The Oracle Exalogic Elastic Cloud

Everybody likes talking about the weather. In the computer world that seems to mean talking about cloud computing. The latest cloud on the horizon is the Oracle Exalogic Elastic Cloud, announced yesterday (Sept 19th) at Oracle OpenWorld 2010.

The Exalogic Elastic Cloud is targetted at Enterprises that want to create their own private clouds. Exalogic installations consist of up to eight 42U racks. Each Exalogic rack contains hot-swappable compute nodes, a disk subsystem, multiple 1 and 10 Gigabit Ethernet ports, and a high-bandwidth InfiniBand interconnect for connecting the components to each other and to other Exalogic racks or to Exadata Database Machine racks. Exalogic configurations are designed to be redundant.

Each 1U "node" in an Exalogic rack consists of two Xeon chips. Each Xeon chip is a 6-core processor running at 2.93 GHz. Each node has redundant InfiniBand connections. Each node also contains two solid-state disks (SSD) for the operating system and for local swap space.

An full rack would contain 360 CPU Cores, 2.8 TB (TeraBytes, 1 TB = 1024 GB ) of RAM, 960 GB of SSD, and 40 TB of SAS (Serial Attached SCSI) disk. Sorry though, there's no video card so you can't use this for your desktop.

Due to the use of the InfiniBand interconnect the components of an Exalogic installation can be interconnected in numerous ways. This allows the system to be subdivided as needed for configuring your private cloud. InfiniBand is referred to as a switched fabric communications link, it uses switches to interconnect different components connected to the fabric. InfiniBand grew out of the merger of "Future I/O" (Compaq, IBM, and HP) and "Next Generation I/O" (Intel, Microsoft, and Sun) in 1999.

Exalogic systems run either Oracle Solaris 11 or Oracle Linux 5 (Red Hat Enterprise Linux). The management software is called the Oracle Elastic Cloud Software and it uses the Oracle WebLogic Suite. The Suite includes:

  • Oracle Coherence - Java based data caching, data replication, and distributed computing services.
  • Oracle JRockit - a Java Virtual Machine (JVM) developed by Appeal Virtual Machines, later bought by BEA Systems.
  • Oracle HotSpot - another JVM developed by Sun Microsystems.

For more information, and to read Oracle's name a few more times, see the whitepaper Oracle Exalogic Elastic Cloud: A Brief Introduction.

Just another FUD

Have you ever used an email acct with an IMAP client & server? Welcome to the cloud, clueless.

Uh?

"Multics (Multiplexed Information and Computing Service) was an extremely influential early time-sharing operating system. The project was started in 1964. The last known running Multics installation was shut down on October 30, 2000 at the Canadian Department of National Defense in Halifax, Nova Scotia, Canada.[5]"

If the "cloud" were so good it wouldn't be necessary to promote it so heavily.

I can only hope that all this "cloud" stuff - IMHO just a rehash of Multics - goes away into oblivion as quickly as possible... AFAIK, the "cloud" is insecure, unreliable, and *unnecessary*. Overall, a bad idea. But maybe I am wrong, and the "cloud" is the best thing to ever happen to IT since the discovery of the electron... Time will tell - but I won't bet on the "cloud".

Fabric-Based Computing Enables Optimized Hyperscale Data Centers

Today’s modular x86 servers are compute-centric, designed as a least common denominator to support a wide range of IT workloads. Those generic, virtualized IT workloads have much different resource optimization requirements than hyperscale and cloud applications. They have resulted in a “one size fits all” enterprise IT architecture that is not optimized for a specific set of IT workloads, and especially not emerging hyperscale workloads, such as web applications, big data, and object storage. In this report, you will learn how shifting the focus from traditional compute-centric IT architectures to an innovative disaggregated fabric-based architecture can optimize and scale your data center.

Red Hat White Paper: Using an Open Source Framework to Catch the Bad Guy

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.
