Rackspace last week released a new storage service-block storage (Cloud blocks Storage). This service complements Rackspace's existing cloud storage services, especially for databases and other applications that require high speed I/O. Users can choose traditional disk storage, or more high-performance SSD. In terms of price, disk storage is 15 cents GB Month, SSD Price is 70 cents GB month.

Users can customize the size of partitions from 1GB to 1TB and can create multiple partitions at the same time. It is important to note that even if users use only 1 1GB partitions, they must purchase 100GB of space. Rackspace says it does not offer SSD choices like some of its rivals, such as Amazon. In addition, disk snapshots are stored in the cloud at a price of 10 cents GB months.

Rackspace emphasizes that it provides ssd,amazon as well as high-performance storage services, but does not use SSD. Amazon's resilient block storage EBS service allows users to choose between two ways to build partitions: Standard mode and self-service IOPS mode. In self-service ioPS mode, users can set the IOPS value of a partition. Amazon claims it can deliver up to 1000IOPS. Rackspace does not specify the IOPS value of its SSD storage. Many cloud service providers offer block storage services ranging from 10 cents to 80 cents GB months.

Rackspace's new service is based on OpenStack's Cinder API development. Because of OpenStack based on open source, "users don't have to worry about being locked up by a vendor," says Racespace's CTO John Engates. "If they want to replace another OpenStack vendor, build a private cloud, or go to a competitor, they don't have to pay a penny if they're still using the cinder API because they have the same access." ”

Rackspace says the block storage service is now available in its two data centers in the United States and in London's data centers.
