Boot off PCIe SSD?

Recommended Posts

Well, I bought this card and this SSD

I install this combo into my ML310e Gen 8 v2 server. I would like to install my Fedora 21 Server OS onto this PCIe SSD M.2 card and boot from it keeping the HDDs in the bays for data.

So far, I have set the SATA Controller to AHCI mode and tried to run the install, but the Fedora installation only give me the choice of the HDDs in the bays. :(

 

How can I test that the server is recognizing the PCIe SSD drive and how can I set it to be the bootable controller?

 

Thank you.

Your SSD isn't PCIe. The M.2 standard has PCIe + SATA + USB together on the same connector.

 

You have to plug it into the top slot on your card and connect the SATA socket to something. When the Gen8 Microserver SATA controller is in AHCI mode, you can't boot from the SATA ODD port on the motherboard.

My apologies, I linked the wrong card.

This is the one I have: Addonics ADM2PX4 M2 Pcie Ssd Pcie 3.0 4-lane Adapter.

How can I make it bootable and install an OS on it?

That is the wrong card for your SSD as it is only for PCIe SSDs. Your SSD is a SATA based one and needs a connection to a SATA port. Putting it into an adapter for M.2 PCIe cards won't work. The original adapter you linked has a slot for M.2 SATA and M.2 PCIe. Edited by GotNoTime

Ah, now I see my mistake.

PCIe SSDs are expensive. The best price for a 128GB I can find is approx CAD$200. That's much more then what I was hoping to spend on this solution. Even then, I'm not guaranteed this server can boot off the PCIe, correct?

 

What would be my best cheapest option at this point?

 

I'm pretty much ready to throw in the towel and stick a small HDD into the first bay for the OS and be done.

I really wanted to keep the bays for data only as I'm starting with 2x2TB WD Red HDDs and I was going to put a 1TB HDD into a 3rd bay for home NVR purposes leaving me one bay for expansion. Now, I will have no room to expand without replacing drives. :(

Would SSHD drive work well in the ML310e? If I could find one with 32GB nand and 2TB platter that would work for me with OS on the SSD portion and I would not lose the bay completely to OS drive.

If it is a NVMe SSD then no. It won't boot as the BIOS doesn't support NVMe. If it appears as a SATA controller or has a boot ROM then it should boot but still no 100% guarantee of this.

Hybrid drives don't work like that. The flash portion is used to cache frequently accessed data on the HD part. You don't separately address it as it is all handled by the drive electronics.

 

What OS are you intending to use? If it is Linux or ESXi then you can install to a SD card.

Ah OK. Yes, I read more on the hybrid drives, now I understand how they work. Thank you.

 

I think I will just take the (hopefully) easy route and get a normal 2.5in SSD, stick it into a 3.5in adapter and put it into the first bay. When the time comes and I really need the bay I'll get one of those StarTech PCIe SATA controllers and connect this OS drive to that.

 

I will be installing Amahi OS - it's based on Fedora 21.

      Good afternoon folks!
       
      I have a question I was wondering if someone would know about. I have a Microserver Gen 8 with Vmware ESXI 7 currently installed on the MicroSD with AHCI enabled instead of RAID mode (dont find anything usefull in raid mode in my current setup other than booting from ODD, which I can just use as another Datastore instead).
       
      With that context being said, Im trying to enable the Agentless Management Service from the ILO with the drivers on the Vmware ESXI 7, but unfortunetly after installing and trying to start the service with:

       
      /etc/init.d/hp-ams.sh start  
       
      I get the following error:
       
      /opt/hpe/ams/amshelper: error while loading shared libraries: libnicmgmt.so.0: cannot open shared object file: No such file or directory  
       
      Makes sense following the Vmware ESXI HPE support matrix, since its only supported until Vmware ESXI 6.5U2 Pre-gen. But I´ve been reading lots of people having working setups doing the following:
       
      Install Vmware ESXI HP Custom Image 6.5U2 -> Offline Update to Vmware ESXI 6.7.
       
      I was wondering if installing HP Custom Image 6.5U2 with the drivers Agentless Management Service working and doing a full upgrade to ESXI 7.0 would do the trick, since its an upgrade not a clean install...so libraries should stay supporting older drivers installed.
       
