Re: More P9 SSD disk drive questions

If by 4xx you mean 4K Drives that is not true. They cannot be mixed in the same RAID set but can be in the same drawer.

They are clearly producing no new 5xx drives though existing models are still being sold.

The EXP24X drawer is for very large capacity 3.5" form factor (LFF) 7200 ROM 'near line' drives. Thee would not be used for traditional IBM i workloads but could archive a LOT of stuff!!

Yes currently the flash adapter is for Linux AIX or VIOS. They don't currently make sense for IBM i in the current configuration.

I read this somewhere, but not finding it?
I was planning on keeping and using my old 5XX SSD, placing them in ASP02 for R&D.
Still can done, be this will require their own EXP24X drawer, cannot be mixed with 4K in the same drawer, correct?

2) The below is a bit confusing?
It "appears" the 5XX drives are a thing of the past.

The 3.5-inch large form factor (LFF) SAS HDDs are supported in the EXP24SX. All
drives are mounted on Gen1 carriers/trays and thus named LFF-1 drives. Only 4k
byte sector drives are supported in the EXP24SX drawer. The 5xx byte sector drives
are not announced or planned. Drives are 7200 rpm and sometimes referred to as
nearline. These drives provide excellent cost per gigabyte. Note that formatting
or rebuilding arrays on large disk drives can take hours. If higher performance is
required, consider higher rpm disks or SSDs in the EXP24SX drawer.

3) Anyone planning/thinking of using the PCIe3 NVMe Flash Adapter?
I think this is for Linux only though?
Do you think we'll see this for the I in the future?

Support for the PCIe3 NVMe Flash Adapter (1.6 TB (#EC54/#EC55 and 3.2 TB #EC56/#EC57) is expanded. PCIe NVMe Flash Adapters can offer significant improvements in write latency and I/O throughput compared to using SAS-attached SSDs or FC-attached SSDs in SANs or FlashSystems for Linux applications using the high-performance NVMe interface protocol; for example, using the NVMe Flash Adapter for Rapid Restart of SAP HANA. The speed of the NVMe Flash Adapter helps the partition load more quickly, improving up-time of the application. These enhancements are announced:

* Boot drive support is added.
* Support is added for the Power E850 and E850C servers, joining existing support on many other POWER8 servers, including recently announced Power E870C and E880C servers running in a Linux environment.
* The Power S812L, S822L, and S824L systems now support Power NV mode, also known as bare metal.
