    Aruba 2920 / Intel X540 NICs not working at 10GB speed?

    I have an Aruba 2920 with the J9732A 10Gb expansion modules, and 3 PCs with the Intel x540 t1 10gb cards. For some reason I simply cannot get this setup to actually work at 10Gb speed. The connections all indicate they are negotiating at 10Gb, but iPerf caps out at 2.5Gb. Initially I used a...

    80m 10base-t copper transceivers

    I’ve been following STH reviews of 10base-t sfp+ transceivers for a while. Most appear to be based on a Marvell chipset with a 30m rating and 2-3W power draw. This means they get very hot. Recently, I’ve noticed some manufacturers like FS and 10gtek offering 80m models based on what appears...

    WTB ICX7250-24 + 4 x 10GBase-T SFP+ Transceivers

    WTB - figured it was worth a shot ... Brocade ICX7250-24 w/ears or 24P [1] 4 x 10GBase-T SFP+ Transceivers or maybe 6x [1] Don't need PoE, so don't care to pay a premium for it. Obv I understand the -p version is "worth" more. Thx

    Need reasonably priced (Under $2K) 8 to 24 port 10GBASE-T switch with 40Gbs QSFP+ uplink

    We have two separate dual-controller 10GbE iSCSI SAN's (VESS R2600tiD) on the network and have found that when more than one user is writing 8K uncompressed (4:4:4) 12-bit video data out (approx. 9Gb/s) to their LUN (virtual iSCSI drive) it overloads the Network Bandwidth quickly. Since there...

    Hoping for a low cost switch with strong backplane, 4x1Gb, 4x10Gb and decent LACP handling

    New member. Love the YouTube videos. Hoping this is a good place for me to ask this question: I'm really in need of a lower cost 4x 1000BASE-T + 4x 10Gb (at least two SPF+) switch with decent backplane and good LACP handling. I'm having trouble searching the web for a a lower cost switch, so...

    NAS with 10gb/s internal and external speed.

    I want to buy a NAS (Synology, QNAP, Buffalo, etc.,) that allows me to get 10gbit/s speed. My preference is to use my 4 WD Red NAS HDDs. I assume that to get 10gb speed, I will have to have some sort of read/write caching capability. So I assume that it will need to have capacity for a couple...

    Hey folks, Building a new firewall with the Chelsio T520-CR card and need to validate a few points before I pull the trigger: Will the Chelsio T520 negotiate lower than 10GBASE? My homelab is 1000BASE-T and I'm slowly upgrading Edit: Looks like the card supports 802.3z which would mean it...

    Switchless 10GbE Point-to-Point Connection between ESXi Servers [how?]

    I bought 2 servers with X9DRH-7TF motherboards and each server has 2 x 10GbE RJ45 NICs. Currently those servers and all other clients are connected to a 1 Gbps switch (Cisco SG-300). I'm not sure what the term is for a point-to-point, switchless connection between the two servers using 10GbE...

    Used Genuine 10G Base T Intel NICS

    Apparently the x540-T2 I picked up from eBay last year is a counterfeit. I didn't realize it until I started looking around and came across this thread linking directly to the card I purchased. Chinese X540-T2 on ebay is a counterfeit? In the interest of picking up genuine replacements, can...
