Windows Azure Platform Family of articles Catalog　　This article describes the domestic azure China by the century connected operation　　Readers familiar with the Azure platform understand that the IOPS per disk of Azure VMS is 500. We take the D-series VMs as an example, and the IOPS information is as follows: virtual machine type CPU RAM temp disk number of external disks IOPS D1 1 3.5GB 50GB 2

keys that need to be retrieved, which means that the keyspace size does not affect performance. Typically, you use the Mget command line to retrieve more than 100 keys at the same time, so that you can avoid network delays as much as possible, rather than doing multiple get operations in a loop. We now have two Redis servers, using master-slave copy mode. These two nodes have the same configuration and are Xeon [email PROTECTED],128GB,SSD. T

, the data is still stored safely in the data volume container. In addition, Docker supports multiple storage methods in the form of plug-ins. With volume plug-ins (volumeplugin), Docker containers can now host directories, software-defined storage (such as Glusterfs and Ceph), cloud storage (such as cloud storage provided by public clouds such as AWS and GCE), and storage management solutions (such as flocker, etc.). Persistent volume and persistent volume requests Docker provides a mechanism

After some investigation, we decided to use Redis. The complexity of all our operations is O (1) or O (n), and n represents the number of primary keys we retrieve. This means that the size of the primary key space does not affect performance. When the number of primary keys retrieved at one time is greater than 100, we mostly use the Mget command, which ignores network latency when compared to using multiple gets in a single loop. We recently ran

It is well known that after the upgrade of SSD, the speed and performance of the computer have been greatly improved. However, some users upgrade SSD, speed and performance improvement is not obvious. The reason is that the SSD is not properly used and the operating system is installed. The common problem is that the 4K is not aligned, does not turn on the trim,

Q: Vsan needs to use SSD, what's the use of it? A: SSD is used for read caching (70%) and write Buffering (30%). Each write will go to SSDs first, and then cancel the staging to the HDD later. Q: When you create a VSAN virtual machine storage Policy, when should you use the "allowed number of failures", when should use "stripe width". A: The number of allowed failures is related to availability, and you c

In addition to Chromebook pixel (pixel is still a well-deserved performance champion), C720 is the best Chromebook I have ever experienced in terms of operating speed and sensitivity.

Chromebook Notebook momentum can be said to be more and more strong, many traditional PC manufacturers are beginning to launch their own Chromebook notebook. At CES January this year, we saw Toshiba Chromebook for the first time, and it was very possible to be a star in the growing Chromebook market at that time, both in appearance and in the performance of the product impressed us. Now, Toshiba Chromebook has been officially listed, the price of 279.99 U.S. dollars (about 1735 yuan), seems to b

The file system on Linux is generally EXT2 or EXT3, but this article is not ready to talk about them directly, but I want to combine the Linux operating system and from the foundation of the file system-the hard disk to start, step-by-step understanding of the Linux file system. 1.

2018 Storage Technology Hotspots and trends summary Over the past six months, I have read more than 30 papers and insisted on writing a Newsletter every 1-2 weeks, most of which are related to storage. Here is a summary today for you as a reference to understand the hotspots and trends in storage technology. This article contains new technical areas, such as Open-channel Ssd,machine Learning for Systems, as well as recent developments in the old topi

the difference between SSD and common hard disk In fact SSD solid-state drives are solid-state storage, belong to flash memory, long service life, not easy to damage, strong earthquake resistance. The disadvantage is: The price is expensive, the capacity is small. Ordinary hard drive inside a platter, work through high-speed rotation to read and write information, very afraid of vibration, easy to damage,
