BKJIA San Francisco site report] at the 2009 Oracle Global Conference OpenWorld, OOW, everyone is not new to Oracle new database machine Exadata V2 challenge IBM database machine pureScale. However, the current understanding of the Exadata V2 database machine in the industry remains in many concepts. For enterprise users, it is very practical to know the quotation of the new Oracle Database machine Exadata V2. Maybe Oracle didn't want to show the price of Exadata V2, but the reporter in front of

Main wiring Area (MDA) MDA is the core of the entire data center and also the central distribution point of the data center structured cabling system, and the total distribution area is equipped with core Ethernet switches and routers, core storage Area network (SAN) switching devices, PBX devices, network management devices, and access devices. The total wiring area also includes a primary cross-connect (MC), which is used to establish a connection between the backbone cable and the c

Because the 3.x series no longer support mongrel, so the use of Nginx+passenger to do load balancing; previously had Nginx+mongrel,puppet version is 2.7 series, so still can use; Environment Description: Operating system: CentOS 5.8 64-bit Puppet version: 3.1 series 1, upgrade Ruby to 1.8.7, install RubyGems # RPM-UVH Http://rbel.frameos.org/rbel5 # yum install-y Ruby RubyGems ruby-devel.x86_ 64 2, install Puppet server # RPM-IVH Http://yum.puppetlabs.com/el/5/products/x86_64/puppetlabs-rel

To ensure the reliability of the storage file, HDFs decomposes the file into multiple sequence blocks and saves multiple copies of the data block. This is important for fault tolerance, where a copy of a block of data can be read from another node when one of the data blocks of the file is corrupted. HDFs has a "rack-aware" strategy for placing a copy of the file because the same rack bandwidth is greater

There are also large hospitals and many small clinics and physician clinics. The data center technology of two major teaching hospitals at Harvard Medical School was merged five years ago. "In a short time after that, we merged other medical centers and our cabling infrastructure was working well at an estimated gro

Snitch determines which data center and rack the node belongs to. Snitch notifies the Cassandra network topology to request a valid route, and allows the Cassandra to distribute replicas when the server is added to the data center or rack. In particular, how replication policies place replicas is based on the information provided by the new snitch. Cassandra does not put a copy in a

file Idnode in the Hadoop file system, where the file contains the file's modification time, access time, block size, and a file block information. The information contained in the folder includes the modification time, access control permissions, and so on.
