Implementing a capacity management plan is largely regarded as the solution to adopt to keep storage costs under control while ensuring a high level of services. Unfortunately, when times come to follow this best practice, things naturally get more complicated. But as complex as it may seem at first sight, adopting capacity planning can be pretty easy if keeping just a few tips in mind. Let’s review them in this post.


Tip 1: Determine Current Use

Generating capacity plans under incomplete knowledge or false assumptions inevitably leads to approximate or unrealistic scenarios. As strange as this may sound, this situation is sadly common. This is even more surprising when powerful capacity management tools, such as TrueSight Capacity Optimization, are available and provide an accurate state of the SAN infrastructure. Among many valuable information, TrueSight Capacity Optimization for Storage indicates how much resource is currently used, how much capacity is being unused or underutilized, and if there is enough capacity to cope with unexpected storage demands. With that information close at hand, it is easier to determine whether the SAN infrastructure is adequate for today’s needs.


Tip 2: Determine Future Requirements


Today’s needs may be met but this does not guarantee that tomorrow’s will be. To ensure that administrators are in line with business planning cycles, they can collect workload forecasts and planning information from users and translate them into IT resource requirements. This first step will allow administrators to predict what resources are to be implemented to answer business needs.




Tip 3: Evaluate Potential Growth


Before setting up short-term or long-term plans, administrators need to know the growth rate they have experienced over the last year. Without capacity planning tools, they will have to verify the number of additional storage and server ports added to determine the growth rate percentage. With BMC TrueSight Capacity Optimization, they just have to look at the trendlines generated from past and current resource utilization to plan for future capacity needs.





Tip 4: Evaluate Alternatives

Purchasing additional storage is too often the first choice made to ensure the SAN infrastructure can cope with unexpected demands. But this is not the only option! Other alternatives exist at a more reasonable cost. Implementing deduplication, efficiently and cost-effectively using SSDs and HDDs are common methods. But few knows that they can also better manage thin provisioning and reclaim unused capacity with TrueSight Capacity Optimization. This powerful solution helps increase the storage efficiency ratio by keeping just the minimum space available to meet current and future storage allocation requirements. Thanks to TrueSight Capacity Optimization for Storage, administrators can also identify mapped and unmapped volumes for which no activity has been recorded for a long time and that can therefore be safely reclaimed. Purchases are logically postponed and savings increased.



Tip 5: Plan for Expansion

No matter how hard administrators work to postpone purchases, there will always be a time when they will be running out of capacity. Their everyday challenge is therefore to predict when this situation will occur. Thanks to BMC TrueSight Capacity Optimization for Storage, administrators can identify possible risks of saturation and oversubscription to prevent data loss and corruption.


They can also verify if there are enough disks in their storage systems to extend the capacity of their storage pools. With the Available Capacity for Storage Pools metric, they will even be able to know how much capacity is not consumed in all storage pools.

Capacity Planning Is Pretty Easy, Isn’t It?

As you can see capacity planning can be pretty easy if relying on powerful capacity management tools like TrueSight Capacity Optimization!
