What is RAID level 1 also called?
Disk mirroring
To provide redundancy you want to implement raid by mirroring the data and use the least number of hard disks which raid level will you implement?
RAID 1
What provides redundancy through a process called disk mirroring?
RAID level 1
Disk mirroring involves creating a shadow copy of data on a backup disk and is RAID level?
Level 1
How important are raid levels?
The actual level used is not as important as what use the server is intended for. Different levels of RAID are used for different applications. They can include mirroring and striping.
How do you mirror 2 drives in a computer?
Raid 1 is mirroring.
What term is used to describe disk mirroring?
RAID 1. Redundant Array of Independent Disks.
Which RAID level mirrors one hard drive with a second drive so that the same data is written to both drives?
That is RAID 1. It uses two drives with identical data so if one fails, you have the other drive. One variation of RAID 1 used by certain controllers is to write as RAID 1 but read more like RAID 0 (but without the striping). That way, you have the write protection of a mirrored set, but can use the two drives to do interleaved reads for a read performance boost.
A company employee has very important data on a computer What RAID level should be used if the criteria include that data be written and read simultaneously and that all data be duplicated using a mi?
Mirroring is the method it is used. This is commonly in the specifications of RAID1, RAID5, RAID10, RAID1+0, RAID15, and others. RAID is commonly used to designate RAID (Redundant Array of Independant Disks) setups, but RAID is not technically recognized as a specification, and not all RAID types and enumerations (such as 15) are even recognized as valid designations. RAID may also not involve data redundancy or mirroring at all, such as in Striping (RAID0, RAID2, RAID3, RAID1+0, etc.)
What RAID implementation provides no fault tolerance?
RAID level 0RAID 0RAID 0 (block-level striping without parity or mirroring) has no (or zero) redundancy. It provides improved performance and additional storage but no fault tolerance. Any drive failure destroys the array, and the likelihood of failure increases with more drives in the array.
What are RAID 1 and RAID 5?
Raid 1 suppports the Mirroring if any one hard disk faild one will get the copy of the data and fault tolerent. after replacing the hard disk you have to re create the mirroring. Raid 5 supports stripped with parity the data will be deviced into blocks and stored in all the drives with the parity information. if any one or two hard disks faild the data will be available.
How many RAIDS are available for fault tolerance methods?
RAID (Redundant Array of Inexpensive Drives) is the technology developed to decrease risk involved with the usage of individual disks for Storage. RAID adds realibility & provides performance in Read methods. Well Known RAID Levels are 1. RAID0 - Striping, 2. RAID1-Mirroring, 3. RAID2 - Striping at Bit levelusing Errorcorrection code on disks, 4. RAID3 - BYTE Level striping with parity disk, 5. RAID4 -Block Level striping with Dedicatedparity disk, 6. RAID5 - Striping at Block level with Distributed Parity, 7. RAID6 - Block level striping with Dual Distributed Parity.All RAID levelsenable Fault Tolerant storage volumes except RAID0.
