My clients don't care about the minimal loss in power savings. Instructions: This has to be a bug in the bios or the microcode of the CPU. Resolution: In the PowerEdge Bios, change the System Profile to Performance Optimized. If your CPU has been tested and is not overheating, this is the workaround: Multiplier would not increase from 12 and the server was running at ~1.2ghz. This also happened to another client T320 Server with Server 2008 R2 with an Intel Xeon E5-1410. The CPU would go down to below 0.20 Ghz and the 2012 server would crawl and service availability was seriously degraded. On the Server 2008 R2 server it only happened a couple of times at random. On the Server 2012 R2 server, it was happening randomly only once or twice a month. This is a known bug with Dell PowerEdge T320 Servers with a Intel Xeon E5-1410 v2. I stress tested the cpu on both and observed no overheating. One had the latest bios (Server 2012 R2) and the other had an older bios (Server 2008 R2).
The other, Windows controlled (yes Windows power settings were set to Performance). T320 with Xeon E5-1410 will throttle and get stuck at low speed. I've seen here that someone got the same problem on the same switch and it could be related to a memory problem, I upgraded the firmware from 6.1.0.6 to 6.2.0.5 but no luck, I decided to try another switch but I got the same problem (i copied the configuration), so it seems that the problem is not really related to the switch.īefore the N2048P we were using a small Netgear Prosafe FS116P without any apparent problem (it is unmanaged tho), any though on what it could be or on how can it debug the problem? Note that the device attached to the port 22 is NOT one that gave us warnings about pings

Our network monitor says that some of the devices attached are losing pings every now and then (even if we can't see any packet loss with a manual ping) and it gets this error from the switch via SNMP:ĬRIT - (up) MAC: f8:b1:56:62:b2:fa, 10MBit/s, in: 57.19B/s, in-errors: 2.78%(!!) = 0.1, out: 4.68kB/s We just got 10 N2048P and we were going to try one of them in the current enviroment before deploying all of them, unfortuntaly we got those errors in the log:Īpr 28 09:58:08 SW-SPES-06-1 DRIVER: broad_hpc_drv.c(4428) 366 %% Unit: 0 #012 CDC RX FIFO entry 44 double-bit ECC errorĪpr 28 09:58:08 SW-SPES-06-1 DRIVER: broad_hpc_drv.c(4428) 367 %% Unit: 0 #012 CDC RX FIFO table 0 entry 44 ECC errorĪpr 28 09:59:50 SW-SPES-06-1 DRIVER: broad_hpc_drv.c(4428) 369 %% Unit: 0 #012 CDC RX FIFO entry 28 double-bit ECC error
