Validate the OS is actually seeing the NIC with SRV-IO capabilities:
Get-NetAdapterSriov -Name "*"
If not, it's either a BIOS setting, specific PCI-E slot config, or not support at the motherboard level (unfortunately my case...)
Set-StoragePool -FriendlyName 'S2D on HVCLUSTER' -IsPowerProtected $true
"Indicates whether the physical disks that belong to the storage pool have backup power systems, such as battery backup. If you specify a value of $True for this parameter, the storage pool does not perform flush...
Hypothetical example of an organization with 3 departments, call them IT, Sales and Service.
Network Architecture Requirements:
Based on all hardware being Unifi series
Each dept is on its own floor, plus a data center on yet a separate floor (going for super simple mental representation...)...
Most importantly: Do you utilize a Unify Controller, either CloudKey, Pi or software?
If so:
Do you have a main switch the other switches wire back to, and your SG connects to?
For each network address range, did you setup a network in your controller? Are they "LAN/Corporate" networks or what...
Sounds interesting and FWIW - I have a complete homogeneous Unifi network with Pro4 SG, 4 switches (24pt POE, 3x 8pt POE) , 4x Pro HD APs and CloudKey controller configured with 3 wifi SSIDs (on different VLANs) and additional wired VLANs for lab stuff (some routed, some not) and 2 internet...
I've always been curious about the power draw of one of these systems. Have you ever plugged the unit in behind a Watt meter and measured the total power consumption?
I finally got around to updating the bios on my Supermicro X11SCH-LN4F motherboards today. And so far I'll say it's been a huge success. A couple things to note fixed in this release:
1. CPU consumption due to Interrupts: Before the update Core 0 on my E-2176G CPU would run at constant 80%...
Rack chassis cooling depends on many factors:
Qty/Form factor of drives: fully populated drive bays minimize total airflow through chassis unless it's 2.5" drives in a 3.5" bay. Higher RPM fans assist with this (hopefully more volume of air)
RPM of drives or SSD: How much heat are the drives...
Sounds very much like a setup I had once upon a time in Texas. 42u rack, 2x IBM BladeCenter chassis,2x 36drive bay storage servers, 2x 10Gb and 2x 1GB switches, a couple Juniper routers and F5 BigIPs. Also a 2 story house and fortunately the spare bedroom upstairs had a walk-in closet that...
Francis - you are correct, the thresholds are for the alarms themselves. Not nearly as elaborate as trying to build your own temp/rpm curve, but if you'd like to cap the maximum speed of a fan, the "Noctua NA-FC1 4-pin PWM Fan Controller" (Amazon) will do just that...
SM's current H11SSL-NC offers the LSI3008 RAID chip that supports up to 8 drives for your OS RAID. Their website only mentions "SAS" with the 3008 but I did inquire with SM's tech support with regards to SATA support and was informed it is supported and that 2 logical drives can be created (I...
I faced the same issue with Provantage and ordering a E-2176G CPU when it first released. I filled the delivery gap with a I3-8350K CPU that saw a month of usage and has been sitting in the desk drawer ever since. Also have a E-2174G that was utilized for the same purpose. They are available if...
PnoT - I think you're offering a pretty good deal. I've used the BladeNetworks/IBM/Lenovo switches for years and I've always appreciated their feature sets and free firmware availability. Plus I like the fact they can be managed via web or cli. I too have some of the G8000 / G8052 / G8124 /...
The Supermicro M2 PCI-E slots vary from board to board:
H11DSi: Qty 1 PCI-E 3.0 x2 lanes
H11SSL*: Qty 1 PCI-E 3.0 x4 lanes
H11SSW*: Qty 2 PCI-E 3.0 x2 lanes NOTE: 2 additional NVMe ports on H11SSL-NC model, plus a SAS RAID controller (and SATA as verified by SM)
New Server Specific Boards...
Once upon a time I use to do a lot of server hardware buy/sell on ebay, primarily to get stuff for my home lab. At that time vendors were charging corporate customers to pickup old server hardware in the DFW area, so I started doing it for free. I'd sell some stuff and then buy what I wanted. It...
A hard question I've yet to answer. I've primarily buy Supermicro, but I'm disappointed in their current lack of true Rome MBs. (vs complete systems) My focus is Hyper-V based HCI clusters so Memory, NVMe ports and PCIe slots are the priorities. And from a CPU point of view, it's not always Core...
Just a side note: The Microsoft Surface Dock is a Gen 1 device with 2 DisplayPorts. One port will support 4k @60Hz, but when utilizing the second port too, it will max out at 4k @30Hz. And everything is great as long as you stick with straight DisplayPort cables i.e., going through cable...
My current setup and power consumption. Being from the US, the CPUs were ordered from Provantage and I had to wait on them.
SuperMicro X11SCH-LN4F
Intel E-2176
4x 16GB
Chelsio T580 Dual Port 40GB via DAC cables
Adaptec 3154-24i
2x Intel Optane 480GB 905p (via M.2 cables)
2x Samsung 500GB...
For those interested: As an owner of several "SSDPE21D480GAM3" as posted in the picture, I can verify the kit DOES include the M.2 adapter/cable. This is a bonus for those wanting to utilize the drive with a regular motherboard with M.2 PCIe slot. Additionally, as per Intel
