The IO-PCE585-5I card is strictly an HBA (a Host Bus Adapter). This card provides JBOD access to the disks so that each can be independently accessed by the computer or servers operating system. Note that the cards will wiggle side to side and have play until screw is tightened. Do not over-tighten the screw! Some feature you may be giving up may actually help extend the life or endurance of your SSD such as compression and deduplication, as they reduce the number of writes performed on each of your vdevs (drives). So you want to add NVMe storage capability to your HPE Proliant DL360p Gen8 (or other Proliant Gen8 server) and don’t know where to start? Well, I was in the same situation until recently. However, after much research, a little bit of spending, I now have 8TB of NVMe storage in my HPE DL360p Gen8 Server thanks to the IOCREST IO-PEX40152. To disable them, I ran the following command in an SSH session (remember to “sudo su” from admin to root). synoservice --disable nmbd

As for the ML310e, it’s an entry level tower server. While it does support dual-height (dual slot) PCIe cards, it only has a single 350W power supply, misses some fancy server technologies (I’ve had issues with VT-d, etc), and only a single processor. I should be able to install the card, however I’m worried about powering it (it has no 6pin PCIe power connector), and having ESXi be able to use it. Using the dataset I created earlier, I configured a Windows Share, user accounts, and tested accessing it. Works perfect! Connecting the host Using RAIDz-1 or higher will allow for vdev (drive) failures, but with each level increase, performance will be lost due to parity calculations. It would not surprise me if, in all honesty, AM6 will only come populated with something like 8 m.2 slots and a single x16 PCIe slot on many models - at least in the consumer space. But this is all conjecture and rumors at this point.Mount the root partition of the SD Card Linux install to a directory. In my case I used directory called “old”. Shame I cannot share Crystal Disk screenshots here. If I could I think you would be impressed. How does Seq. 1 GB Reads at Q8T1 of 11,975.45 and Writes of 28,786.09 sound? I plan on running like this for a little while to continue to test the stability of the environment before making more changes and expanding the configuration and usage. Future Plans (and Configuration) I’ve been working on a few special top-secret projects for the blog and YouTube channel, and needed some cost-effective yet high performing NVMe storage.

Clearly iSCSI is the best performing method for ESXi host connectivity to a TrueNAS based NVMe Storage Server. This works perfect because we’ll get the VAAI features (like being able to reclaim space). iSCSI MPIO Speed Test Since option 1 is probably not going to happen, 2 or 3 remain. The only difference, really, between the two is how many m.2 slots you want to add to your mATX motherboard. I have heard rumors of up to 6 m.2 slots on the motherboard in the next generation high end boards, and even the low-end will have at least 3x m.2 slots. After resolving the issues mentioned below, I’ve been running for weeks with absolutely no problems, and I’m enjoying the increased speed to the NAS. Additional Important Information

NVMe Storage Server – Use Cases If I can populate the front drive bays, I can replicate the NVMe storage to the traditional HDD storage on a frequent basis to protect against failure to some level or degree. There are a number of considerations that must be factored in when virtualization FreeNAS and TrueNAS however those are beyond the scope of this blog post. I will be creating a separate post for this in the future. Use Case (Fast and Risky or Slow and Secure)

It’s now time to configure the sharing protocols that will be used. As mentioned before, I plan on deploying iSCSI, NFS, and Windows File Shares (SMB/Samba). iSCSI and NFS Configuration Nu I’m not really trying to completely swap to a different platform entirely, and finding a board with a bunch of M.2 slots natively would be fine - but then I’d still have that PCIe x16 slot that won’t be used at all. The current plan for the storage environment is for video editing, as well as VDI VM storage. This can and will change as the project progresses. The History Use the rsync command to transfer the SD card Linux install boot partition to the new boot SD card.If you’re worried about destroying your SD Cards, need some more space, or just want to learn something new, I’m going to show you how to use an NFS root for the Raspberry Pi 4.

Please note that consumer SSDs usually do not have PLP (Power Loss Prevention). This means that in the event of a power failure, any data sitting on the write cache on the SSD may be lost. This could put your data at risk. Using enterprise solid state drives remedies this issue as they often come with PLP. ConclusionWhen I insert the SD Card containing the Raspberry Pi Linux image, it appeared as /dev/sdb on my system. Please make sure you are using your proper device names to avoid using the wrong one to avoid writing or using the wrong disk. Virtualized – Once a month I had an ESXi PSOD. This was either due to overheating of the IO-PEX40152 card because of modifications I made, or bugs with the DL360p servers and PCIe passthrough.
