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.

Pick up any e-commerce web or mobile app today, and you’ll be holding a mashup of interconnected applications and services from a variety of different providers. For instance, when you connect to Amazon’s e-commerce app, cookies, tags and pixels that are monitored by solutions like Exact Target, BazaarVoice, Bing, Shopzilla, Liveramp and Google Tag Manager track every action you take. You’re presented with special offers and coupons based on your viewing and buying patterns. If you find something you want for your birthday, a third party manages your wish list, which you can share through multiple social- media outlets or email to a friend. When you select something to buy, you find yourself presented with similar items as kind suggestions. And when you finally check out, you’re offered the ability to pay with promo codes, gifts cards, PayPal or a variety of credit cards.Get the Guide
