15k RPM or 10kRPM - is just one of the questions!

Understanding Disk Subsystem performance becomes more complex every year. Storage Managers have to take into consideration many technologies to gain a thorough understanding of current performance.

Today, Storage Specialists have to take into consideration technologies such as high capacity physical disks, high capacity logical volumes, RAID schemes, Fibre Channels, Synchronous and
Asynchronous Copy Services solutions, cache size options, Parallel Access Volumes, and many more.

Disk Magic can help. It provides you with a thorough understanding of your current Disk Subsystem performance and enables you to make better purchase and configuration decisions.

Disk Magic shows current and expected response times, utilisation levels and throughput limits for your own installation’s I/O load and server configuration.

When you plan for an upgrade, Disk Magic enables you to select the most cost-effective configuration options with confidence. You can model changes to the disk drive technology, the cache size, the number of Fibre or FICON channels, and more.

Your organisation can use Disk Magic to answer the following questions:

• What will be the performance impact of moving from 73 GB to 146 GB disk drives?
• Which component will need upgrading first at a 30% annual growth percentage?
• What is the current utilisation level of Processors, Channels, Host Adapters & RAID ranks?
• Should we invest in 15k RPM disk drives, or whether 10k RPM disk drives will suffice
• Compare bandwidth requirements and response time impact of the various Copy Services
  solutions in your environment
• Chart current and predicted response times when considering the move of a specific iSeries
  ASP to another disk type
• Show what the result would be of consolidating four ESS F20s to one DS8300
• Analyse whether your most critical application would run better on RAID 10 than on RAID 5
• Predict the performance benefit that will be gained from increasing the cache size
