[Data recovery failure description] A Dell PowerVault NF500, 3 300G SAS hard Drive composed of the RAID5 logical volume, the operating system for WSS 2003, two hard drive offline led to the entire NAS system is not working, Dell engineers forced the data after the failure to recover successfully. The original logical volume is divided into C, d two areas, C for the system partition, you can reload, D is the data area, just export. [Data Recovery an

In fact, the Indy control in Delphi comes with MD2,MD4,MD5 objects, and we can use them directly to complete the MD5 signature algorithm. Instead of having to find other DLLs or pas. It is possible to achieve MD5 by referencing the

the needs of high-end users to build large data resource centers. In terms of networked storage, PowerVault recently launched a new NX1950 network add-on storage product. This storage device integrates the simplicity of NAS (network-attached storage) with the high-availability of the San (storage local area network), integrating a number of technologies such as Fibre Channel and iSCSI, and can store both file data and application modules in virtually

Windows Storage Server 2003 works with major OEM/ODM manufacturers. Based on Windows Storage Server 2003, five storage solutions were launched to meet enterprises' requirements for different storage solutions, such as disk arrays, servers, and heterogeneous network environments. Windows Storage Server 2003 only provides network storage products integrated with hardware and software by means of OEM vendors that Microsoft cooperates with. It does not sell independent software CDs for independent i

Disk Management -- Raid1 + 0 volume + LVMPreparations Take two disks as an example: SDB and SDC. Three primary partitions are created for each hard disk. Sdb1 1g, sdb2 1g, sdb3 1g Sdc1 1g, sdc2 1g, sdc3 1g Step 1: Create sdb1, sdc1, sdb2, sdc2, sdb3, and sdc3 as raid1, md1, md2, and md3 respectively. Step 2: Create md1, md2, and md3 as raid0 volume md0 Step 3: Use LVM volume management to create the raid0 v

First, briefMD5 algorithm is a typical message digest algorithm, its predecessor is MD2, MD3 and MD4 algorithm, which is improved by MD4, MD3 and MD2 algorithm. Whichever MD algorithm, they all need to get a random length of information and generate a 123-bit message digest. If this 128-bit binary summary information is converted to 16, you can get a 32-bit string, so the majority of the MD5 algorithm we se

Encryption during network transmission to prevent interception and data modification (Anti-cheating) 3. Game Data Encryption (Anti-cheating) Ii. encryption: prevents piracy and cheating. Iii.
