Calculating the PG Count formula for a single poolPoolpgcount= ((TARGETPGSPEROSD)? ( Osdnumber)? (datapercent)) /poolsizeParameter introduction name Description Notes Pool PG Count Number of PG in a single pool Target PGs Per OSD Number of PGS per OSD A) If the number of OSD in the future cluster is no longer basic, Target PGs per OSD =100b) If the number of OSD in the future cluster may increase to twice times

First, read the following concepts: the IDE hard drive starts with hd (now basically disappears, except for some older machines), and the SCSI hard drive starts with sd (now popular sata ). Floppy disk starts with fd (can be said to disappear directly ). The name is not the same as that of linux. Is counted from 0. (Sd0, 0) (why does it start from 0, because many foreign things start from 0 ). Disk C. (Hd0, 4 ). Disk D. Of course, this refers to (the

A hard disk partition consists of a primary partition and an extended partition, with a maximum of four partitions. If all the IDE Hard Disks are primary partitions and extended partitions, they are hda1, hda2, hda3, and hda4 respectively. If you want to have more partitions, you can perform logical division in the Scalable partitions. The initial partition starts with hda5. That is to say, hda1 -- hda4 is left to the primary partition and extended partition, and the logical partition must start

It has become fashionable for computers to upgrade their solid-state drives to enhance their speed and nuclear performance. However, a variety of different computers, can upgrade SSDs, how to upgrade SSD to achieve the speed of nuclear performance, but the biggest problem of upgrading SSDs. In order to meet the needs of upgrading the SSD friends, this computer upgrade SSD program is specially made, which is summed up as eight know-how. It can be said that most of the problems in upgrading SSDs c

basically no relationship. In this case, the first to introduce a common people do not often contact the concept: BER hard disk error rate, English is ber (Bit Error Rate), is a description of the hard disk performance of a very important parameter, is a measure of the reliability of the hard disk error. This parameter represents the data that you write to the hard disk and the probability of an unrecoverable read error while reading. From a statistical point of view is also relatively rare, i

networks (Sans) in one framework. The entire software system is connected to many open source applications such as Apache, Samba, LVM2, ext3, Linux NFS, and ISCSI Enterprise Target. Openfiler combines these ubiquitous technologies into an easy-to-manage, small management solution that is the front-end of a powerful WEB-based management interface.Openfiler supports CIFS, NFS, Http/dav, and FTP, but we will only use its ISCSI capabilities to achieve a low-cost SAN for shared storage components re

tag: OS uses AR Java data SP C on CTI 目前业界有很多MQ产品，我们作如下对比：RabbitMQ 是使用Erlang编写的一个开源的消息队列，本身支持很多的协议：AMQP，XMPP, SMTP, STOMP，也正是如此，使的它变的非常重量级，更适合于企业级的开发。同时实现了一个经纪人(Broker)构架，这意味着消息在发送给客户端时先在中心队列排队。对路由(Routing)，负载均衡(Load balance)或者数据持久化都有很好的支持。Redis 是一个Key-Value的NoSQL数据库，开发维护很活跃，虽然它是一个Key-Value数据库存储系统，但它本身支持MQ功能，所以完全可以当做一个轻量级的队列服务来使用。对于RabbitMQ和Redis的入队和出队操作，各执行100万次，每10万次记录一次执行时间。测试数据分为128Bytes、512Bytes、1K和10K四个不同大小的数据。实验表明：入队时，当数据比较小时Redis的性能要高于RabbitMQ

He was convinced that his mother gave him a blind man in the village, his life, his future is rich, but the wife can not marry before the age of 30.
