When upgrading your NetApp filer it is essential to take growth, performance, and workload into account. If you’re considering a capacity upgrade (rather than upgrading to a new filer altogether), then adding a disk shelf is a cost-effective way to do that.
After deciding on a capacity upgrade, make sure you do your homework to get the best disk shelf for your NetApp filer.
But what makes one disk shelf better than another? It will depend on what the disk shelf is being used for and the applications hosted on that shelf. Are you purchasing this disk shelf because you need high performance for one of your applications?
Then adding a SSD shelf may work better for you than a SATA shelf. If you are hosting a database or large files that you don’t need to access frequently, then a SATA shelf configuration would work best.
For example, the DS4243 is extremely popular because it’s compatible with every current NetApp filer model. It also supports multiple drive types including SSD, SAS, and SATA, allowing you to use the disk shelf for anything from high capacity to performance density.
Understanding Your Data Center Needs
A great deal of mistakes made when it comes to storage infrastructure can be attributed to human error or simply not knowing the best way to use your equipment. Adding capacity to your NetApp filer is no exception.
Understanding best practices when implementing your NetApp storage solution puts you in a better position to make decisions. In this case, the best practice is to keep the same drive types and speed in each disk shelf. For example, adding 10K SAS drives to a shelf that already has 15K SAS drives would cause your performance to suffer.
Instead, if you need a disk shelf to hold a different drive type, a better alternative would be to create a new aggregate. If you decide your new shelf will be dedicated to large-scale data backups, then an all SATA disk shelf like the DS4486 will probably be your best bet as it maximizes capacity.
