parity drive for a distributed parity algorithm; writing data and parity blocks across all the drives in the array.
- ARAID 5: Disk Striping with Distributed Parity (Block-Level)
- BRAID 6: Disk Striping with Dual Distributed Parity (Block-Level)
- CRAID 1: Disk Mirroring/Duplexing (Block-by-Block)
- DRAID 0+1/1+0/RAID 10: Striping and Mirroring Combined
10 Is a specialized high-speed network of storage devices and switches connected to servers
or computer systems. It presents a shared pool of storage devices to multiple servers.- ANETWORK ATTACHED STORAGE (NAS)
- BSTORAGE AREA NETWORK (SAN)
- CREDUNDANT ARRAY OF INDEPENDENT DISKS (RAID)
- DSERIAL ADVANCED TECHNOLOGY ATTACHMENT (SATA)
