Boeing subsidiary solves its storage problems

New EMC setup addresses slow Lotus Notes backups and disaster recovery needs

When the lease was up on its old storage equipment and it came time to consider a new platform, Aviall Services knew exactly what it needed.

The Dallas-based Boeing subsidiary and provider of after-market supply-chain management services for the aerospace, defense and marine industries had been stretching its EMC-based storage setup to the limit.

Not only were backups for its ERP and Lotus Notes messaging systems stretching far beyond their allocated windows, but restorations were so time-consuming, testing showed they would cost the firm thousands of dollars in lost time and productivity.

Russell Douglas, director of customer and supplier services information systems at the company, spoke about his storage experiences at the recent Network World IT Roadmap Conference and Expo in Dallas and in a follow-up interview.

"Our biggest problem was Lotus Notes," Douglas says. "It was taking approximately 24 hours to back up, so by the time one finished, another would begin, and our backups were always failing. With [the Sarbanes-Oxley Act], full backups have to be logged. When they fail, you have to log the reasons why, and they were failing all the time."

SOX also requires that Aviall test the restoration of critical systems every six months. "At the time, a restore of our ERP took nine hours," Douglas says, noting that full restorations were done via backup tapes. "Aviall is a 24/7 business, so you can imagine if we ever had to roll back an entire day's outage. That would cost us hundreds of thousands of dollars."

Aviall was hoping a new storage platform would not only free up more storage space and reduce critical backup and restoration times, but also position the firm to handle future virtualization and real-time disaster recovery needs.

"The [disaster-recovery] portion was primarily a push by Boeing, because if we're going to integrate with Boeing in defense and commercial aviation services, then we have to make sure we have a disaster-recovery plan that can bring us back up literally in a few hours," Douglas says.

Storage scorecard

The company hired a third-party consultant to build an RFP and gather relevant data from top-tier storage vendors, including EMC, Hitachi and Veritas (now owned by Symantec). The consultant, together with Aviall, also put together a weighted scorecard so Aviall's IT staff could assess vendors' offerings, including how each would fit with the firm's existing infrastructure.

The criteria studied included not only technical details -- the features and functions of a specific array; the backup solution; and the ability to support multiple tiers, virtualization, bare-metal recovery, tape backup and hierarchical storage management -- but also the vendor's overall financial outlook and technical road map.

Aviall then formed a committee of IT staff charged with using the new storage platform to make the final decision. At the time, the company's operations department was split, with one side managing databases and Unix servers, both AIX and Sun, and the other side responsible for managing SQL Server and a variety of NT and Novell servers. An equal number of staff from each team filled out the scorecards and had to defend their decisions to Douglas.

"That worked out, because really, they're the ones who have to live with the decision," Douglas says.

In the end, Aviall chose to go once again with EMC, upgrading to its Symmetrix DMX array. The company has never looked back. ERP backups that used to take five or six hours now take just one hour. And the nine-hour ERP restoration has been reduced to 1.5 hours. Similarly, Lotus Notes backups now take just a couple of hours, and have yet to fail.

"The old backups went from the database to tape, but now we go from disk to disk to tape," Douglas explains. "There is no tape contention. We go straight to disk, and then it rolls to tape in the background. That's a primary reason performance is so much better."

It really doesn’t get more “gaming laptop” than this.

Jack Jeffries


As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.

The MSI PS63 is an amazing laptop and I would definitely consider buying one in the future.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.
