Data grows faster than IT budget. It is not the production data that grows so fast, but rather the data copies that support the production.
Along with the capital cost of usable capacity, the operational costs increase. Power consumption, floor space and human capital are all part of the costs of owning and managing a storage system.
Costs are also measured by putting a price tag on how lengthy is the task of provisioning capacity or creating snapshots; how many storage administrators are needed; what percentage of the administration tasks can be automated; what is the cost of human mistake; are we safe from downtime; and so on.
Infinidat offers a new paradigm in the storage – a paradigm that breaks the traditional connection between storage capacity and the cost associated with it.
The challenges at hand
The ever-increasing demand for capacity arises from various aspects of the organization's needs.
- Backup - Local backup copies allow for recovering from data loss and logical data corruption while remote backup copies are used for disaster recovery, audit and regulatory compliance.
- Provisioning - Most organizations provision capacity in thick format. That is, the storage space is purchased and allocated prior to the actual use. Organizations that have already moved to thin provisioning (assessing the actual storage needs prior to purchasing it) find themselves in an increasing risk of downtime, resulting from a lack of tools for capacity planning.
- Data copies - Full copies of the production data consume lots of expensive storage capacity, as well as computational resources that are required for moving them around.
The fast data growth caused by virtualization, increased use of BI and other data-intensive applications has turned storage into the biggest IT spending (around 25% according to studies).
- RAID - Most companies use RAID-1 or 5 for protecting their production data from a single failure for their critical data. And RAID-6 for large drives to provide protection against most dual failures but avoid using it for critical, due to its performance penalty.
- SAS drives - High-performance drives are expensive, and provide smaller capacities. A combination of SATA drives and flash-based SSD drives is both inexpensive and high in performance. However, this combination's efficiency depends on the chosen RAID layout and their ability to manage which data needs to be in which storage tier (pre-fetching).
- Data center - The bigger the data center, the bigger the power and cooling costs, as well as the cost of floor space. The latter costs have skyrocketed in recent years.
