A way to reduce storage costs



A perennial problem with storage is how to deal with escalating requirements in a smooth, manageable and non-disruptive manner. A new-generation of smart storage architectures uses clever solutions to blow economic laws relating to the cost of data storage out of the water.

Data, data and yet more data … modern organizations have to deal with mountains of data, which only continue to grow. This poses critical problems: increased requirements for scalability, greater complexity and higher costs, to say nothing of the major problems if data goes offline during a migration between systems or when data storage limits are reached. These are the challenges which Fujitsu has to address when working with customers and partners in data-intensive sectors, such as

for data distribution. The data, along with several copies, is automatically distributed across the hard disks and the storage nodes throughout the entire system. This results in a fault- online services, finance, logistics, science, education and government.

The most easy to deploy and operate Ceph package in the industry

The provision of reliable data services at low cost is crucial for many organizations and the second-generation ETERNUS CD10000 S2 storage system gives customers the tools that they need. The system is based on Ceph, the leading open source storage software, industry standard hardware and integrated management tools from Fujitsu. All components are evaluated, optimized and perfectly harmonized with each other. It represents an autonomous and self-healing system that identifies changing events and automatically takes appropriate action in response. Furthermore, it has an intelligent mechanism tolerant architecture in which data is automatically and quickly restored if hard disks or complete storage nodes should ever fail.
New software and hardware options are continuing to drive down the costs of storage — up to ten times lower than was previously possible. One example is new storage units which fit up to 240 terabytes of data in a box of 4HU height which is 2.5PB in a rack.

So how do you reduce the costs of data storage? One solution offered by the ETERNUS system is a new kind of storage modules. “Flex Nodes” and “Density Nodes” help to better focus on performance-optimized or capacity-optimized workloads. Flex Nodes are primarily intended for scenarios where IO- or throughput- performance is key, and they ensure a high degree of scalability. Density Nodes are precisely optimized for the storage of large volumes of data at the lowest possible cost per terabyte. By using advanced data protection methods like Erasure Coding the capacity needs for data redundancy can be shrunk by 75%. This approach allows for data storage at prices of EUR 0.007 to 0.013 per gigabyte per month, and it also takes into account scenarios involving unpredictable data growth.

Longer Lifespan and Easy Backup and 2-Site-DR

New storage systems such as the ETERNUS CD rely on optimum management capabilities. As such, the management node of the appliance delivers unified management capabilities, making it easy to replace old hardware with newer options without downtime. This also increases the system’s lifespan compared with traditional RAID arrays. Further optimization is provided in the form of improved support for disaster scenarios: the development of an innovative “backup-in-a-box” concept protects large data volumes. IT administrators are subsequently in a position to respond quickly and adequately to major failures. For even higher resilience, two-site solutions can be realized so that cost-effective business continuity is guaranteed even in the event of a disaster.
