SVM new features

solaris_enginee

Sun\'s Volume Manager has evolved a lot over the years. In name\r\nalone, it was once known as ODS (OnLine Disk Suite), then\r\nSDS (Solstice Disk Suite), then SLVM (Logical Volume Manager),\r\nand now in Solaris 9, it is called SVM.\r\n\r\nIn Solaris 9, it is literally built-in. If you install even the basic \r\nSolaris\r\nOS (the user collection) you get SVM, for free, integrated with the\r\nOS. It supports soft partitions and device IDs (two of the \"must have\"\r\nfeatures that many admins have been screaming for) and a new mgmt\r\ninterface. And the built-in/free UFS+ filesystem supports journaling\r\n(aka: logging), QuickIO-like performance (we relaxed some POSIX\r\nrules back in Solaris 8, and added some other performance tricks,\r\nsimilar to QuickIO), and online filesystem growth.
