    EMC KTN-STL3 15 bay chassis

    WARNING! Hmm. So I got a deal on SAS3 12GBPS Controllers for my KTN-STL3 for $50 each. Part Number is 303-300-000C-02 My existing controllers are part number 303-108-000E The problem is that the alignment pins prevent the new controllers from being installed, so they are apparently NOT...

    Finally: Overclocking EPYC Rome ES

    Hi all, I started using EPYC for my workstation. I saw this thread and was wondering what some of my options may be. I have an H11SSL-I and a 7302p. Are there any 16 core QS part numbers I can purchase? Basically looking for an alternate (cheaper) upgrade path vs buying a 7F52. My 7302p stays...

    TrueNAS Scale NVME Performance Testing

    Over the past year or so I have been obsessively exploring various aspects of ZFS performance, from large SATA arrays with multiple HBA cards, to testing NVME performance. In my previous testing I was leveraging castoff enterprise servers that were Westmere, Sandy Bridge and Ivy Bridge based...

    Lowest Power Consumption NIC

    Hi All, Not sure if this is documented somewhere, and I am sorry if I missed the topic. Looking for the most efficient dual-port 10 gig NIC for a homelab server. SFP+ cage is probably obviously lower power than copper. Intel X710? Connect-X 4? Chelsio?

    NVME U.2 Disk Enclusers

    Hi All, Just wondering, I have bought a variety of disk shelfs over the years from a bunch of vendors. Perhaps I just don't know where to look or they are just too new to be showing up in places like eBay. I know there are some Tri-Mode external HBA cards from Broadcom like the 9500-8e: HBA...

    Hey man, any idea what the part numbers for IOMs and PSUs are for the 2U 25 bay 2.5" DAE? The PSU I have is 071-000-541 and is rather loud.

    NetApp Flash Cache

    Not sure if these will even work in a standard server, if there are drivers required or anything else.... But 2TB of PCIE storage for less than $90 is interesting. NetApp Flash Cache II 2TB PCI-E Module 110-00202 111-00904 | eBay

    Router hardware recommendation - > 1 Gbps WAN

    I just went through a similar exercise. A new ISP on my area started offering 2Gb Fiber to the Home. Hand off is RJ45 10 gig from an XGS PON ONT. I picked up this bundle Supermicro X11SSQ-L-DE05B Embedded Intel G4600 Chip plus 8GB RAM 974575260957 | eBay And an Intel x710-da4 (a Cisco ucs...

    A funny story about pfSense

    I posted this on reddit and figured I would share here too because I think it's hilarious. So for my day job I am in charge if a relatively large enterprise with about 30,000 total users. For Firewall on the edge we have had both Fortigate and now Palo Alto. For everything else, we have been...

    pfsense Multigigabit

    pfsense Multigigabit

    Hi All, Posting to see if others have any experience to speak of when it comes to pfsense with multigigabit WAN connections. Recently an ISP in my area began offering FTTH with 3 offerings, 500/500 1000/1000 and 2000/2000. I just booked installation for next weekend for the gigabit tier for...

    ZFS without a Server Using the NVIDIA BlueField-2 DPU

    So let me try and unpack this. Much like in your demo, Intel is literally making the network cards into a SAN at the same time as they are shipping iSCSI LUNs to your compute? How do the cards talk to the NVME devices, are the cards themselves the PCI-E root? Is the DPU/IPU literally taking over...

    ZFS without a Server Using the NVIDIA BlueField-2 DPU

    Sure, but without the specific data comparisons, it's difficult to compare to native PCI-E fabrics with HBA cards (which have PLX switch chips that I'm sure also introduce latency?) to RDMA. Perhaps that's an opportunity for you to explore some day for us dear readers :) Still, native PCI-E is...

    ZFS without a Server Using the NVIDIA BlueField-2 DPU

    @Patrick I am trying to understand what this would look like from a reference architecture or best practices deployment guide for a datacenter. A "traditional datacenter" would look something like this: Or something like this: I guess what I am having trouble grasping is how you would...
