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.

Practical Task Scheduling Deployment
July 20, 2016 12:00 pm CDT
One of the best things about the UNIX environment (aside from being stable and efficient) is the vast array of software tools available to help you do your job. Traditionally, a UNIX tool does only one thing, but does that one thing very well. For example, grep is very easy to use and can search vast amounts of data quickly. The find tool can find a particular file or files based on all kinds of criteria. It's pretty easy to string these tools together to build even more powerful tools, such as a tool that finds all of the .log files in the /home directory and searches each one for a particular entry. This erector-set mentality allows UNIX system administrators to seem to always have the right tool for the job.
Cron traditionally has been considered another such a tool for job scheduling, but is it enough? This webinar considers that very question. The first part builds on a previous Geek Guide, Beyond Cron, and briefly describes how to know when it might be time to consider upgrading your job scheduling infrastructure. The second part presents an actual planning and implementation framework.

With all the industry talk about the benefits of Linux on Power and all the performance advantages offered by its open architecture, you may be considering a move in that direction. If you are thinking about analytics, big data and cloud computing, you would be right to evaluate Power. The idea of using commodity x86 hardware and replacing it every three years is an outdated cost model. It doesn’t consider the total cost of ownership, and it doesn’t consider the advantage of real processing power, high-availability and multithreading like a demon.
This ebook takes a look at some of the practical applications of the Linux on Power platform and ways you might bring all the performance power of this open architecture to bear for your organization. There are no smoke and mirrors here—just hard, cold, empirical evidence provided by independent sources. I also consider some innovative ways Linux on Power will be used in the future.Get the Guide
