Comparing the new Power9 9009-41G vs the 9009-41A

Comparing the new Power9 9009-41G vs the 9009-41A
What's the difference between the new IBM S914 9009-41G and 9009-41A Power9 models? The only difference is the newer 9009-41G S914 model was built entirely with fourth generation PCIe technology, capable of delivering much better I/O performance, bandwidth and faster data transfers. The number of Gen4 PCIe slots vary based on the Power9 configuration, but the 9009-41G supports up to fourteen PCIe4 devices, eleven 6.4 TB Non-Volatile Memory express (NVMe) Solid State Drives for a total of 70.4 TB of usable NVMe SSD storage for an IBM i, AIX, Linux server or VIOS partition.     Performance gains of a IBM S914 9009-41G compared to a 9009-41A The 9009-41G performance gains to be had over its 9009-41A predecessor are in the backplane, storage and controller options selected. Compared to a SAS or SATA SSD, NVMe solid state drives provide significantly better read and write performance (latency), IOPS and bandwidth compared to SATA and traditional SAS SSDs. IBM NVMe SSDs (a.k.a. NVMe Flash Adapters) are directly connected to the Gen4 PCIe bus, and are assigned to a specific LPAR as a device. Whereas traditional SATA and SAS SSDs must rely on a controller and is shared with all the storage it manages.From a performance comparison perspective, NVMe SSDs can utilize most of the available bandwidth supported by the Power9 Gen4 PCIe slot which maxes out at 8 Gb per NVMe SSD, compared to only 6-12 Gb per storage controller (which must also be shared between all of the managed drives), and Gen3 PCIe has a 4 Gb/s maximum. Therefore, a Power9 SATA SSD could potentially achieve 200,000 IOPS on its best second, where as an NVMe SSD in an PCIe Gen4 slot can achieve over 1,000,000 IOPS. It is also important to note, the Power9 must also have the required V7R4 to use NVMe SSDs and other necessary PTFs and Firmware updates to achieve these performance gains.    Storage configuration options for the 9009-41G 41G Storage Options12 SAS HDD/SSD + RDX or 18 SAS HDD/SSD or 6 SAS HDD/SDD + 2 NVMe U.2 + RDX or 4 NVMe U.241A Storage Options12 or 18 SAS HDD/SSD or 4...
