School of Global Management Improves Efficiency While Expanding Its Business

NetApp (NASDAQ: NTAP) has announced it has helped the Thunderbird School of Global Management reduce hardware and administrative costs for its IT network while expanding services for the school's students. By implementing NetApp® MetroCluster and Ethernet storage solutions, Thunderbird has been able to take its business global while maximizing availability and minimizing costs.

Prior to adopting NetApp technology, Thunderbird was trying to expand its courses and degree programs and move them online for a wider audience. This meant also expanding IT capabilities from supporting local students to supporting students around the globe, who would need access around the clock. Thunderbird worked with regional systems integrator Trace3 to develop a solution based on NetApp technology to take the school's programs global.

Thunderbird first upgraded its network backbone to 10 Gigabit Ethernet, which dramatically increased speed and reliability. NetApp 10 Gigabit multiprotocol Ethernet storage was flexible enough to support Thunderbird's NFS with Linux® and UNIX® servers, CIFS for Windows® desktops, and iSCSI for database applications. The ease of sharing and reusing the NetApp storage was a big benefit, as well as supporting different requirements with one storage system. NetApp Ethernet storage also had the benefit of being less costly than the alternative solutions the school looked at.

As Thunderbird's online business succeeded, the school moved to a clustered storage model based on NetApp MetroCluster and VMware® to continue to grow the school's business and improve availability. With MetroCluster running on two FAS3050 systems, Thunderbird has had continuous availability since the moment the system was turned on, even in the event of hardware failures. The school has also taken advantage of MetroCluster's integration with VMware ESXi to provide a completely available environment while reducing server and storage equipment in the data center by approximately 40%. Thunderbird has also saved in power, cooling, and operational costs due to reduced hardware and MetroCluster's automation and administration simplicity.

EMC Corporation (NYSE: EMC) has announced enhanced enterprise backup capabilities for desktop and laptop computers, as part of the latest version of EMC® Avamar® software. Businesses and organizations of all sizes can now leverage the same innovative Avamar deduplication technology that protects data centers and remote offices to efficiently backup the information stored on corporate desktops and laptops. With Avamar's simple capacity-based licensing model, customers can easily add this new capability to their environment, without paying a per seat license fee.

The addition of new lightweight clients for Microsoft Windows and Mac, an intuitive end user interface for backups and restores, and powerful tools for administrators, Avamar extends Avamar's enterprise data protection to desktops and laptops. Using Avamar means backups are non-disruptive, and a self-service recovery model makes it easy for end users to restore data. Avamar users never have to backup the same data twice, reducing daily network impact by up to 99%.

EMC has increased Avamar backup capacity by more than 60 percent and added new deduplicated export to tape functionality.

• Added Backup Capacity – The next-generation of the Avamar Data Store delivers more than 60 percent more capacity in the same footprint, and offers build-to-order solutions for reduced deployment time and cost. The Avamar Data Store Gen3 is available in 1 to 16 storage node configurations, with up to 3.3TB of capacity per node, for scalability up to 52.8TB of deduplicated capacity in a single grid.
• New Avamar Data Transport for Long Term Storage – This capability enables the export of deduplicated data to tape for cost-effective long-term storage, helping to reduce tape storage by up to 50 times. Through policy-driven processes, customers can easily export deduplicated data to tape and leverage searchable file-level catalogs for rapid restores.

EMC Avamar, version 5.0, is available immediately from EMC and its Velocity² and authorized partners.

Sometimes we have to do shutdown / restart the database in a cluster environment, there are several ways that make us not so sure. Or even if not careful will lead to a more complex problem again.

Here are steps to restart / shutdown the database in a cluster environment:

Freezing Veritas Cluster-group service to existing group:
#haconf -makerw
#hagrp -freeze Oracle-ClusterName
#hagrp -freeze cvm
#hagrp -freeze vtape
#haconf –dump -makero

See whether the service group status was the Freeze
#hastatus –sum |grep G

(Restart / shutdown Oracle DB, or other actions)

To unfreeze Veritas Cluster-group service to existing group:
#haconf -makerw
#hagrp -unfreeze Oracle-ClusterName
#hagrp -unfreeze cvm
#hagrp -unfreeze vtape
#haconf –dump -makero
