What are some tips on building a raid array?
A RAID (Redundant Array of Inexpensive Disks) array requires two identical drives, preferably of the same brand, model, and capacity. A few SATA cables are also necessary for building a RAID array. Both drives then need to be installed, as well as connected by SATA cables.
Is A group of hard drives implementing RAID called an array?
RAID stands for a redundant array of independent disks. Thus, a group of two or more hard disks comprise a RAID, or array of physically separate drives.
What is a group of hard drive implementing RAID called?
A group of hard drives assembled into a RAID array is often referred to as, well, a "RAID array" a "RAID stack" or a "RAID cluster."
Installing a hardware RAID for best performance?
All hard drives in an array should be identical in brand, size, speed, and other features. Also, if Windows is to be installed on a hard drive that is part of a RAID array, RAID must be implented before windoes is installed. As with installing any hardware, read the documentation that comes with the motherboard or RAID controller.
True or false a group of hard drives implementing RAID is called an array?
False
Which problem is addressed by RAID technologies?
A RAID array is an array of several hard drives all sharinf parts of the information you save and use. So if one hard drive dies you don't loose all your information. It's easy to recover your data using the other RAID drives.
What are two possible remedies for a disk subsystem that is the bottleneck in a servers performance?
ANSWER Any two of the following: ■ Install faster hard disk drives. ■ Install additional hard disk drives and split your data among them, reducing the I/O burden on each drive. ■ Replace standalone drives with a RAID (redundant array of independent disks) array. ■ Add more disk drives to an existing RAID array.
Why would people utilize RAID 1 so costly?
It's true that whenever you use RAID you create an additional point of fault, but because RAID 1 (mirroring) allows identical content to be repopulated on its member drives, it provides a form of redundancy (which is what was intended [RAID = redundant array of inexpensive disks / independent disks]). However, as most people would say, RAID is not a substitute for a backup, so it's good to have a back up in case if your RAID array fails.
What describes a group of two or more disk drives that appear to the system as a single drive?
Raid Array.
What does raid stand for?
"Redundant Array of Independent Disks"or you can also say"Redundant Array of Inexpensive Disks"RAID means you have your computers Hard drives linked to work in sync with each other,this could be used to back up data instantly or used to make your Hard drives all work as one big storage device.If you had two 500GB drives and put them in RAID you could make them act as one 1TB drive,the data would be split between the two drives.Redunant Array of Independant Disks.
What is the role of a disk array RAID controller?
It's a device that manages the physical hard drives installed into you computer. Since it's very common when used in hardware RAID, it is often called a RAID controller.
How many disk are damaged if system of RAID 5 with 4 disk is crashed?
Sorry, but I disagree with Rtrahan once again. His answer doesn't even appear to apply to the question that is asked.It seems that what the RAID array is telling you is that Disk #4 has failed and needs to be replaced. If you mean to say that your RAID array failed on you completely (such as due to a power outage) and you are wondering which of the drives (if any) are physically damaged, then the only way to determine that is to get into the diagnostics of the RAID array itself. In the diagnostics, it should tell you if any of the drives are degraded or failed. If you have only one such drive, then you can replace it and the array will rebuild itself (which is what it is designed to do, of course). If you have two or more in a degraded state, then I hope you have a backup because all your data is toast unless you want to send the array off to a data recovery lab and pay big bucks to have it restored.RAID 5 arrays must have a minimum of three drives to be set up initially (but can be used with any number of drives that the computer or NAS or other RAID-compatible device can address). This is so that the data is striped across the drives and the equivalent of one drive is used for parity. Thus, in the case of a three-drive RAID 5, the amount of useful data storage is the equivalent of two drives. The same pattern continues as the number of drives increases: the capacity of the array is the total amount of storage of all but one of the drives. All drives in a RAID array must be the same size and ideally the same model.For greater fault tolerance, RAID 6 is sometimes used. In this case, there are the equivalent of two drives with parity. This allows for two drives to fail rather than just one. The disadvantage is that RAID 6 requires a minimum of four drives to be used but can expand to any supportable number of drives beyond that.If you have any questions or would like further assistance, feel free to drop me a line.