      Does this make any sense?? Has anyone gone trough this alredy?
       
      Thanks!

      All credit to schoondoggy for his original idea. A shame I am on the wrong side of the Atlantic to order an SDM kit as the import duties make it an expensive option, or would have if they were still available. I had to look around to see what alternatives I could find... and managed to find the bits needed on Amazon!
       
      I must admit I am rather pleased with the end result of this project and may repeat it on the other Gen8 MicroServer. The outcome is a server with a mirrored system drive on the internal B120i, and the main drive bays connected to an HP P222 card providing a RAID-10 data volume. This is pretty much my ideal setup for a stable resilient but small server.
       
      Sabrent 3.5" to x2 SSD Internal Mounting Kit (BK-HDCC)
      Amazon UK - https://amzn.to/32qEVou
      Amazon US - https://amzn.to/3h8Blom
      The kit comes with all the cabling you need and all the required screws to mount the drives and bracket.
      Two types of power splitter cables are included along with two SATA cables. The bracket holds two SSDs and provides a small gap between them.
       
      I mounted the bracket next to the PSU but leaving a 2-3mm gap to allow for some airflow past the SSDs in case they get warmed by the P222.
       
      Tips:
      Put some insulating tape along the underneath of the upper chassis rail next to the PSU and drilled three small holes.
      I used two strips on to stop the drill bit from walking across the metal. Drill with a 2mm first then a 2.5mm bit. This leaves enough metal for screws to thread in.
      Check and measure each hole against the bracket as you go so that they line up. Bracket is then fixed in place using the provided screws (see photo).
       
       
      The final part of the puzzle is another Mini-SAS to SATA cable the same as the one connected to the internal drive bays.
      This is an SFF-8087 Mini-SAS [male] connector to 4 SATA [female] header cables. The 50cm cable from Jyopto works great and not too much spare to lose within the system.
      Amazon UK - https://amzn.to/2CXAzgb
      I could not find it on Amazon US site but there was one from CableCreations that same length.
       
      Just need to add your choice of SSDs and cable up to B120i port.  I went with Samsung 860 Pro SSDs for the longer rated lifespan of write cycles.
       
       
      I decided to forget about an internal DVD/RW drive and opted for an external HP F2B56AA slimline drive that can be plugged into the USB of either system.

      Sabrent also make a really good quality 2.5" to 3.5" bay converter adapter (BK-PCBS) that I have used in the EX490/X510 to convert from HDD to SSD system drives.

      Hopefully this information will prove useful to some looking to update their MicroServer.

      Hi! I am planning to buy a Microserver Gen10 Plus E-2224 for a small business, and want to add as much disk space as possible. I already have the older Gen10 with 4x4TB HDDs in RAID10 (effective capacity 8TB) and a 2TB SSD in the 5th slot (which is missing on the new G10 plus). The max stated capacity on the HPE site seems to be limited with their own enterprise HDDs, so I'd like to see if I can go for bigger disks. The server would be running a sort of an application which collects lots of data from devices, and the data tends to grow over time (1-2TB per year), and I'd prefer not to worry about the capacity for the next several years.
       
      My primary concern is the max capacity (max single drive capacity + max total RAID capacity with the Smart Array S100i) I can reliably install. If possible, some actual setup which has been shown to work with 32GB RAM and its limited 180W power supply? I was also planning on upgrading it to 32GB. If I am buying a 16GB RAM server, does this means it has both slots occupied with 8GB modules and I need a 2x32GB kit? For the os SSD, I won't have the PCIe slot available because we need to insert a certain GPS PCIe card that the server uses for time synchronization. So, if I want an SSD, this means I should use something like 1xSSD + 3xHDD in RAID5, instead of RAID10?  
      I've been planning to install 16TB Seagate Exos X16 drives, with rated max operating power at 10W (6.3W for random reads/writes). Does this seam feasible?
       
      Thanks a lot for your tips!

      Does anyone know if it is possible to get Agentless Management Service (AMS) running on Debian/Ubuntu Linux? It is always showing as Not Available in the iLO page and I have only ever seen this active in Windows.
