Earlier this morning, Fujitsu said it is now offering new 50 PB-plus scale-out storage arrays for very large enterprise data, the CD-10000.

Appropriately called the Eternus CD-10000 Hyperscale Storage System, the new product uses Ceph, an open source software that presents file, block and object storage elements from a distributed cluster of object storage nodes across which data is striped.

Theoretically, Ceph can scale up to 1 exabyte, so there is lots of room to grow. Hardware-wise, the CD-10K supports 224 nodes which live in standard 19-inch racks and communicate via dual 40Gbit/s InfiniBand links.

Front-end access is via a 10 GbitE LAN and its resources can be accessed via KVM, Swift and S3.

The system’s usable capacity depends upon the number of data replicas, two or three for example, set up to protect against data loss.

Ceph doesn’t use RAID which is a good thing with around 13,400 disk drives in a 224-node system configured for capacity, as RAID rebuilds from disk failures would be constantly taking place.

Replication is used instead and the system self-heals and has zero downtime according to Fujitsu. The protection level can be boosted by increasing the number of replicas, from one to two to three or even four.

Fujitsu says the storage array can last a long time as components are refreshed with newer technology. Newer nodes can be swapped in with old nodes remaining or being retired.

The software takes care of moving data around to use the new nodes. There are three types of nodes:

  • Basic node with 2 Xeon CPUs and 12.6 TB raw capacity using 16 x 900 GB 2.5-inch 10,000 rpm SAS disk drives and a PCIe SSD for caching, journalling and metadata.
  • Capacity node with 252.6 TB of raw capacity from 60 x 3.5-inch 7,200 rpm SATA disk drives plus 14 x 900 GB SAS drives.
  • Performance node with 34.2 TB of raw capacity using 10K rpm SAS 2.5-inch spindles and PCIe SSDs.
  • The company says enterprise customers get the open source advantages of low cost, fast development and anti-locking advantages while having a single throat to choke for end-to-end maintenance and support.

    The company says it is working with partners and customers to add system applications to the CD-10K such as cloud services, file sync and share, archiving and iRODS data discovery.

    This is a heavyweight big data system for customers with vast data repositories such as CSPs, universities, financial and public institutions with cloud and cloud-scale projects, telcos and enterprises adopting OpenStack-– Ceph being the core object storage in OpenStack.

    Fujitsu says the CD-10K can be a single aggregating silo for block, file and object data and that it is making Ceph usable by enterprises.

    If you are looking at systems using Ceph, GPFS, Lustre, Gluster or DDN's WOS, then the CD-10K should be on your inspection list.

    The CD-10K’s minimum configuration has four nodes. It will get file storage capability in early 2015.

    Seagate said earlier this morning that it's currently demonstrating its new Kinetic disk drives at the OpenStack summit in Paris.

    Seagate says it has a rather broad support for its proprietary, single-source technology.

    To be sure, Kinetic is new disk drive technology that is directly addressed over Ethernet using Get and Put-style object storage commands using an open source API.

    The concept is that applications can directly use banks of these drives without having to go through complex filesystem software stacks or block access protocols and storage array controllers, making the whole process about 15 to 18 percent faster.

    Seagate marketing vice president Scott Horn claims that cloud service providers can simplify infrastructure, improve scalability and reduce costs by using Kinetic drives.

    Seagate says its new drive is getting support from various respectable businesses like AOL, Digital Sense and HP.

    AOL's chief architect for storage operations, Dan Pollack, provided a quote for Seagate, saying the new drive "will help AOL improve data centre efficiency by reducing the number of servers required to store data for modern enterprise applications" and will improve total cost of ownership "when storing the enormous data sets required by those applications, while simplifying management and reducing the effort required to operate reliable data storage systems".

    Michael Tran, Digital Sense's CTO, provided a quote as well-- "We are seeing up to a 75 percent reduction in costs as compared to our current storage systems."

    You can see the new drives at booths D-11 and E-48 at the Palais des Congres in Paris this week until Friday.
