Instructions for completing this work can be found at the GParted site or the Ubuntu forum. If you want, you can also use the GParted Live CD.If you choose to back up your system to an external USB drive, you need to be ready to wait. In our case, the estimated time is about four hours.

Major storage Architectures direct-attached storage Linux supports a large variety of DAS interfaces, including old standards like parallel advanced technology Attachment (at A)-integrated Drive Electronics [Ide]/ata-parallel SCSI, and Fibre Channel as well as new storage interfaces like serial a Ttached SCSI (SAS), serial ATA (SATA), and external SATA (ESATA).

of bandwidth, and if you are using a FA SAN, you need at least 2 8GB HBA cards to have 4GB of bandwidth. Whatever the way, when designing VMware vsphere virtualized networks, be sure to ensure that the number and bandwidth of network cards meet your business needs. Be aware, however, that VMware vsphere does not support wireless networks.3. Storage planningIf you are using a single ESXi host, and the host is connected to multiple hard disks, such as Dell R520, then we can use the native storage
First, the benefits of unlocking the hard drive AHCI mode:
1. Hard drive AHCI mode can greatly shorten the hard disk search times and shorten the data lookup time, so that the disk under multitasking can be used efficiently. Greatly improve the efficiency of frequent read and write hard drive programs, especially when running a large game or software, the speed of reading and writing has been significantly improved.
2. Can reduce the temperature of the hard drive, read the noise when the disk.

3. Set the time zone
The default is Greenwich Mean time, so it may be different from local time when the current time is displayed. PHP provides a function date_default_timezone_set () that can modify the time zone.
The syntax format is as follows:

String UrlEncode (String str)
Returns a string, in addition to the-_ in this string. All non-alphanumeric characters are replaced with a percent sign (%) followed by a two-bit hexadecimal number, and the space is encoded as a plus (+).
