As admins seek to streamline data center operations, many are pushing\n for a transition from heterogeneous to homogeneous environments. This \ncan be done as part of any hardware refresh cycle, but the switch still \nrequires planning, and admins need to map out how to migrate workflows \nso no important data is lost in the process.<\/p>\n\n\n\n

Heterogeneous data centers contain hardware from a variety of \ndifferent vendors, while homogeneous — or converged — data centers \nrely on a single vendor’s hardware and often come in the form of a \nconverged .<\/p>\n\n\n\n

There are both pros and cons to transitioning to a converged data \ncenter. The most touted advantage is that basing the data center around a\n single vendor’s products<\/a> often means there is a single point of contact for support.<\/p>\n\n\n\n

Taking the converged data center approach can also improve \noperational efficiency. With a single vendor offering, admins do not \nneed to know all of the nuances of multiple hardware offerings or \nmanagement tools. Instead, the data center hardware is at least \nsemi-uniform and admins can manage it from a common tool.<\/p>\n\n\n\n

It is also possible for an organization to benefit from the economies\n of scale by transitioning to a homogeneous data center. If the \norganization is purchasing all of its hardware from one vendor, \norganizations may also get bulk pricing discounts.<\/p>\n\n\n\n

Of course, homogeneous data centers face the problem of vendor lock-in<\/a>.\n If the entire data center is based on a single vendor’s products, then \nadmins rely on the vendor for security patches, software updates and \nhardware pricing, removing a certain level of management flexibility.<\/p>\n\n\n\n

Another potential disadvantage of using a single vendor is that \nadmins may have to wait for new technology if their vendor of choice is \nslow to market with innovative products.<\/p>\n\n\n\n

Key considerations for a converged data center<\/strong><\/h3>\n\n\n\n

Once an organization commits to the adoption of a converged data \ncenter architecture, admins must focus on preventing data loss during \nthe migration. A complete transition to a homogeneous data center \nencompasses all the data center systems, including those used for backup and recovery<\/a>.\n It makes sense to bring the new backup and recovery systems online \nfirst so that the workloads are immediately protected when they are \ntransitioned to the new architecture.\n \n \n Admins should support premigration data backups as part of the transition.\n \n \n \n <\/p>\n\n\n\n

Admins should support premigration data backups<\/a>\n as part of the transition — at least for a certain period of time. \nThis means allotting time for an extended transition period where both \nthe old and new backup systems remain online. Legacy backups should not \nbe fully retired until they are no longer needed.<\/p>\n\n\n\n

Additionally, the organization needs a plan for how to migrate each \nindividual workload to the new hardware. If the current data center is \nheterogeneous, then there may not be a migration plan for every \nworkload. It will therefore be necessary to come up with a plan that not\n only addresses migration methods for each workload, but also the order in which admins transfer the workflows<\/a>.<\/p>\n\n\n\n

It may be tempting to migrate the most resource-starved or \nmission-critical workloads first, but it actually makes more sense to \nmigrate the least important workloads first. This way, admins can test \ntheir migration techniques and validate post-migration performance \nbefore moving the organization’s most important workloads.<\/p>\n","protected":false},"excerpt":{"rendered":"
