Orion Multisystems announced the availability of the DS-96, a 96-node deskside cluster workstation. Stackable up to four systems, the DS-96 boots 96 individual nodes as one system using a single on/off switch. It does not have special cooling requirements, and the maximum power draw is 1,500 watts from a standard power outlet. The entire system is based on eight Orion processor array boards, with each board composed of 12 individual nodes on a private network. Each node has its own x86 processor, chipset, memory, optional disk drive and networking capability. Other features include dual 10-GigE fiber cards and a 12-port GigE switch, a DVD/CD-RW and one 2.5" hard drive on the head node, and one optional 2.5" hard disk drive per node. The DS-96's software is based on Fedora Core 2.

Vexira Antivirus for Mail Server is a content security application that provides scalable protection from viruses, spam, spyware and other malicious applications. It can integrate directly with many e-mail systems, or it can act as its own SMTP relay server to shield the e-mail server itself from attack. Five different checks are performed on e-mail: file gate, file filter, field filter, virus filter and spam filter. Each user or domain owner can have specific configurations and rule sets. Vexira also offers scalable LDAP support. Vexira contains several embedded e-mail defense features, including DoS protection, blacklisting, zip-of-death protection and mail-bomb protection. Vexira supports header modification, subject modification and custom message marking, and it offers a real-time overview application of current operations.

Coraid's EtherDrive Storage appliance now is available for Serial ATA disk drives. The refined chassis design includes 15 hot-swap drive bays that accommodate standard SATA disk drives. The new shelf offers a dual-GigE interface, redundant hot-swap power modules and fans. Fully populated drive bays using 400GB disk drives yield 6TB of storage, but using 500GB drives, the new shelf provides 7.5TB of storage. SATA EtherDrive Storage appliance uses the AoE (ATA over Ethernet) protocol. Using Ethernet connections, EtherDrive Storage Blades appear to servers on the network as locally attached disks. In addition, the EtherDrive Storage appliance can be assembled into large RAID sets and storage volumes.

SGI announced the newest member of the Silicon Graphics Prism product line, the Prism Deskside Visualization System. The Prism products offer visualization capabilities for tackling problems that generate massive data sets. Based on SGI's scalable, shared-memory visualization architecture and Altix high-performance servers, the Deskside Prism features dual Itanium 2 processors and up to 24GB of memory in a deskside form factor. The Deskside Prism can drive displays with up to 10 million combined pixels, as the system's dual ATI FireGL graphics processors simultaneously can serve four full bandwidth channels. With the Deskside Prism, users can transparently access and share data and resources from cross-platform clients connected across networks for efficient collaboration.

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.

Built-in forensics, incident response, and security with Red Hat Enterprise Linux 6
Every security policy provides guidance and requirements for ensuring adequate protection of information and data, as well as high-level technical and administrative security requirements for a system in a given environment. Traditionally, providing security for a system focuses on the confidentiality of the information on it. However, protecting the data integrity and system and data availability is just as important. For example, when processing United States intelligence information, there are three attributes that require protection: confidentiality, integrity, and availability.

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?
