The upgrade cost reached $45000000 and was the biggest transformation investment since Linode was founded (11).
SSD StorageThe SSD array storage system used in Linode is not a popular hybrid hard disk at present, and it uses the server-level SSD hard disk with battery back-up power. The price is very expensive.

In vSphere 5. x adds a new vSAN feature. However, this feature requires at least one SSD on the physical machine as the cache, and requires no Raid or the Path-Thru feature of the Raid card to be enabled. However, some RAID cards do not have the Path-Thru function, or the server does not have SSD. This method can be used to fool vSphere and forcibly mark a disk type as

A lot of people have changed the SSD hard disk in the short term speed up quickly, but after a few months found the speed slowed. So what happens when the SSD slows down? Here are the SSD speed slow solution, and the C disk cannot be 4K aligned with the SSD hard drive (data lossless)
Because the format of the h
I am preparing for the test recently. I need to check which machines are attached with ssd hard disks. I saw many methods in a circle on Google, but they are all in the fog and I don't know how to determine them. Ssd disks seem to use scsi interfaces, so they cannot be determined based on the drive letter name. At last, eric told the lsscsi tool in the group that it was very simple and displayed directly. N
Landlord office computer, originally only configured a piece of mechanical hard disk, with always very uncomfortable, so persuaded the leader to add a block SSD SSD.The operation is as follows:1, the PE under the partition format of the new solid-state drive, the original mechanical hard disk of the C-disk ghost backup and restore to a new solid-state drive;2. Remove the original C drive letter (drive letter: C, D, E, F) and cancel the active state;3.
Dell is still making different improvements to its most popular netbook Mini10, in addition to the 6-core battery option launched a few weeks ago. In 7th day of this month, the Mini 10 version of the customized Ubuntu system and SSD hard drive was launched, starting at $399. The Ubuntu Mini10 system also provides additional hard drive options, including 32 GB and 64 gb ssd hard drives at an additional price
Introduction:This paper mainly introduces several image matching algorithms based on gray scale: mean absolute difference algorithm (MAD), absolute error and algorithm (SAD), error square sum algorithm (SSD), mean error square sum algorithm (MSD), Normalized product correlation algorithm (NCC), Sequential similarity algorithm (SSDA). The following is explained in turn.Mad AlgorithmIntroduction mean absolute difference algorithm ( mean Absolute Dif

Because of work, sometimes two computers are needed to work, and most people engaged in development are those pursuing computer performance, so the laptop is naturally not light, not to mention the two.
I have been suffering from two computers for more than half a year, and finally made up my mind to install a system into a mobile SSD, carrying a non-hard drive computer and adding two mobile SSDS to reduce the burden.
After one day's exploration, many
Linux SSD optimization policy 1. do not use a file system with logs. If you have the ability, consider a file system that supports ssd, such as ubifs. If not, use ext2 www.2cto.com 2. disable noatime nodiratime of the file system, because the access time will increase ssd write, there is no need to modify/etc/fstab, for example, change/dev/hda9/data ext2 defaults
