Raid 10 chunksize

"Raid 10 chunksize I'm trying to pin down some performance issues with a machine where I work, we are seeing (read only) query response times blow out by an order of magnitude or more at busy times. Initially we blamed autovacuum, but after a tweak of the cost_delay it is *not* the problem. Then I looked at checkpoints... and altho there was some correlation with them and the query response - I'm thinking that the raid chunksize may well be the issue. . Fortunately there is an identical DR box, so I could do a little testing. Details follow: .

RAID 1+0 is the Cadillac of RAID | Storage Bits | ZDNet.com

"What is RAID 1+0? Sometimes shortened to RAID 10, RAID 1+0 is a particular combination of two different RAID levels: mirroring (RAID 1) and striping (RAID 0). The appeal of RAID 1+0 is simple: mirroring gives you the highest level of availability RAID offers, with the fastest rebuild times when a disk fails; while striping - using the proper chunk size - is the basis for high-performance I/O. . Put the two together and you have the best of both worlds. Until George showed up with his facts. . What about the poor performance George found? We re coming to that, but first a word from our sponsor. . There is an important difference between RAID 1+0 and RAID 0+1 that not everyone appreciates. In RAI" [3]

"RAID 10 or 1+0 . RAID 10 is effectively a similar version to RAID 0+1. Rather than striping data between the disk sets and then mirroring them, the first two drives in the set are a mirrored together. The second two drives form another set of disks that is are mirror of one another but store striped data with the first pair. This is a form of nested RAID setup. Drives 1 and 2 are a RAID 1 mirror and drives 3 and 4 are also a mirror. These two sets are then setup as stripped array. . Below is an example of how data is written in a RAID 10 implementation.

Nested RAID levels - Wikipedia, the free encyclopedia

"A RAID 0+1 (also called RAID 01, not to be confused with RAID 10), is a RAID level used for both replicating and sharing data among disks.The minimum amount of disks required to implement this level of RAID is 4. The difference between RAID 0+1 and RAID 1+0 is the location of each RAID system — RAID 0+1 is a mirror of stripes. The size of a RAID 0+1 array can be calculated as follows where is the capacity of the smallest drive in the array: . Consider an example of RAID 0+1: six 120 GB drives need to be set up on a RAID 0+1. Below is an example where two 360 GB level 0 arrays are mirrored, creating 360 GB of total storage space: Note: A1, A2, et cetera each represent one data block; each column represents one disk. .

RAID - Wikipedia, the free encyclopedia

"For example, RAID 10 (or RAID 1+0) consists of several level 1 arrays of physical drives, each of which is one of the "drives" of a level 0 array striped over the level 1 arrays. It is not called RAID 01, to avoid confusion with RAID 1, or indeed, RAID 01. When the top array is a RAID 0 (such as in RAID 10 and RAID 50) most vendors omit the "+", though RAID 5+0 is clearer. RAID 0+1: striped sets in a mirrored set (minimum four disks; even number of disks) provides fault tolerance and improved performance but increases complexity. The key difference from RAID 1+0 is that RAID 0+1 creates a second striped set to mirror a primary striped set. The array continues to operate with one or more drives failed in the same mirr" [9]

Disk 2 will be mirrored to disk 9 etc.If you don't care, then you can put all disk in, in any order, and power the server. You will get a warning, that places has been swapped, and you must press F1.I don't know if you can use the ADU afterwards to sort the original posistions.And I also don't know, if you can put 1 drive in, and use adu to retrieve the location of the missing drives.if you got an old adu, then you can find the location using the s/n.So if you don't care to keep the order, just put them in and power on the server.cheers/jag" [15]

RAID 10 vs. RAID 1: Mirrored drives matter

"While RAID 10 and RAID 1 are both mirroring technologies that utilise half of the available drives for data, there's one crucial difference: the number of drives that can be used in a RAID group. RAID 1 involves only two drives that are mirrored to provide resilience in the event of a single disk failure. RAID 10 involves at least four drives, and creates a RAID 0 stripe set involving two or more RAID 1 mirrors. . Depending on the location of the drives, a RAID 10 configuration can recover from multiple drive failures while using the same percentage of data drives as RAID 1. It can also provide increased performance due to the increased number of spindles in the RAID group." [27]

