What is the right approach to setting data management policies? The first step
is to understand that there is a really a hierarchy of policies within the
organization and all must be in place to manage data effectively. At the top
are strategic policies. These are the laws of the organization that define at a
high level the manner in which data will be managed, protected, and retained.
Strategic policies provide the foundation for governance and oversight and tend
to be statements of direction. These policies are established by senior
management within the organization or specifically designated functional units
tasked with an area such as regulatory compliance. A rule that storage will be
provided under a service provider model with service level agreements and known
costs is an example of a strategic policy.
Tactical policies support the achievement of strategic policies and focus on
particular functional groups like storage. These policies address areas
relating to accountability and execution of functions including provisioning,
change management, data protection and security. Policies relating to who,
where, and when to classify, archive, and purge data on a periodic basis
represent tactical policies. The problem is that the required strategic and
tactical policies are often lacking. The result is the misalignment that we
hear so much about between business and IT.
Operational policies are the rules that govern specific procedures. The actual
activities related to moving data to an archive and purging would be governed
by these policies. Sending tapes offsite on a daily basis, and multi-pathing
hosts in a fabric are also examples of operational policy areas.
Users forced to be energy-conscious
By John Webster, Computerworld (US online)
News item in local paper: Big New England electric utility seeks rate increase
of 13.1 percent. The reasons, unfortunately, are many, according to the report.
They include rate increases from outside suppliers, wholesale price increases
for natural gas and federal government policy that somehow encourages
investment in new power plants.
Server vendors have been leading the way recently with energy-efficiency
messages. Now were about to see storage vendors join the chorus. Storage
administrators, if they arent already, will become very conscious of the
electricity consumed and heat generated by legions of spinning disks because
storage vendors will make it a competitive issue.
How Back to the Future-ish this all is. Earlier this year, I witnessed a
demonstration of one server vendors approach to cooling rack em, stack em
bladed server farms. Killer fans (seriously). These fans generated
hurricane-force wind. There were only two problems that I could see: First, all
the fans did was send the heat somewhere else for some other piece of equipment
to deal with, like a chiller, and second, the vendor would have to ship a set
of noise-canceling headphones with every box. Guys, havent we been here
before? I seem to remember that water cooling was once thought to be a saner
way to do this.
While I dont think well see water-cooled disk farms any time soon, we will
see storage vendors getting very kilowatt/hour-conscious. Not only will they
talk about the physics of the issue; they also may suggest ways to reduce the
number of I/Os going to spinning disk assuming that doing so will have a
significant effect on power consumption. Thats an interesting approach that,
oddly enough, might cut both ways in that one way to reduce disk I/Os would be
to send them someone elses solid state disk or power-managed disk.
Suggestion for storage administrators: For help with energy management, search
the archives for papers written by past IT administrators on this subject.
Start with organizations like the Computer Measurement Group and AFCOM, and go
back at least 10 years.
Shark Tank
By Sharky, Computerworld (US)
The old ways IT manager in charge of a data warehouse project issues a
directive: Before the warehouse is populated, sales information must be
cleansed and customers coded according to customer type and whether they have
leased or purchased equipment. But the CFO nixes that. "She told us that
cleansing the data was a waste of time, since it would just get dirty again,"
reports a pilot fish on the scene. "And coding customers by type of sale should
always include the customers full name." Why? "When she was a programmer 20
years ago, this was the normal method, and she sees no reason to change the
process now."
A great idea
This office is installing emergency lighting the kind that plugs into a wall
outlet and comes on automatically when the power fails. "My boss had the bright
idea, Lets plug them into one of the UPSs so theyll last longer," says a
pilot fish on the project. "He had the duh! moment a few seconds later, after I
walked him through the why and how these lights come on. Then I mentioned the
UPS idea to our young Web guru. He also thought it would be a bad idea because
it would drain the UPS faster."
I hear voices
Office manager calls pilot fish to complain that she hears voices over the
newly installed wireless network. Fish knows thats impossible, so he just
power-cycles the access point and tells her to call if it happens again. "Two
hours later, she called," says fish. "Sure enough, in her office I heard a
voice say, Switching is complete, we can roll." I looked out and saw a train
next to the building. The rail crews radio was being picked up by the cheap
speakers on her PC."
