Storage Provisioning and Capacity Management
Capacity provisioning is probably one of the largest challenges any storage administrator
faces today. This challenge begins from day one, when the volumes are created and
provisioned. StorTrends iTX, with its Thin-provisioning architecture, takes this headache
out. Once the initial hurdle is crossed, the next big and persistent problem a storage
administrator faces is to take an inventory of what is present
today and predicting how
much of growth is anticipated over the next few months, year or even beyond. Just
current inventory, which most of the storage stacks provide, is simply not enough to help
out. Capacity planning is a very inexact science and it is very time consuming to
administer without the appropriate tools. StorTrends iTX, with its statistically collected
and maintained data along with extrapolation algorithms, provide all that is required to
predict capacity growth and enable strategic capacity planning to a reasonable degree of
accuracy.
Below is a screenshot of storage provisioning and capacity management, showing long-
term and short-term trends.
