data disk of transaction systems is mainly caused by dirty Data Writing (maybe your situation is different from mine). Generally, IOPS is not high. This depends on the system. If IOPS is not enough, you can consider using SSD to increase IOPS, but the storage does not support SSD well. It is best to scatter ssd io in multiple storage fiber loops. 3) ORACLE's group commit is an automatic and default action. In fact, it cannot be optimized without optimization. 4) set the CACHE attribute for key

The Hyper-V virtual Fibre Channel feature for virtual machines enables virtual machines to access Fibre Channel-based storage devices. This feature enables enterprises to virtualize workloads that require Fibre Channel usage, and enables enterprises to create clusters using Fibre Channel with guest operating systems running in virtual machines.The Virtual Fibre Channel adapter provides port virtualization capabilities by providing a host bus adapter (HBA) port to the guest operating system. This

IP San is easy to realize remote data access. However, the efficiency, performance, and security of the IP San are its short planks relative to the FC San.2. The technical principle of FC and IPFibre Channel layered According to the protocol layer, each layer of technology is independent of each other, leaving room for growth, and by the approved standardization

High intelligence, high availability, and high reliability are the characteristics of multi-layer intelligent optical fiber switch. Although its technology is not very mature yet, it has been recognized by people. Cisco Systems recently announced that it will launch the CiscoMDS9100 series of multi-layer smart Optical Fiber switches this fall to meet the needs of small and medium-sized enterprises for deploying storage networks (SAN) based on cost con

Hyper-v Server Virtual Fiber ChannelThe new virtual Fiber Channel (VFC) in Windows Server 2012/R2 enables Hyper-vclient to access the physical storage host bus adapter (HBA) installed on the Hyper-V Server ). Generally, Hyper-VPC is equipped with storage adapters. However, with the help of this new feature, all Hyper-V 3.0/4.0 clients with the corresponding O/S level can access the HBA and directly connect to the optical fiber path storage device. The realization of the virtual fiber channel fun

Welcome to the network technology community forum, and interact with 2 million technical staff to back up SAN settings to the hard disk, rather than SAN.

In the storage device is the most important should be hard disk, the drive to read and write speed, capacity and quality of the pursuit of hard disk technology has undergone several changes. From the interface standard of the motherboard with the ATA (IDE), SATA, SCSI, SAS, FC and InfiniBand, they have a certain difference in interfac

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 to the network via a network interface, which
