Migrating from SUSE Linux to Oracle Linux 5.5 [25325]
Dell Undertakes the Shift on Worldwide Basis

In June 2010, Dell was operating some 1700 servers in various worldwide locations on SuSE Linux when it decided to migrate to Oracle Linux 5.5, leaving the hardware and application layers unchanged. Dell found sufficient capacity on some existing MegaGrid implementations to allow the applications and databases to be migrated to the grid and the SUSE Linux server powered down and decommissioned. Although Oracle does not support heterogeneous Oracle RAC clusters, Dell experienced no issues during the transition with nodes running SUSE Linux interoperating with nodes running Oracle Linux. Dell expects to complete the migration in June 2012.

Illumos User Group Meetup - Menlo Park, Tuesday, January 10, 2012, 7:00 PM [25195]
Live Stream and Playback Available

There is now a Meetup.com group dedicated to Illumos.

The next Meetup event will take place on Jan 10th event at the offices of Delphix. The Meeting Topic is, "ZFS is ten years old!"

A live video stream of the Meetup will be here.

Matt Ahrens of the ZFS Working Group will talk about what's new and what's coming in ZFS, with time for discussion about other topics of interest to the community. Pizza and beer (and soft drinks) will be provided.

For future meetings (after this one) we'll trade locations between Delphix's Menlo Park office and Joyent's San Francisco office, to spread the commute burden. Frequency of meetings TBD.

Illumos is a fully open community project to develop a reliable and scalable operating system. It began as a fork of the former OpenSolaris operating system.

Sponsors of the Illumos project include Joyent, Nexenta, OpenIndiana", box.com and Delphix.

Reasons to Implement iSCSI [25136]
eWeek (November 14, 2011)

"Storage connectivity is evolving away from wires and embracing the Internet ... Fibre Channel ... most often used in large data centers for high-transaction workloads, has been on the market for decades ... Internet Small Computer System Interface (iSCSI) - an end-to-end protocol for transporting storage I/O block data over an IP network - has matured ..."

Setting up a SAN or NAS may or may not be the solution for you data center now that iSCSI has come into the picture. Here are "10 Reasons Why 10Gb iSCSI Connectivity Wins Acceptance in Data Centers". One of the big reasons is that iSCSI is open standards-based and you avoid vendor lock in.

Comparing FCoE to iSCSI [25099]
IT World (December 13, 2011)

"I’ve attended two conferences recently where a speaker talked about storage efficiency and the growing capacity demand problem. The speaker said that a part of the problem is we don’t throw data away. That blunt statement suggests that we should throw data away ..."

While the article is biased towards FCoE there is benefit into learning how FCoE is different that iSCSI. Under the guise of "Converging SAN Traffic In the Data Center", a Cisco solutions architect provides very good insight into how FCoE solves business problems associated with SANs and iSCSI. Just remember that no one technology is the panacea for all data storage, access and backup issues.
