Anyone had personal experience comparing Ruckus 802.11ac/ax APs versus Cisco Aironet highend 802.11ac (like 3802/4800) or C91xx 802.11ax APs? Fun thing is Cisco C9117 are basically Ruckus R730 in disguise, and C9130 = R850, although Cisco added their additional RF chip magic.

Depends on your goals I think. W-2400 series is for people who need a lot of Pci-Ex lanes and RAS features of RDIMMs

It's sad that only W790E-SAGE and X13SWA-TF has 8 memory channels. And X13SWA-TF has very weak VRM and still zero overclocking features in BIOS, so basically there is only one (SAGE) usable motherboard for that platform.

Sad thing - how ugly x3950 x6 looks with a full size PCI-EX book with GPU inside :)

Those platforms retrain memory on each cold start, no wonders its 10+ minutes each time

I would recommend you reading "White Paper FUJITSU Server PRIMERGY & PRIMEQUEST Memory performance of Xeon E7-8800 / 4800 v2 (Ivy Bridge-EX) based systems".

If your proliant is DL560Gen8 - upgrading to E5-4657Lv2 is a great idea, v2 cpus are WAY better. From my experience, DL560Gen8 has such a poorly designed cooling system, it would overheat if you install four E5-4650 in it, it's actually one of the worst platforms for a quadsocket E5 enthusiasts...

Check FRU numbers of the books you're using, I had exactly same issue with different part numbers of books in one server.

No, E7 wont work in E5 platform. E5 has internal memory controllers, while E7 has Scalable Memory Buffers instead of "raw" Memory Controllers.

I think test was at ~3.2Ghz

If you look at seller photo, you will see " Exact part no. 662525-001 " on it ;)

IBM - Price, amount of bugs, performance, support. The only cool thing about X6 were their DDR SSD sticks IMHO. Cisco and Huawei is probably most flexible ones from this generation. Oracle is best considering HW and FW engineering and the only one where you can get E7-8895v2 CPUs officially with...

Funny enough, if we talk about E7 v3 + DDR3 - almost every vendor except HP and Dell supported those configuration. Cisco UCS series support v3 with DDR3 ram, Oracle (which in my opinion almost always best engineered servers), even Huawei supported DDR3 with v3 Xeons. I had some experience with...
