server to the passive node, making it the active node. If neither of these approaches is feasible, additional I/O throughput should be designed in the architecture, providing a rebuild condition for RAID 5 or RAID 6 during working hours. This additional I/O throughput can reach twice times the I/O throughput in a non-faulted state.If your backup solution (VTL or D2D) needs to maintain a certain amount of data throughput, you have to consider how many

Work: A virtual tape library (VTL) has the same components as that of a physical tape library doesn't that the majority of the components are presented as virtual resources. for backup software, there is no difference between a physical tape library and a virtual tape library. Virtual tape libraries use disks as backup media. emulation software has a database with a list of virtual tapes, and each virtual tape is assigned a portion of a lun on

Vendors that use in-band encryption devices include brocade switches, Cisco Systems's MDS storage media encryption and NetApp's DataFort. Media encryption technology uses multiple technologies to encrypt data in specific media formats. These technologies may integrate storage arrays to encrypt each drive in the array. More typical is tape encryption, a media backup server, tape library,

Reset support is not good, there is no unified implementation, both the implementation of the sun, and the implementation of Apache-myfaces, write a custom component requirements high, more suitable for enterprise applications.

Sometimes we need to display the serial number in the page, and the program object does not contain the same ordinal attribute, it can be defined by itself.

efficient use of electricity. Fewer physical servers or physical storage means less energy requirements. But technologies such as virtualization and duplicate data deletion do not exist out of thin air. To effectively improve disk to disk energy efficiency, you need to check the energy consumption of each product category and how to improve its efficiency. The various comparison data used below are based on the public energy consumption specifications of each vendor. Although the deployment o

(Translator Note: An asymmetric encryption algorithm requires two keys: Public key (PublicKey) and private key (Privatekey). Public key is a pair of private key, if the data is encrypted with public key, only the corresponding private key can be decrypted, if the data is encrypted with private key, then only the corresponding public key can be decrypted. Because encryption and decryption use two different
