Discover network addressable storage, include the articles, news, trends, analysis and practical advice about network addressable storage on alibabacloud.com
Network virtualization is now a hot topic, and major manufacturers are scrambling to grab this cake. Technologies involved include virtual Emulation for NICs, I/O pass-through, SR-IOV), virtual access technology for networks VN-Tag/VEPA), covering network switching VXLAN/NVGRE ), and Software Defined network SDN/OpenFlow. For details, refer to the blog "
To improve network reliability and security requirements, we may want to separate the control and storage networks of openstack, that is, to configure the iscsi private network. Taking the kvm + lvm + iscsi ubuntu environment as an example, consider a simple deployment model, a computing node (nova-compute), a storage

Select a specific physical network card for the Ipstorage
One is to ensure bandwidth, no need and other applications to compete network resources. The second is to secure isolation. In addition to the VLAN, the proprietary physical network card further strengthens the isolation. If you are particula
the TCIP/IP protocol for communication. Therefore, you only need an Ethernet network to connect the two ends of iSCSI, the storage performance of iSCSI is directly related to this Ethernet, so it is best to use a Gigabit Ethernet switch in the iSCSI network. Poor network equipment will seriously affect the performance
RHEL7 disk partitioning, formatting, LVM management, and ISCSI network storage services, rhel7lvm
How to partition and format disks and how to configure LVM in RHEL7 is not much different from previous versions of RHEL. You can use disk tools (run on a graphic desktop) or command line tools (such: fdisk, gdisk, and parted) Manage hard disk devices. Fdisk can be configured with MBR format, gdisk can be confi
the sharing of tape libraries and disk array storage devices, the high availability of data, reducing the loss of downtime, greatly reducing operation and management costs, and improving asset utilization. In short, San is the most advanced storage infrastructure in the e-commerce field. IBM-leading San revolution No vendor can compare the contribution made in the Ne
Abstract: A video stream compression Solution Using Xvid for AVI file storage is proposed and implemented. The network video monitoring server uses Xvid to encode the collected video images, the storage system stores compressed video streams in the general AVI file format for retrieval and query.

We know that NFS is a network file system and plays an important role in network protocols. With the development of network storage. It has made great progress in this area. Here we will introduce the application of nas nfs in VMware. NAS is a simple network
multiple servers, after searching, calculation and analysis will be processed results back to the user. Through this technology, network service providers can process tens of millions or even billions of messages in a matter of seconds. Virtualization is a generalized term in the field of computers, which usually refers to computing components running on a virtual basis rather than on a real basis. Virtualization technology can expand the hardware ca
Nas, English is all called network attached storage, can be translated into network attached storage. It is defined as a special dedicated data storage server, embedded system software, which provides cross-platform file sharing capabilities. NAS devices completely data-cent
As a network management unit, it is no stranger to FTP and other self-built storage services, and cloud storage, which has recently been developing in full swing, cannot turn a blind eye to it. after some trial and understanding, I think it is time to say goodbye to the self-built LAN storage.Self-built LAN storage is
DBAs do not know the storage technology is the DBA is in vainThis network course, aims at in-depth discussion storage technology, the detailed explanation raid0, RAID1, RAID3, RAID5, the Raid6 and so on the characteristic, the emphasis compares the traditional storage technology and the Oracle all-in-one machine's
Yesterday, a linux system was deployed for a customer. The server itself had only GB disks as the system disk. All data is stored in network storage, and network storage (iSCSI) needs to be mounted to the local device. The configuration process is summarized as follows:
Create iSCSI on Windows server 2008 R2

First, set the forward and reverse records of the ESX host on the DNS. If you do not want to set them, modify the host file.
Enter the Administrator account of the VC host to go To the VC console.
First, create a data center and rename it to VMware.
Add hosts to the VC console to manage ESX hosts using VC.
Enter the ESX host name a
