Why Capacity Planning Is Critical in the Colo Environment Many organizations are opting to move into a co-location facility rather than build out or expand their own data centers. Co-location enables them to preserve capital and move data center expenses to the operational side of the ledger. But moving into a co-lo doesn’t eliminate the need for effective capacity planning. It’s critical to ensure that you’re maximizing the value of the space and power you’re buying from the co- location provider. Co-location facilities sell power in fixed increments often 5KW per rack. If you install gear in the rack that’s drawing only 2.5KW you’re paying for power that you’re not using. That’s known as “stranded power.” If the rack isn’t full you could put more equipment in it and use up more of the power. But if it’s full and you need to move more gear into the co-lo you’re going to have to add another rack. Now you’re paying for more space and another 5KW of power. As your environment grows your co-lo bill becomes much larger than you had planned. How does this happen The reasons vary of course but it often has to do with underutilized equipment. Many organizations have servers that are operating well under capacity. Maybe there’s an application that runs only three hours a day and the server sits more or less idle for the other 21 hours. In an on-premises data center that might not make too much difference. But in a co-location facility that server is taking up space in a rack and you’re paying for power the server isn’t using. Managers of hyperscale data centers know at a granular level how much power each piece of equipment draws. But most IT professionals have only a basic understanding of power requirements. You might think it makes sense to look at the power specifications listed on the faceplates on the equipment and do a little bit of arithmetic. However equipment manufacturers

almost always overstate power requirements so you’ll still end up provisioning more power than you need — particularly if that equipment is underutilized. If you’re planning to move into a co-location facility it pays to do your homework before you sign a multiyear contract. By setting up a testbed in your lab you can monitor how much power the equipment consumes under actual workloads — both at the rack level and ideally at the device level. Monitoring power consumption at the device level is more challenging but it will help you determine the best rack configuration for your co-lo deployment. The same principles apply when deciding to expand your co-lo space. Before buying another power width from the co-lo provider analyze your current utilization levels and determine if there are ways to optimize your existing rack space. Can a server support another virtual machine Can you consolidate or remove devices from the rack Again monitoring power consumption at the device level will help you make more-informed decisions. Rahi Systems has extensive real-world experience in the design and optimization of data center infrastructure. We have an array of software and hardware tools that can analyze power consumption providing our experts with granular data for configuring highly utilized high- density racks. Let us help you plan your co-location capacity so you gain maximum value from your investments.
