network SAN. If there are dozens of Virtual Machine VMS in the system), technically speaking, write the Virtual Machine File System (VMFS) to SAN storage, it is very helpful to integrate all vmdks into a single LUN. However, if the system has thousands of virtual machines, nas nfs is a more efficient network storage method. For example, NAS allows you to group similar VMDK files into different folders. One folder can store all desktop images, one folder can store all Microsoft Exchange servers,

new pfile through the spfile of the + ASM1 instance and try to start the + ASM2 instance. Similarly, the + ASM2 instance cannot be started. SQL> startup nomount pfile = '/tmp/init + asm2.ora '; The ORA-24324: service handle not initialized. ORA-01041: internal error. hostdef extension doesn't exist At the beginning of the year, it was suspected that it was a storage problem, so we began to check the storage status. This RAC uses the multipath + asmlib architecture. Status of multipath q

that keep data in cloud storage such as Amazon S3 run well at the microsession level, but most applications do not have. Solution to storage problems This means that containers will be only a small role in the future data center, only for developers or brand new cloud hosting microservice applications? We believe that the advantages of containers are extremely attractive, so that enterprise data centers cannot be ignored, and as you may have guessed, container data management products are stand

Microsoft SharePoint and Exchange. "Oracle FS1 has five core features, including automated tiered qos+ based on business priorities, application-based one-click Configuration, multi-application storage partitioning, high-performance converged architecture for all-flash design, and deep integrated design of Oracle software that can significantly improve storage efficiency," Sho Shunan said. ”With Oracle's data compression solution, Oracle FS1 can stor

With future upgrades to file system protocols, such as NFS (including concurrent NFS, or PNFS), will NFS potentially replace many of the existing proprietary file systems? Let's take digitalfilm tree for example, a company in Hollywood that provides post-processing and virtual effects services for the entertainment industry. The company employs products that include Apple Xsan, HP storageworks arrays, QLogic switches, and other storage vendors. They also use a hybrid operating system environmen

The file modification time on the NFS file system displays the problem of Solaris + NetApp storage. the user's home directory is placed on NetApp and mounted to the local through autofs. You can use ls-l to view the touch file in your home directory. the mtime (modifytime) column only displays the year, month, and day ,... the file modification time on the NFS file system displays the problem of Solaris +

appearance and reduce the actual network transmission efficiency. Thus ASPD needs to be improved. apsd (Automatic Power Save Delivery): ASPD is designed based on 802.11e. Set the concept of a service Period (SP) in 802.11e. We can simply understand that if a node occupies a channel, it formulates a service time, and in that time, the node can transmit multiple frames, in other words, a competition multiple transmission. In ASPD, there are two kinds of specific working modes in S-APSD a

Speed-limiting switches are typically on three or more switches, and the new switch model two-tier device since 2008 can achieve the QoS speed limit of 1Mbps, such as the Cisco 2960 series switches. After this, most of the domestic standard two-layer switches can be long speed limit, the accuracy of the basic can reach 1Mbps, such as ZTE's standard two layer, H3C standard two layer can do. Older Cisco standard two-layer switches such as 2950-class swi

ObjectiveMemory is not very good when, can only look at the previous article/notes to review again, but could not find the MQTT protocol about the subscription part of the description, very hard to find from Evernote, so the entire MQTT protocol notes, it is more complete.SUBSCRIBEIn general, after the client has successfully established a TCP connection, the client sends a connect message, and after the server-side authorization is allowed to establish a connack message connected to each other,

There are many ways to access the broadband network. At the same time, these methods also use different access technologies. Each new technology can solve the problem that the old technology cannot implement, here we will introduce the features and principles of these technologies. Last step Since June, China Telecom has opened a VPN service for major customers on the newly created CN2, marking the maturity of a new IP bearer network. This bearer network not only adopts the latest technologies

VSC is a plug-in that NetApp stores on vsphere vcenter 4 and is not a vsphere client plug-in, so it must be installed on vcenter. After installation and then login vcenter, there is a NetApp tab in the Datastore view. With VSC you can easily access NetApp storage and scan the ESX datastore on NetApp storage, whether i

a viable option, but applications such as databases directly choose to use logical volumes to implement snapshots because they cannot be managed by snapshot technology at the file system level. In general, there is no need to implement snapshots at the application layer, which can be implemented using the underlying file system or volume Manager interface for backup mechanisms, but requires a temporary pause to ensure snapshot data consistency. In general, software-layer-based snapshots are eas
