What the ENZ0 drawer is
The ENZ0 is the PCIe4 expansion drawer IBM documents for the Spyre Accelerator on Power 11. The cards live in the drawer, and the drawer attaches to the server. If you are pricing Spyre, you are pricing the drawer too.
When you need an ENZ0 drawer and when you do not
Drawer or no drawer
| AI hardware | ENZ0 drawer needed |
|---|---|
| Spyre Accelerator cards | Yes, in the machine and card combinations IBM lists |
| On-chip Matrix Math Acceleration | No, it is inside the processor |
Four things to confirm before you ask for a Spyre quote
The checklist IBM's drawer documentation implies
- Exact machine typeThe server model, not just Power 11.
- Feature codesThe drawer and card codes IBM lists for that machine.
- Supported Red Hat environmentThe Linux and Red Hat setup that will drive the cards.
- Resource floorThe minimum memory, cores and storage the partition must have.
