Storage system touts 56 petabytes capacity

Keywords:ETERNUS  petabytes  RAID  storage system 

Fujitsu Limited recently launched the ETERNUS CD10000, a storage system ideal for hyper scale data volumes.

The storage capacity of the ETERNUS CD10000 can be scaled out to 56 petabytes just by adding storage nodes, which combine discs with controllers. This makes it possible to meet the storage needs for data volumes that, in recent years, have been growing explosively in the form of documents, images and video, mainly reference material.

Moreover, in addition to ensuring redundancy of data among nodes for high availability, the system automatically distributes data so that processing loads are not concentrated on any given node. As a result, the design work required for redundancy when using conventional RAID (Redundant Arrays of Inexpensive Discs ) is no longer needed, making it easy to store petabyte-scale volumes of data.

Features of ETERNUS CD10000

1. Scalable up to 56 petabytes

The system's capacity and performance can be scaled out by adding storage nodes, which combine disks with the controllers that control data input-output. Up to 224 nodes can be configured, delivering a massive level of storage capacity of up to 56 petabytes. Moreover, nodes can be added without shutting down the system, enabling the capacity of the system to be scaled up in a flexible and timely way as processing levels increase.

2. Superior availability and operability

The system employs the Ceph open source distributed file system software, which, in addition to ensuring redundancy of data among nodes, automatically distributes data so that processing loads are not concentrated on any given node. As a result, the design work required for redundancy when using conventional RAID is no longer needed, and high availability is achieved.

In addition, with the Ceph distributed file system, the movement of data required when changing the system's configuration is kept to a minimum. Accordingly, compared to ordinary distributed file systems, in which everything needs to be reconfigured, the impact on performance is significantly reduced.

3. Easy migration

When exchanging ETERNUS CD10000 hardware, just by swapping out old nodes for new nodes in sequence, data is transferred to the new nodes without downtime. When changing the configuration of nodes, the controller automatically restores data redundancy and automatically adjusts the load distributions. As a result, in contrast to conventional storage systems, there is no longer a need to shut down the system for long periods of time or to conduct cumbersome data transfer operations.

4. Flexible access

This is Fujitsu's first storage product to support the object access method, which assigns a specific ID to content and manages it along with its attribute information. This enables flexibility in content management based on the attribute information, such as the type of data, storage time and replication policies. In addition, the system supports the block access method, which reads and writes data in block units of a specified size, making it possible to select the access method in accordance with the application.

Furthermore, it supports the OpenStack open source software, so it can be used as the storage system for private cloud platforms that were built on, and run on, OpenStack.
