Abstract
This is an important announcement for all customers with IBM® System Storage™ N series storage systems utilizing Fibre Channel–Arbitrated Loop (FC-AL) hard disk drives (HDDs). Fibre Channel 10K RPM HDDs are transitioning to 15K RPM HDDs, and this change will have an impact in customers’ environments.
Content
The 10K RPM FC-AL HDDs are at the end of their availability. As our HDD supply transitions from 10K to 15K RPM HDDs, customers will have limited options for new storage:
For reference, the table below identifies part numbers of the affected HDDs:
As customers integrate 15K RPM HDDs into their environments to add or replace storage, some corner-case issues may arise that may require the customer’s attention. For example:
Recommendations
In order to fully support the transition to 15K RPM HDDs on a customer’s storage system for all currently available capacities, one of the following minimum Data ONTAP releases must be installed:
As a best practice, verify that the latest Disk Qualification Package (DQP) for Data ONTAP is installed on your N series storage systems. Data ONTAP releases and the DQP can be obtained from the IBM Support Portal.
Download/Installation Instructions
Instructions for upgrading HDD firmware are available from the N series support website:
- 144GB (45E2370) HDDs are only available as a 15K RPM option.
- 300GB HDDs are available in both 10K RPM (23R2966) and 15K RPM (45E2371) options.
- After 2008, only 15K RPM HDDs will be offered for new FC-AL storage.
- Customers may receive 15K RPM HDDs as replacements for 10K RPM HDDs.
For reference, the table below identifies part numbers of the affected HDDs:

As customers integrate 15K RPM HDDs into their environments to add or replace storage, some corner-case issues may arise that may require the customer’s attention. For example:
- HDD firmware download capability may not be supported in earlier versions of Data ONTAP.
- Creating new aggregates or adding disks to existing 10K RPM aggregates may generate messages that lead to unnecessary concern.
Recommendations
In order to fully support the transition to 15K RPM HDDs on a customer’s storage system for all currently available capacities, one of the following minimum Data ONTAP releases must be installed:
