Mount the boot partition of the SD Card Linux install to a directory. In my case I used directory called “old”. I needed to create a Windows File Share for file based storage from Windows computers. I plan on using the Windows File Share for high-speed storage of files for video editing.

What’s interesting is that I was able to achieve much higher speeds using this card in an older system, than directly installing one of the SSDs in a new HP Z240 workstation. However, unfortunately due to CPU limitations (maxing the CPU out) of this server used above, I could not fully test, max out, or benchmark the IOPS on an individual SSD. Additional Notes on the IO-PEX40152 This is a fantastic card that you can use reliably if you have a system with a free x16 slot. Because of the fact it has a built in PCIe switch and doesn’t require PCIe bifurcation, you can confidently use it knowing it will work. The risk can be lowered by replicating the pool or dataset to slower storage on a frequent or regular basis. Slow and Secure 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. This also protects your SD card, as the majority of the reading and writing is performed on the physical storage of the NFS export, instead of the SD card in the Pi which has limited reads and writes. What you’ll needNFS provides a cleaner mechanism, as the FreeNAS handles the unmount of the base filesystem cleanly on shutdown and to the ESXi hosts it appears as an NFS disconnect. If VMs are not running (and no I/O is occuring) when the FreeNAS instance is shut down, data loss is not a concern. iSCSI MPIO (Multipath I/O) If you’re running Ubuntu, your existing nobtcmd.txt should look like this: dwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

Take note of the mount point and/or NFS export path, as this is the directory your Raspberry Pi will need to mount to access it’s NFS root. This is also the directory you will be copying your SD Card Linux install root FS to. Copy the Linux install to the NFS Export When you use an NFS Root with your Raspberry Pi, it stores the entire root filesystem on a remote NFS export (think of it as a network filesystem share). This means you’ll have as much space as the NFS export, and you’ll probably see way faster performance since it’ll be running at 1Gb/sec instead of the speed of the SD Card.

Disabling sync will allow writes to be marked as completed before they actually are, essentially “caching” writes in a buffer in memory. See below for “Ram Caching and Sync Writes”. Setting this to “standard” will perform the type of write requested by the client, and setting to “always” will result in all writes being synchronous. Boot Support– Installing this card in different systems, I noticed that all of them allowed me to boot from the disks connected to the IO-PCE585-5I. In addition to the above, the IO-PCE585-5I provides 5 SATA 6Gb/s ports and uses PCIe 3 with 2 PCIe lanes, to provide a theoretical maximum throughput close to 2GB/s, making this card perfect for SSD use as well! We all love the word multipathing, don’t we? As most of you iSCSI and virtualization people know, we want multipathing on everything. It provides redundancy as well as increased throughput. How do we turn on NFS Multipathing? I’ve had this configuration running for around a week now with absolutely no issues, no crashes, and it’s been very stable.

Now press escape, then type “:wq” and hit enter to save and close the vi text editor. Run the following command to make the script executable. chmod 755 speedup.sh 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. In this post I’ll be reviewing the IOCREST IO-PEX40152, providing information on how to buy, benchmarks, installation, configuration and more! I’ve also posted tons of pics for your viewing pleasure. I installed this card in an HPE DL360p Gen8 server to add NVME capabilities to create an NVMe based Storage Server. I logged in to iLo on the server, and watched the server perform a BIOS POST, and start it’s boot to ESXi. Everything was looking well and normal. They also note that contents may vary depending on country and market. Unboxing, Installation, and ConfigurationMount the new boot partition of the boot SD card to a new directory. In my case I used the directory called “new”.

For some time I’ve been trying to source either an Nvidia GRID K1/K2 or an AMD FirePro S7150 to get started with a simple homelab/demo environment. One of the reasons for the time it took was I didn’t want to spend too much on it, especially with the chances it may not even work. After enabling this, I noticed that RAM and Memory usage had drastically increased on the Synology NAS. This would peak when my ESXi hosts would restart. This issue escalated to the NAS running out of memory (both physical and swap) and ultimately crashing.

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 After you do this, the Linux SD image may not boot again if directly installed in the Raspberry Pi, so make sure you’ve made the proper modifications before powering it down. Create the NFS Export NFS VM datastore is used for testing as the host running the FreeNAS VM has the NFS datastore store mounted on itself. To disable them, I ran the following command in an SSH session (remember to “sudo su” from admin to root). synoservice --disable nmbd If using a SLOG for ZIL, it is highly recommend to use an SSD that has PLP (power loss protection) as well as a mirrored set to avoid data loss and/or corruption in the event of a power loss, crash, or freeze.
