reliability defect, RAID 0 is the most cost-effective and high-performance option for block-level strip across all Disks without verification or mirroring, however, a single disk failure will lead to the loss of data in the entire RAID group, making it difficult to log on to the data center. On the other hand, RAID 1 image, unverified or strip) and RAID 10 strip disk image), combined with high performance

cost of ownership and protecting the user's investment.The NAS itself can support a variety of protocols (such as NFS, CIFS, FTP, HTTP, etc.) and can support various operating systems. NAS is a truly plug-and-play product with a flexible physical location that can be placed in a workgroup or in a hybrid environment, such as a hybrid unix/windows LAN environment without any modifications to the network environment. NAS products are directly connected

Use iSCSI Target to create centralized security storage (1) ISCSI is a block-level protocol used to share original storage devices through TCP/IP networks, you can use an existing IP address and ethernet address, such as a nic, vswitch, or vro, to share and access storage through the iSCSI protocol. ISCSI target is a r

position; 4. Analyze the stored data and query statements to clarify the query output results so that frequently accessed data can be evenly distributed across multiple disks. The goal of the multipart storage design is to provide users with better response time, better concurrency, better and faster backup and recovery, and better availability. However, the management cost of the database is virtually inc

, many small and medium enterprises prefer to use iSCSI storage for cost effectiveness.It is very important to distinguish between SCSI devices and FC Optical Fiber devices. FC Optical Fiber devices simulate the abstract devices of one or more SCSI devices at the bottom layer of storage virtualization, and do not have real SCSI devices, it is simulated through th

Next: Architecture Design: System Storage (4)-Block storage scheme (4)1. mysql OverviewFrom the beginning of this paper, we will discuss the performance optimization scheme and cluster scheme of the relational database based on the block storage scheme. The selection of a relational database will target the most widely
