8tb raid storage

In recent years, customers have always asked original storage engineers about the storage RAID plan (RAID, 5, 6 ....): "How many RAID are used? What RAID level is used? Why is RAID at t

data storage requirements, it is unthinkable. Because of this, a new technology--raid was born.Redundant array of independent hard disks (RAID, redundant array of independent Disks), formerly redundant Array of inexpensive disks (redundant array of inexpensive Disks), referred to as hard disk array.The basic idea is to combine a number of relatively inexpensive

different hard disks, and the Ribbon units arebits or bytes, using what is called a sea-plaintext to provideerror checking and recovery。 This coding technique requires multiple disk storage checks and recovery information, making RAID 2 technology more complex to implement and therefore rarely used in a business environment.RAID3parity (XOR) stripeStorage, shared check disk, data stripe

magnitude.2. IOPS calculation for raidWith the ioPS of a single disk, the IOPS calculation for multiple disks is simple, for example, for storage of RAID0 or simple tandem disks (Jbod:just a bunch of disks), the total IOPS of 10 175 ioPS is 10*175 = 1750 IOPS.However, for other RAID levels this is not the case, because the raid has multiple write IO overhead, si

Currently, there are many disk storage products, generally using high-performance fiber channel connections, Such as IBM storage products: http://www-900.ibm.com/storage/cn/disk/ HP Storage products: http://h20427.www2.hp.com/products/storage/cn/zh/enterprisestorage.asp

When a cloud project is delivered, it is inevitable to consider what raid the storage disk will take. For example: Our project engineer may recommend that you connect a clone virtual machine system disk Group RAID 10, complete replication virtual machine data diskUsing RAID5 or RAID6 and so on, what exactly is RAID?