Exchange Server 2007 - Partioning RAID 10 - LUNS - Confusion - mine

"The RAID 10 array would present the entire space from an array.   If we set up six drives in RAID 10 (3 for the data, 3 for the mirroring) we would need to use Windows Server 2008 (which we own for this machine) to partition the space to present it for the storage groups for Exchange. EHLO and elsewhere seems to advise letting the hardware (or NAS; which we do not own) partition the space. Is it silly to consider using Server 2008 to partition a RAID 10 array or should I stick with RAID 5 and let the RAID card set up virtual disks? own RAID 1 array?

Earlier this month, a company came along and asked for a RAID 10 array. Understanding that RAID 10 is a cooler sounding way of saying RAID 1+0, I understood it as a mirror set that is striped across another mirror set. Simple enough Just concatenate a couple of mirrors, and you ve got RAID 10. . Indeed, RAID 10 is simply one or more RAID 1 arrays (mirrored sets) striped together (RAID 0). . RAID 1 creates an exact copy (or mirror) of all of data on two or more disks, while RAID 0 splits data evenly across two or more disks with no parity inf" [31]

Storage: RAID-DP vs RAID 10 protection

"Most vendors to date, use a RAID 1 or RAID 10 protection schemes to address the shortcomings of PATA/SATA drives. What we do know about these drives is that they have low MTBFs and the Bit Error Rate is 10^14. That's approximately 1 bit error per 11.3TB. Compare this to FC drives at 10^15 with 1 bit error per 113TB!!! . Drive reliability is a function of two elements: MTBF (Mean Time Between Failures) and BER (Bit Error Rate). Historically ATA drives have demonstrated lower reliability than SCSI or FC drives and this has nothing to do with the interface type but rather it's directly related to the components used (media, actuator, motor etc) in the drive."

What's RAID 10 And Why Should I Use It?

"What's RAID 10 And Why Should I Use It? . RAID is, of course, a Redundant Array of Independent (or Inexpensive) Disks. It is a method of storing information on multiple hard disks for greater protection and in some cases performance. Under the RAID umbrella are a number of different storage methods, called levels and numbered from 0 to 9, some of which are more useful than others. . Each level is a distinct method of organizing storage, but some of them can be combined which produces a two-digit RAID level, such as RAID 10, sometimes identified (and more appropriately so) as RAID 1+0."

Intel® Matrix Storage Manager - What is RAID 10?

"A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1 by forming a RAID 0 array from two RAID 1 arrays.Since all of the data on the RAID 0 array is duplicated, the capacity of a RAID 10 array is the size of the RAID 0 array. For example, four 400 GB hard drives in a RAID 10 array will appear as a single 800 GB hard drive to the operating system. . The primary benefit of RAID 10 is that it combines the benefits of RAID 0 performance and RAID 1 fault-tolerance. It provides good data reliability in the case of a single drive failure. When one hard drive fails, all data is immediately available from the other half of the mirror without any impact to the data integrity. In the case of a disk failure, the computer system will remain fully operational to ensure maximum p" [46]

RAID 10 Data Recovery, RAID 10 Failure

"RAID 10 (also called RAID 1+0) uses a minimum of four drives and additional drives must be added in even numbers. If four drives are used, a pair is first mirrored as in a RAID 1 and then striped as in RAID 0. The total storage capacity is calculated by summing the storage capacity of all the drives in the array and dividing it in half. This makes RAID 10 very expensive since it uses only half of the total capacity of all the drives. RAID 10 does offer increased performance over some of the other RAID levels due to the striping that takes place. Since mirroring occurs in RAID 10, the failure of one or more drives is tolerable as long as there is only one" [54]
