Although Windows 7 is supported by the XPS 9350 series, it is not easy to install. If you follow the normal process of writing Windows 7 MDSN ISO to a USB flash drive, and then booting the installation, first of all, because of the lack of NVME driver can not find the hard disk, and after solving this problem, the lack of USB 3.0
While the installed rate of Windows 10 systems is rising, the classic Windows 7 still has a large user base. Especially in China, Windows 7 is still the preferred system for many computer users.Enduring Windows 7However, since the era of the Skylake architecture processor, users have found a lot of problems in installing Windows 7 on a new computer. In fact, this is mainly caused by the lack of some necessary drivers for native Windows 7:Previous generation Skylake platform to install Windows 7,

First of all, from the hardware appearance, This is a standard-sized, half-height, half-length PCIe card. It is compact and can be placed on any server, which is basically compatible with all servers. In addition, PMC has made several innovations on the interface layer connected to the host. 4. The left side shows the native interfaces of the current application, all of which are based on blocks. Therefore, we provide an

protocol support, such as NVMe, which are not available on SATA E interfaces. It can be said that u.2 is actually SATA E's complete body.
Why is it called u.2?
U.2 Interface Board End Interface
M.2 was first called NGFF. U.2 was first called SFF-8639. SFF-8639, because this name is too uncommon, obviously not easy to be remembered by the user, this temporary address soon has a formal name: u.2.
What are the features of the u.2 int
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 +
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
Storage software for disk design does not need to consider the performance impact of competitive locks. Disk storage software has a performance bottleneck in disk, and disk Jitter introduces a significant performance drain. Therefore, the design of traditional storage software is not particularly concerned with the efficiency of the processor. Once the performance tuning of a storage virtualization software, the lock competition has done a lot of optimization, and finally did not achieve perform
Next we will mainly explain the content of NFSv4. What are the features of the fourth NFS version? Let's take a look at it. NFS is composed of server software-for example, software running on NetApp storage-client software requiring access to network storage and running on the host. proper operations require that the two ends of the connection, that is, the client and the server are mature and have been correctly implemented. although
, this is the core challenge of NAS backup, and the network performance of the NAS is uneven. Q: Is ndmp a good choice for NAS backup? How does it work? Answer: NDMP was introduced to the industry about 10 years ago. That's when NetApp started to become active, and NetApp NAS devices are the kind of equipment that you can back up with headaches. Then people would ask, "How exactly do you back it up?"
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
