The 6 IT Capacity Planning Essentials

  1. 1. For more information, contact uptime software inc. at:+1.416.868.0152 |© uptime software inc.TheCapacityConundrum…Ensuring the performance and availability of IT Servicesand applications is essential for high performing ITdepartments. At the end of the day, companies cannotrun without the IT infrastructure they depend on andthis makes Data Center Infrastructure Management(DCIM) essential for CIOs, Capacity Planners, ITManagers and Administrators alike. Forrester Researchrecently published a report that projects DCIM tools togrow by 60% through 2014. Why? Data Center capacity limitations are impactingservice delivery growth; Businesses are increasingly reliant on theircritical IT systems; Enterprises have complex heterogeneousinfrastructures with both physical and virtualsystems; Data center consolidation and virtualization isstill accelerating; Increased capacity costs are problematic; Enterprises are experimenting with Cloud IaaS.Success/failure rate is 50/50.There are many DCIM vendors on the market today,and they all seem to be preaching the same mantra ofhelping you “increase IT service performance.” Theproblem with all the noise in the market is that itbecomes difficult for customers to figure out whichsolutions meets their current and future needs.SolvetheBigProblemsFirst…To solve the big problems, IT Managementneeds to focus on capacity. Why? Becausecapacity can be your company’s gold mineor its Titanic.Most enterprises already have plenty of availablecapacity, yet continue to spend IT budget for more.Why? Simply because CIOs and capacity plannerscannot get the critical capacity information they needacross mixed vendor environments, includingmultiple platforms and multiple datacenters. Mostenterprises still have many servers running at 20%capacity or VMs running at 10%. This is a gross wasteof budget and resources, when it should really bemoney in the bank.Enterprises desperately need a capacitysolution that provides complete capacityvisibility, as a majority of CIOs don’t knowtheir current global capacity.The real return for CIOs comes with effective capacityplanning. Capacity planners could be the most unsungheroes of IT. With continually constrained budgets andever more IT services to deliver, CIOs need more bangfor their buck, including additional compute cycles,more I/O to the discs, and heavier traffic on theirnetworks. To make this happen, CIOs and capacityplanners must: Get accurate and granular capacity insight rightdown to the bare metal and service/applicationacross the entire IT stack, with useable reports. Find underutilized capacity and put it back towork in the business. Slow down CapEx on new equipment untilexisting servers are operating at over 60% andVMs are at a minimum of 90%. Understand how moving applications to virtualclusters can deliver increased capacity andefficiency. Get a dashboard and reporting system that canmonitor, measure and report on globalcapacity, ensuring it’s always efficientlyallocated.If CIOs and capacity planners tackle these key areas,they can ensure that data center capacity is enablingthe right amount of IT services to the business at thebest cost.Gartner terms this process Intelligent Capacity Planning(ICP) *DCIM: Going Beyond IT, Gartner Research,THE 6 CAPACITY PLANNING ESSENTIALSBY ALEX BEWLEY, CTO, UPTIME SOFTWARE

ICP makes collecting and analyzinghistorical and real-time data from heterogeneousinfrastructures possible, giving data center managers acommon repository of information on resourceutilization and performance. With the right tool, datacenter managers can optimize the performance,reliability and efficiency of the entire data centerinfrastructure. For any CIO or IT department with bothphysical and virtual infrastructure in a highly dynamicenvironment, this is going to mean the differencebetween the business viewing IT as a cost center andthe business viewing IT as a strategic business weapon.TheTop6CapacityEssentials…1. Trust The Capacity Data Where to start? Stepone is having accurate capacity data. Goodcapacity planning and utilization decisions aredriven, first and foremost, by having good data. Ifcapacity data is unreliable or inconsistent, theintegrity of your decision is compromised. In otherwords: garbage in, garbage out. Rock-solid datacollection is essential. You cannot afford to havesporadic metrics and data collection. Once youhave accurate data, capacity can be better alignedwith business demand.2. Proactive Capacity Trending: Capacity modelingis expensive and not alwaysnecessary. However, a clear pictureof how capacity is trending isessential. It’s important to see howcapacity is trending over time and what theprojected capacity needs are month to month(sliced easily across one or multiple platforms orone or multiple datacenters).3. Proactive Capacity Alerting. IT operations mustbecome aware of capacity problems before theysnowball into a complete server or applicationfailure. Capacity tools must include an alertingcomponent that is as proactive as possible.4. Locate the Capacity Problem Source.Understanding the problem location within themaze of components becomes a key feature thatwill expedite this very critical stage. This is wheremost time is wasted in capacity problemmanagement, with dire consequences for usersatisfaction and productivity.5. Analyze the Root Cause of the CapacityProblem. A capacity management solution mustprovide a way to analyze the capacity issue for theroot cause in the context of the initial alert. Itmust provide the specialist with the ability toperform a “deep dive” into the data, with granularmetrics to better understand the issue, andpropose a problem resolution.6. Have a Capacity and Performance DataWarehouse: Choose a solution that providescomplete collection of all capacity andperformance metrics, giving your ITteam the ability to both predict futurecapacity problems with trendingfeatures as well as ‘time travel’ back in time toperform deep dive forensics on capacity whenproblems do arise.Aboutuptimesoftware:uptime software inc. is the maker of up.time, thecomplete IT dashboard for watching over servers,applications, networks and IT services, with powerful,affordable and easy-to-use monitoring, alerting andreporting for unified performance, availability andcapacity management across the enterprise datacenter.Over 120,000 IT professionals and managers in mid-enterprise and enterprise companies across 40countries have downloaded up.time to increase ITperformance while consistently saving IT staff time andbudget.
