Thank you for contacting Intel® Rapid Storage Technology enterprise (Intel® RSTe) support and in regards to your situation we'll be more than glad to help you; in order to determine which way will be the most appropriate to assist you we'll need that you send us the Technical Specifications of your machine such as:
Motherboard Model and Manufacturer:
Amount of RAM that you have installed:
Number of Storage devices and their capacity (SSDs and HDDs) on your machine:
The Drives are used in a RAID (0, 1, 5, 10) configuration?:
Exact version of Intel® RSTe (Enterprise):
If possible please attach us the LOG Files generated by RSTe, depending on your Windows Version they could be found in the C:\Users\[username]\Intel folder or also you can use the Email option on the RSTe GUI to generate a report for your equipment.
Once you've sent us that information we'll proceed with the necessary assistance and if you have additional details to add your situation or want to ask additional questions please don't hesitate to contact us, we'll be glad to assist you.
Intel NVMe x4 P4600 2.0TB
The drives appear as available drives in RSTe GUI (have not configured them yet as a RAID5 array)
SuperMicro SSG-6049P-E1CR24L (Motherboard X11DPH-T)
Processors(2): Intel Xeon Gold 6154 CPU @ 3.0 GHz
64 GB DDR4@2666Mhz
OS: Win2016 Datacenter
Drives Connect to Server via PCIe Gen3 PLX based Host Card
I have attached the System Report from RSTe to this reply.
Thanks for the information that you've provided, in regards to your situation that you're experiencing the Intel® Rapid Storage Technology enterprise (Intel® RSTe) package already contains and installs the required NVMe Drivers for your drives to be able to create a RAID without any issues.
Based on the RSTe Report that you've shared with us, it shows up the Drives as Available to be part of a RAID set, so the correct drivers are installed for your drives and you'll be able to create a RAID5 Array.
Additionally, please remember that if you require more assistance or want to add additional details, we'll be glad to assist you
I noticed that command queueing is not enabled for the NVMe drives.
You can see evidence of this by looking at the information in the attachment I uploaded in my previous reply.
For example, this is the information for one of the 4 NVMe drives:
Disk on Controller 2, Port 1
Type: NVMe SSD
Location type: Internal
Size: 1,863 GB
System disk: No
Disk data cache: Enabled
Command queuing: None
Model: INTEL SSDPE2KE020T7
Serial number: BTLE736000SE2P0DGN
SCSI device ID: 0
Physical sector size: 512 Bytes
Logical sector size: 512 Bytes
Why is command queueing not being used?
In addition to the Intel P4600 drives that I used in previous reply, I also tried the following types of Intel NVMe drives:
- Optane 900P
In all cases, the Disk Properties shows
Command queuing: None
Is this indicating that RSTe and/or the NVMe drives are not properly configured for optimal performance?
Thank you for your patience.
Please find the answer to your questions below:
- Why is command queueing not being used?
- Is this indicating that RSTe and/or the NVMe drives are not properly configured for optimal performance?
Command queuing is a remnant of the HDD SATA days where native command queuing (NCQ) was used to optimize the number of revolutions on the disk when acquiring data.
In the RSTe report where it shows a SATA and an NVMe drive, the value shown for ‘Command Queuing’ is only relevant to SATA space and ‘None’ is only put in the field as a courtesy for NVMe since it is not defined in NVMe space.
We hope you find this information useful.
