Capricorn Technologies introduced the PetaBox Product Family, designed for massive data storage. The PetaBox supports petabyte-class storage with state-of-the-art density, low power consumption and a low total cost of ownership. The PetaBox is scalable from individual terabyte nodes to a full petabyte cluster. A single 19-inch rack can support up to 64TB of raw disk space, a density achieved through a design that consumes as little as 50 watts per terabyte. Four models of PetaBox currently are available: the GB1000, a 1.0TB node; the GB1600, a 1.6 TB node; the TB40, a 40TB rack; and the TB64, a 64TB rack. Each node has four hard drives per node, an ATA interface, rotational vibration compensation, 8MB of cache, 8.5ms of typical latency and an EZ-Latch disk mounting system. Nodes also feature a 1GHz VIA C3 CPU, up to 1GB of DDR266 RAM, two USB 2.0 ports, 10/100 or 10/100/1000 Ethernet and an optional 16x2 character LCD.

Free Webinar: Hadoop
How to Build an Optimal Hadoop Cluster to Store and Maintain Unlimited Amounts of Data Using Microservers
Realizing the promise of Apache® Hadoop® requires the effective deployment of compute, memory, storage and networking to achieve optimal results. With its flexibility and multitude of options, it is easy to over or under provision the server infrastructure, resulting in poor performance and high TCO. Join us for an in depth, technical discussion with industry experts from leading Hadoop and server companies who will provide insights into the key considerations for designing and deploying an optimal Hadoop cluster.
Some of key questions to be discussed are:
- What is the “typical” Hadoop cluster and what should be installed on the different machine types?
- Why should you consider the typical workload patterns when making your hardware decisions?
- Are all microservers created equal for Hadoop deployments?
- How do I plan for expansion if I require more compute, memory, storage or networking?
