There is a growing number of people choosing an IDE disk array card (IDE RAID card) to ensure data security, and it is also a learning how to use the IDE RAID card correctly. Let's take a Rocket100 RAID card with ht370a/372 control chip as an example to explain common malfunctions and techniques. Installation need to know First find a free PCI slot to insert the card and the hard drive cable and the card

Disk Array Management of hpva7100 HP's 7100 disk array management software is used to manage HP's 7100 disk arrays. Its functions are mainly implemented by clui, fully called command line user interface. Install HP command view SDM on HP-UX 1. log on to the system as a Super

RAID5 is composed of at least 3 hard disks, each hard disk capacity, the data stored in the disk array of each hard disk, one of the hard disk storage data check bit, when the loss of one of them, RAID1 can through the algorithm, using other two-bit data to calculate the los

knowledge. I am afraid of knowing the problem when I start to learn materials and solve it. what impressed me most is: when the customer came to me, he told me that the server had already been RAID, but I was a bit blind. If I didn't know what this was, I simply understood it as READ, only by looking for such information can we know that RAID is the real thing. RAID is the abbreviation of Redundant Array of Independent Disks ).To put it simply, RAID

The Linux disk array is used to protect system data. Here we will start with the disk array, and then detail how to configure the Linux disk array on the Linux system. I believe that after reading this article, you will certainly

First, RAID overviewRAID is an abbreviation for the English Redundant array of independent disks, which translates into Chinese as "redundant array of independent disks" or simply as a disk array. To put it simply, RAID is a combination of several separate physical hard disks or partitions in a different way to form a

Array of Independent Disks ).To put it simply, RAID is an independent hard disk (physical hard disk: After observation, the blade server provided by the customer has four hot-swappable hard disks, each of which is 500 GB) A hard disk group (logical hard disk) is formed in d

data recovery requires data recovery engineers with extensive experience in data recoveryThe RAID array I received was comprised of 5 Hitachi SATA hard Drives, of which 3 were 36GB and the other 2 were 72GB, all using the Linux operating system and were initially identified as RAID 5 array types.The test found that one of the hard disk has a firmware problem, th

Traditional hard drives are very slow to improve performance because of the limitations of their working principles. But the solid state hard disk price is expensive, in a short time is difficult to accept by the ordinary user. Therefore, the use of two or more pieces of hard disk to build a RAID disk array has become

Nothing to do, group a RAID 0, feel good, the speed has been significantly improved, load the game and start the program speed improved Let's go ahead and compare the pictures.

How to spend a limited amount of money on a more cost-effective storage product is the most vexing problem for the small and medium-sized enterprises that are currently growing in storage demand. In the storage disk array, with the upcoming launch of the 6Gbps SAS standard, in the storage market this unique transition period, in the maturity of 3Gbps SAS related products, but gradually showed a trend of tre

RAID5 systems are typically used for data protection in many large business situations. It must be admitted, however, that the RAID5 disk array system only allows a single hard drive to fail, and as the number of disk capacity and array width increases, the likelihood of a drive potential flaw is close to 100%.

At present, the disk array technology is becoming more and more widely known. Disk array technology can be subdivided into several levels of 0-5 raid technology, and has developed the so-called RAID level 10, 30, 50 new levels. RAID is the abbreviation for a low-cost Redundant arra
