On scaleio, xtremsw cache can be deployed in two ways: Xtremsw cache is used inside each server as cache-cache is implemented under scaleio Data Server (SDS), which is similar to the concept of vnx fast cache or Vmax cache in the traditional SAN world. Use the xtremsw cache on the application side as the cache-perform the cache under scaleio Data Client (SDC). This concept is similar to the server side caching in the data center. Caching in

Build one of the basic Linux frameworks Building a Linux by yourself can not only deepen your understanding of Linux, but also help you learn embedded Linux. The process of building a Linux (kernel compilation, file system creation, graphical interface, driver, etc.) is basically the same as that of developing an embedded Linux.1. Development Environment Redflag Linux 6.0 VMware 7.1.3build-3242852. Add a disk Add a new virtual hard disk and select "ide" as the hard disk type, as shown in: Note:

In SUSE Linux 10, raw devices bare devices are unformatted partitions or disks, which are also called raw partitions ), A special character device that is not read by Unix through a file system. It is read and written by the application. A device that is not directly managed by the operating system without being buffered by the file system. I/O efficiency is improved because I/O is managed across operating systems.If Oracle 10g RAC is installed on SUSE Linux 10, Oracle 10g does not support stori

Disk Management -- Raid1 + 0 volume + LVMPreparations Take two disks as an example: SDB and SDC. Three primary partitions are created for each hard disk. Sdb1 1g, sdb2 1g, sdb3 1g Sdc1 1g, sdc2 1g, sdc3 1g Step 1: Create sdb1, sdc1, sdb2, sdc2, sdb3, and sdc3 as raid1, md1, md2, and md3 respectively. Step 2: Create md1, md2, and md3 as raid0 volume md0 Step 3: Use LVM volume management to create the raid0 volume md0 and create the LV logical volume st

found, but the process of invoking the deleted file continues to execute normally and the content can be read and written correctly from the file. Why is that?This is because the RM operation only reduces the file I_nlink, if there is no other link i_nlink is 0, but because the file is still referenced by the process, so the file corresponding to the I_count is not 0, so even if the RM operation, but the system does not really delete the file, When only I_nlink and I_count are 0, the file is ac
