VMware storage is not just as simple as mapping LUNs to physical servers. VMware vsphere allows system administrators to create multiple virtual machines on one physical machine. Potential hypervisor and vsphere ESXi enable the guest virtual machine to simultaneously use both internal and external storage devices. This article will discuss the basics of building sans on vsphere and what administrators consi

Nas and San are both competitive and cooperative, and many of the back-end storage of high-end Nas is SAN. The integration of NAS and SAN is also a trend for storage devices, such as EMC's new product VNX series . There are a lot of things that can be listed about the differ

With the increase in the time and data volume of enterprise network applications, enterprises have already felt that storage capacity and performance are lagging behind and network application development needs, especially for streaming media enterprises, the emergence of technical applications that meet users' storage needs under such conditions has led to the emergence of three

I. San data integration solution San data integration solutions increase asset utilization, reduce operating costs, and automatically allocate storage resources based on your business needs by pooling funds and manpower. -IBM San data integration solution If your enterprise is the same as most enterprises, branch

San mass Storage Solution With the advent of Fibre Channel technology and the development of network technology, the enterprise's deep understanding of centralized storage has gradually formed the concept of storage network. The storage network can realize data security

There are still many things worth learning about storage routers. Here we will mainly introduce the study notes of storage routers and SAN routers. The continuous development of enterprises will generate massive data, and these extended massive information must be stored and managed. In the process of storage, although

. Storage SolutionThe so-called storage solution is to use a separate software and hardware to manage the disk/disk group for use by the host.Currently, there are three plug-in storage solutions:(1) Direct Connected Storage (DAS: Direct Attached Storage)(2) Network

network extension applications have different transmission bandwidth requirements and quality of service requirements between storage networks. The following illustration shows their relationship. These transport bandwidth and quality of service requirements determine the required storage network expansion technology. The choice of storage network extensio

In this blog, I want to talk about the principles and implementations of SAN, do you still remember what the back-end storage technology is when I talk about HA and LB clusters in the previous section? NAS network attached storage ), of course, the efficiency of this technology is relatively low. If enterprises have high requirements on data

Introduction iSCSI (Internet SCSI) technology developed by IBM Research, is a hardware device used by the upper layer of the IP protocol can run the SCSI instruction set, which can be implemented on the IP network to run the SCSI protocol, Allows routing to be routed on such high-speed Gigabit Ethernet. iSCSI technology is a new storage technology that combines existing SCSI interfaces with Ethernet (Ethernet) technology to enable servers to Exchange

I talked to my friends about how to improve the performance of SQL Server and found some problems. For SQL Server, in addition to following the best practices of OS and applications, what are the optimization methods? Hardware-level optimization is also very important, especially storage optimization. After talking about this, we started to explain the SAN issue from the DBA's perspective. Many factors affe

bus adapters, Hba=, is actually the equivalent of a network card, but even the fiber optic cable.WWN:World Wide Name (WWN), similar to the MAC address of an IP network, has a unique WWN for each HBA.In a SAN environment, there are two types of WWN, WWNN (World Wide Node name) and WWPN (World Wide Port name). As the name implies, WWNN is typically for storage devices or

Connecting a host to a New SAN (storage LAN) is not just like connecting to a separate disk or even a directly connected SCSI Array. This article will explain the principles behind the current best connection method and how to set your storage to have the best stability. If you already use a direct-connected storage ar
