How to Install HPE Smart Array P816i-a SR Gen10 Controller

Preparing for installation involves ensuring you have power disconnected and proper static grounding. The following steps outline a straightforward installation process designed to minimize downtime while maximizing card performance and reliability. Always refer to your server’s service manual for specific slot placement and cabling guidelines, and ensure compatible drive types and cabling are used to prevent performance bottlenecks.

  • Power down the server and remove the chassis cover. Ground yourself and any tools to prevent electrostatic discharge, then locate an available PCIe slot with enough clearance for the P816i-a Gen10 controller and its heat dissipation profile.
  • Insert the P816i-a Gen10 card firmly into the chosen PCIe slot, ensuring that the connectors are seated completely. Secure the card with the chassis screw or retention mechanism as required by your server model.
  • Attach SAS or SATA data cables to the controller’s ports and connect the other ends to your drive enclosures or backplane as dictated by your storage architecture. Use high-quality cables and avoid excessive bending to maintain signal integrity.
  • Power on the server and access the system firmware or management console. Install or update the HPE Smart Storage Administrator (SSA) or integrated management tools to recognize the new controller and to configure the FBWC and cache settings.
  • Initialize and configure your storage in SSA: define logical arrays (RAID groups), assign hot spares, and set up mixed-mode if you plan to use both RAID and pass-through. Validate that all connected drives are detected and that the cache policy aligns with your protection and performance goals.
  • Verify successful boot and run a basic storage test to confirm that the controller is functioning as expected. Monitor for any firmware or driver updates that may enhance compatibility and performance, and apply them according to HPE guidelines.
  • Document your configuration details, including RAID levels, cache settings, and drive mappings, to simplify future maintenance and upgrades. Regularly check for firmware updates and backup configurations to maintain data protection and system resilience.

It was worth every cent
Color: Cool Grey, Size: 24x24x12 inch
I have BPPV. It's a condition where tiny ear crystals come out of place and move within your ear canals - this fools your brain into thinking you're in motion, causing severe dizziness. The most common treatment is the Epley Maneuver, and that actually helps a lot. However, I was going through a period where every single day I'd wake up with severe dizziness. Even if I managed to do the Epley Maneuver and it worked, the entire rest of the day would be ruined because I'd still feel generally unwell and nauseous. I ended up getting a book about BPPV and the author strongly recommended sleeping at at least a 30 degree angle. So, that's why I ended up buying this wedge pillow... I started using it April 26 and today is May 17. Since I began using it as a pillow, I have not woke up dizzy again. That is so huge! It may be that sleeping at a 30 degree angle deserves 5 Stars but thought I'd give this pillow 5 Stars too, as it's been a great experience. If you suffer from this, here's how the angle should be...If you lay your head on a pillow and open your eyes, you should not be looking at the ceiling. With the right angle, you should be looking at where the wall meets the ceiling. If so, you know you're at the right angle. As far as pillow itself, I'd say the pillow case fabric is of average quality. Not really remarkable in any way. It seems decent. Good value for the price. The inside is firm (which is just what I needed) but comfortable, and I tend to not move around much the entire night. I like this very much and if it does start wearing out, I'll definitely come back here and buy another. Would recommend.

A bit too firm but great otherwise
Color: Cool Grey, Size: 24x24x12 inch
I got this wedge pillow primarily to have something to lean my head against (I like to lay on my side when reading or looking at my phone at night sometimes), or to sit upright when reading in bed. It's very comfortable doing both now. It does a really good job at being a nice support for the back of my bed. Only negative is I feel it's too firm. I wouldn't use it as a primary pillow, but it's definitely good for back support at least. While I won't mark it down for this, I do find it very large. If you have anything smaller then a queen it may take up more of your bed then you'd like. Definitely recommend. Hopefully will last quite a long while as well.

So helpful after surgery.
Color: Solid Warm Gray, Size: 24x24x12 inch
Perfect support while recording from abdominal surgery. This pillow maintains its shape and is not overly soft. I used it vertically as a prop for watching television and then used it horizontally to prop myself up to sleep, once I returned to sleeping in bed. I used this daily for 6 weeks or so following surgery. The cover can be removed and machine washed. The non-slip nubbies are helpful. This pilllow is high quality and really helped to minimize pain and improve my sleep after surgery.

Nice wedge pillow but not enough...
Color: Cool Grey, Size: 24x24x12 inch
It came compacted and when I opened it expanded almost immediately, maybe took like 20 minutes to fully decompress. Its soft and comfortable and the cover is really nice. But it does have a strong chemical smell, which is normal for this kind of brand new memory foam, I just put it on a table with a window open near it and after maybe 24 hours the smell was almost completely gone. The problem is that I bought this to have a elevated position when sleeping but the 30° are just not enough for me. I wish it was at least 45° but I could not find any pillow with that amount of degree... it's either 30° or like 75° in the other position. At the base of the pillow there is a little ridge that is comfortable for the lower back but makes me slide down in the middle of the night so I end up almost laying flat with my neck on the base ridge. With my slim build my lumbar area gets some nice support but makes my head almost have a "fall backwards" sensation, I like having my neck have a "push-forward" position with my pillow, but when adding another pillow to try and get to a comfortable position it only makes me slide down even more... :/

Very firm and durable
Color: Cool Grey, Size: 24x24x12 inch
worked great for husbands surgery recovery. Very affordable, firmness was great, looked nice on the bed and also used it for the grandkids when they were watching a movie. Moved around with ease. Didn't use it to sleep with all night though. He could only make it half the night but that wasn't the pillows fault. It was the cast on his arm. Definitely did its purpose after surgery and the need to sit up in bed more. highly recommend
