Solaris 11


Solaris 11 is here:

As we can read on Jeff Victor’s Blog (Principal Sales Consultant at Oracle Corp) these are some of the cool new features:
Software management features designed for cloud computing
The new package management system is far easier to use than previous versions of Solaris.
·       A completely new Solaris packaging system uses network-based repositories (located at our data centers or at yours) to modernize Solaris packaging.
·       A new version of Live Upgrade minimizes service downtime during package updates. It also provides the ability to simply reboot to a previous version of the software if necessary - without resorting to backup tapes.
·       The new Automated Installer replaces Solaris JumpStart and simplifies hands-off installation. AI also supports automatic creation of Solaris Zones.
·       Distro Constructor creates Solaris binary images that can be installed over the network, or copied to physical media.
·       The previous SVR4 (System V Release 4) packaging tools are included in Solaris 11 for installation of non-Solaris software packages.
·       All of this is integrated with ZFS. For example, the alternate boot environemnts (ABEs) created by the Live Upgrade tools are ZFS clones, minimizing the time to create them and the space they occupy.
Network virtualization and resource control features enable networks-in-a-box
Previewed in Solaris 11 Express, the network virtualization and resource control features in Oracle Solaris 11 enable you to create an entire network in a Solaris instance. This can include virtual switches, virtual routers, integrated firewall and load-balancing software, IP tunnels, and more.
In addition to the significant improvements in flexibility compared to a physical network, network performance typically improves. Instead of traversing multiple physical network components (NICs, cables, switches and routers), packet transfers are accomplished by in-memory loads and stores. Packet latency shrinks dramatically, and aggregate bandwidth is no longer limited by NICs, but by memory link bandwidth.
But mimicking a network wasn't enough. The Solaris 11 network resource controls provide the ability to dynamically control the amount of network bandwidth that a particular workload can use.  (Note that some of the details may have changed between the Solaris 11 Express details described in that entry, and the details of Solaris 11.)
Easy, efficient data management
Solaris 11 expands on the award-winning ZFS file system, adding encryption and de-duplication. Multiple encryption algorithms are available and can make use of encryption features included in the CPU, such as the SPARC T3 and T4 CPUs. An in-kernel CIFS server was also added, and the data is stored in a ZFS dataset. Ease-of-use is still a high-priority goal. Enabling CIFS service is as simple as enabling a dataset property.
Improved built-in computer virtualization
Along with ZFS, Oracle Solaris Zones continues to be a core feature set in use at many data centers. (The use of the word "Zones" will be preferred over the use of "Containers" to reduce confusion.) These features are enhanced in Solaris 11. I will detail these enhancements in a future blog entry, but here is a quick summary:
·       Greater flexibility for immutable zones - called "sparse-root zones" in Solaris 10. Multiple options are available in Solaris 11.
·       A zone can be an NFS server!
·       Administration of existing zones can be delegated to users in the global zone
·       Zonestat(1) reports on resource consumption of zones.
·       A P2V "pre-flight" checker verifies that a Solaris 10 or Solaris 11 system is configured correctly for migration (P2V) into a zone on Solaris 11.
·       To simplify the process of creating a zone, by default a zone gets a VNIC that is automatically configured on the most obvious physical NIC. Of course, you can manually configure a plethora of non-default network options.
Advanced protection
Long known as one of the most secure operating systems on the planet, Oracle Solaris 11 continues making advances, including:
·       CPU-speed network encryption means no compromises
·       Secure startup: by default, only the ssh service is enabled - a minimal attack surface reduces risk
·       Restricted root: by default, 'root' is a role, not a user - all actions are logged or audited by username
·       Anti-spoofing properties for data links
·       ...and more.
There are multiple reasons why this important news:

On Oracle OpenWorld 2011 several new Appliances were introduced as well:



ORACLE SPARC SUPERCLUSTER T4-4

The Oracle SPARC SuperCluster T4-4 is the world’s fastest general purpose engineered system that delivers high performance, availability, scalability and security across a wide range of enterprise applications, including database, middleware, Oracle and custom applications.

All hardware and software components are supported by a single vendor—Oracle—and offers customers unique pay-as-you-grow software licensing to quickly scale from 2 processor cores to 24 processor cores without incurring the costs and downtime usually associated with hardware upgrades.




Big Data for the Enterprise

With the recent introduction of Oracle Big Data Appliance, Oracle is the first vendor to offer a
complete and integrated solution to address the full spectrum of enterprise big data requirements.
Oracle’s big data strategy is centered on the idea that you can evolve your current enterprise data
architecture to incorporate big data and deliver business value. By evolving your current
enterprise architecture, you can leverage the proven reliability, flexibility and performance of your
Oracle systems to address your big data requirements.
Defining Big Data

Big data typically refers to the following types of data:

Traditional enterprise data – includes customer information from CRM systems,
transactional ERP data, web store transactions, general ledger data.
• Machine-generated /sensor data – includes Call Detail Records (“CDR”), weblogs,
smart meters, manufacturing sensors, equipment logs (often referred to as digital
exhaust), trading systems data.
• Social data – includes customer feedback streams, micro-blogging sites like Twitter,
social media platforms like Facebook

The McKinsey Global Institute estimates that data volume is growing 40% per year, and will
grow 44x between 2009 and 2020. But while it’s often the most visible parameter, volume of data
is not the only characteristic that matters. In fact, there are four key characteristics that define big
data:

Divided solution spectrum

Many new technologies have emerged to address the IT infrastructure requirements outlined
above. At last count, there were over 120 open source key-value databases for acquiring and
storing big data, with Hadoop emerging as the primary system for organizing big data and
relational databases expanding their reach into less structured data sets to analyze big data. These
new systems have created a divided solutions spectrum comprised of:

• Not Only SQL (NoSQL) solutions: developer-centric specialized systems
• SQL solutions: the world typically equated with the manageability, security and trusted
nature of relational database management systems (RDBMS)

NoSQL systems are designed to capture all data without categorizing and parsing it upon entry
into the system, and therefore the data is highly varied. SQL systems, on the other hand, typically
place data in well-defined structures and impose metadata on the data captured to ensure consistency and validate data types.



Oracle’s Big Data Solutions

Oracle’s big data strategy is centered on the idea that you can
evolve your current enterprise data architecture to incorporate big data and deliver business
value, leveraging the proven reliability, flexibility and performance of your Oracle systems to
address your big Oracle data requirements.
