IBM Adapter for NVMe1.1 and IDAA Internal Storage

Edit online

The IBM® Adapter for NVMe (Non-Volatile Memory Express) feature utilizes NVMe to provide 9176 fast access to data stored on Solid State Drives (SSDs). NVM Express is an open collection of standards and information to fully expose the benefits of non-volatile memory in all types of computing environments from mobile to data center. NVMe™ is designed from the ground up to deliver high bandwidth and low latency storage access for current and future NVMe technologies.

IBM Adapter for NVMe details:

  • Available with both IBM z17 Single Frame (Model ME2) and IBM LinuxONE Rockhopper 5 Single Frame (Model ML2)
  • A zero port, single PCHID adapter card
  • Order the adapter in increments of 1 feature, with maximum of 16 features
    • You can order the IBM Adapter for NVMe1.1 (FC 0448).
    • You can order the IDAA Internal Storage (15TB) (FC 0528).

IBM provides the adapter card into which a vendor NVMe SSD can be plugged. The NVMe SSD is customer supplied and installed into the IBM adapter card by the IBM service representative.

Important:

Once installed, any future servicing of the customer supplied NVMe SSD requires a service contract to be in place. The servicing or replacement of the NVMe SSD by an IBM Service Representative is not covered under Warranty or Maintenance Agreement.

Attention: The selection and purchase of the SSDs in this feature are the responsibility of the customer. The IBM LinuxONE NVMe white paper (https://www.ibm.com/downloads/cas/QK53QV0E) lists the performance of SSDs that IBM has tested for LinuxONE. IBM can only comment on the functionality of the SSDs that have been tested. The customer assumes all risk in, and IBM is not responsible for, the use of SSDs as the functionality or performance may vary.
