"There are many interdependent relationships within data centers, and everyone in the organization needs to rely on them to do their work effectively."John Heinlein, an IT director at livingston county, mich., community mental health management, said he led a team that completed the migration in May."This is not something that people can solve in a busy afternoon," he said. "it requires a lot of planning, patience and cooperation."
"There's no reason for organizations not to respond," says Dominic Rozzo, a network and systems administrator at Canfield.
1. The new livingston county data center is upgraded
For livingston county community mental health officials, the decision to move their equipment to a larger data center facility a mile away was a smart one.The original data center did not install the backup generator, but used some UPS power equipment to keep IT running during the temporary power failure.Typically, a power outage can damage these backup power sources, Heinlein said, adding that it takes extra time to test the migration server and make sure everything is running properly.
"The real impetus for this is to make people realize that in a data centre facility with generators and more reliable power, the better the equipment, the better for the end user," Heinlein said.Heinlein and livingston county community mental health officials decided to the agency's most virtualization but outdated server and a separate storage area network integrated into Nutanix single super convergence in the solution provided by the company.
"Instead of two servers and a storage array that takes up about six rack space units, we can do all the work in two rack Spaces," Heinlein said.He explains that most of its 175 end users rely on Citrix's thin client to access files and applications.
Recognizing the difficulties of migration, Heinlein began planning reforms a year before the migration of data centers.Livingston county community mental health bureau IT department engineer to evaluate the new data center facilities infrastructure requirements, including the use of a new cisco systems components update core data center network, in the new facilities installing new APC rack and UPS provided by the company, and update existing VMware vSphere software.Finally, engineers at Nutanix began integrating traditional devices into new hyperfusion solutions, and engineers at livingston county's community mental health service helped set up the server migration.
Heinlein also works with each end-user device to make the necessary network changes and to coordinate periodic switching with AT&T.After all these preparations have been made.The actual migration takes only 24 hours, and from then on, all the equipment and businesses will be running efficiently.
"The better prepared you are, the more load you can pre-load, the better people can anticipate and adapt to challenges, and everything will be better," he says.This applies to information technology, and it's like building a house.
2. The data center of Canfield company was successfully migrated
At Canfield, Rozzo faces the daunting challenge of moving existing data centers from within local police departments to new machine rooms in the same building.But given the crowded conditions of the original data centre, its departments accepted the change.
He said, "the original data center run by the city of two servers, the entire infrastructure basic deployment in a mixed in other wiring chaotic electrical cabinet, cabinet of devices almost unable to move, not to mention some additional equipment.This is crazy.Rozzo and his team work directly with the architects and builders of the new machine room to meet their specific technical needs.
A movable floor with drain pipes is installed in the machine room and all walls and ceilings are reinforced with steel.And it will have comfortable working Spaces that will expand over time.
The IT team to create a backup plan, design the network plan, in order to minimize downtime, determine the cooling demand, in order to ensure persistent connections with the original data center, the original data center and exchange between the new data center configuration, and coordinated with the time of users and other services.
Rozzo says color coding and labeling can speed up the process.The blue cable represents the data line, the white cable represents the telephone line, and the blue cable represents the optical fiber.
"Workers just look at it and know what each wire is and minimize troubleshooting.""When there are so many things going on, there will be huge changes in efficiency and confidence through effective measures," he said.Rozzo pre-configured some Cisco 3850 switches and ensured that all network and backup plans were in place, helping him and non-it professionals switch and migrate within 24 hours.Despite careful preparation, the telephone servers in the local police department's dispatch system were mysteriously cut off.With a backup plan, Rozzo quickly switches lines and minimizes downtime.
"It shows how critical it is to spend time on things that are careful and right," he said.
Oklahoma provides better service through integration and upgrading
Migration and upgrade the move to data center has become the Oklahoma state management and corporate services office (OMES) in normal operation, the office in 2011 began a long process, will be incorporated into the individual institutions operating center Oklahoma, a Tier of level III data center.
It is the most complicated task: migration has been old, the U.S. department of health and human services (DHS), the massive data center, the data center covers an area of 8222 square feet, operates the 55 highly critical systems.
In 2016, months before a memorial day, Oklahoma, chief information officer James Bo "Reese and his team with the United States department of health and human services (DHS) in the IT team to work with business users, in order to effectively prepare for the environment.They eliminated the original server, using VMware virtualization some physical servers, and through transferring them to HP 3 par StoreServ 7400 thin provisioning storage/BLc7000 server blade chassis (collectively referred to as Zeus system), to further virtualization much critical systems.So they coordinated the transition to the end.Their efforts also include preparing test plans to make sure the system works when everyone is back on the job.
"When we started restarts, the U.S. department of health and human services (DHS) user and we work together, they can log in to their system, and immediately started by their test plans, identify and record any problems."Reese said.
The partnership and patience paid off.The teams completed their tasks on time without any interruption.And, more importantly, the U.S. department of health and human services (DHS) system is now in Oklahoma, management and corporate services office (OMES) data center need to deploy the seven frame of only 100 square feet of space, a 810% reduction in demand.
"Every step of migration in a data center is stressful and nerve-racking because these systems affect the work and life of citizens every day.""So we're very happy because everything is so successful," Reese said.
Florida's FAST is rolling out an overall upgrade
In the second half of 2015, officials at the Florida state department of technology (FAST) plan to better merge the two data centers into one by 2019.When old facilities in the two data centers failed, officials were instructed to integrate within 120 days.The plan calls for the integration of these facilities as soon as possible.
Florida state technology (FAST) state, executive director and chief information officer Eric Larson said, "in the implementation of the plan we had some confusion, so I don't know how to take action within the framework of this time."
The challenge is huge.The combined data center deploys more than 2,000 servers to 12 government agencies in the state, including the U.S. department of children and families and the U.S. department of environmental protection.The team had to dismantle, purify and reassemble the servers and other equipment in the data centers.
However, shorter schedules ultimately prove to be a benefit of end-user collaboration.Agency heads' departments collaborate to ensure that a holistic, high-priority approach is provided.
"Everybody realizes this is an extraordinary situation."Larson says.He points out that organizations can choose to pre-virtualize their servers and migrate to new data centers or physical migration by truck.
Virtualization has played a vital role in accelerating this move.Because they now plan to merge the two businesses, the team at the Florida state department of technology (FAST) has built a data interconnection between the two data centers and provided a lot of bandwidth."This allows us to not only migrate the virtual workload between the two sites, but also to migrate the application server or database to the target facility.In that case, any dependency will depend on this interconnection.Larson says.
Still, the Florida state department of technology (FAST) eventually moved the workload to the new data center and then moved the old equipment out of the old data center before moving more.
"We suggest that this will add more capacity to the new data center in the next migration event."Larson says the process allows his team and other IT people to count and identify more than 300 servers that need to be eliminated.
The plan and process was better than expected, and the team at the Florida state department of technology managed to clean up and move the data center within 100 days, three weeks ahead of schedule.
