5 out of 5 eggsSmokin fast 10Gbps SFP+ dual port adapter

Pros: Working like a champ in my vSphere 5.5 home lab. Pushing max theoretical 10G throughput (roughly 9.7Gbps) using iperf VM to VM on different hypervisor hosts hooked to a HP procurve 2910al w/ 2 J9008 dual port 10G SFP+ modules. I used a direct attached copper (DAC)/twinax cables I got off the infamous bidding site we all know and love for about 1/3 of the price of typical 3m twinax cables and they were HP branded/part numbered as well.

Cons: None that I know of thus far other than reputable 10G switches are pricey still, at roughly $200 per 10G port you really can't gripe too much for the adapter though if you plan to use twinax and for-go the cost of optics which is great for short-haul.

3 out of 5 eggsFirmware locked optics

Pros: These cards work well. Very well supported open source drivers, and well maintained by Intel. They generally Just Work.

Cons: Artificially firmware locked to Intel optics. Absolutely unforgivable in a datacenter environment. Want to migrate that Twinax connected server across the room and need to swap to LR optics? You're out of luck and you better hope the entire ops team realizes this before scheduling anything. Lord help you if you find you're out of the right length twinax and need to get a server up quickly during an emergency!

Latest Linux drivers have a module load parameter you can use to disable this ridiculous firmware check. However, if you run these cards w/ a statically compiled kernel you must modify the driver source to get around the vendor lock.

Other Thoughts: Great performance, well supported, but absolutely inexcusable artificial vendor-lock for optics. Look at picking up the Supermicro branded versions of these cards (no firmware lock), or looking elsewhere at Myrinet for a company that makes extremely well performing cards that don't play games that make operations hell.

If you run Linux and can live with using loadable modules, you can also disable this check.

No Intel, I am not going to stock a bin of optics just for you in every location.

5 out of 5 eggsWorks

Pros: Generally available to consumers. Working fine with GBIC transceiver by Axiom, model E10GSFPSR-AX and multi mode fiber cable in Windows 2008 R2 with Intel driver version 17.0.200.2 on Supermicro X8DTU-F linked to HP switch.

Cons: 10G still too expensive.

5 out of 5 eggsFaster than quad gigabit

Pros: When feeding 3Gbaud traffic with standard 1500byte frames thru this NIC, performance is better due to interrupt offloading capabilities, compared to Intel Quad-port gigabit NICs.

Cons: None to mention.

5 out of 5 eggsExcellent for Nexenta + ESXi

Pros: Extremely pleased with these, but I did my homework before purchasing. They compose a VMware vSphere 5 storage network.

2x Dell 8024F switches
5x Dell R710s with one of these cards in each server (ESXi 5 hosts)
1x Dell c2100 Server running NFS off of Nexenta CE 3.1.3 with 2 of these cards in it (one PCI based as sold here and another that is a mezzanine card) for an aggregate 40Gbps throughput to/from the SAN.
tons of Cisco SFP-H10GB-CU3M/SFP-H10GB-CU1M cables used for connectivity.

These were chosen for compatibility/reliability as we planned to build our own SAN solution after pricing every storage vendor we could fathom. We ended up spending a fraction of the quotes we were offered and got more for our $.

Shipping as always was remarkably fast w/ NewEgg.

Cons: Cost? They can be had elsewhere for substantially less.

Other Thoughts: Do your homework and buy the right cables, etc for these and you won't regret it.

5 out of 5 eggsEXTREMELY fast.

Pros: Installed several of these in different platforms. No compatibility problems with Windows server, VMware ESX 5 or QNAP SAN.

Cons: The are pricey, 10x fast as gigabit, but more than 10x the cost of gigabit.

Other Thoughts: If you are going to use these with SFP+ direct connect cables DO NOT BUY AN OFF BRAND CABLE! These cables have firmware chips in them that negotiate the connection. Get either the Cisco or Netgear cables they have here at Newegg.

5 out of 5 eggsIn Contrast

Pros: In contrast to other reviews I figured I had to add that this adapter does work well with Copper Twinaxial cables, Cisco included. I have one of these adapters in a storage server I built using iSCSI as the protocol. This adapter hooked up seamlessly with a Cisco Twinaxial cable to a Cisco 2960-S (certain models of the 2960-S have 2x 10-Gigabit SFP+ modules.) that particular server now acts as a SAN in my network, jumbo frames fully supported and doesn't show the slightest sign of slowing. The Cisco Twinaxial cable combined with this adapter gives the benefit of significantly lower latency than its Cat-6 ethernet relative and provides outstanding results in my setup.

Cons: As the other reviewer stated, it seems it is not compatible with certain transceivers, you may want to check compatibility if you are planning to use this in a fiber network. Again if you are sticking with copper, the Cisco Twinaxial cables work just fine.

3 out of 5 eggs

Pros: Well packaged.

Cons: Only compatible with two Intel SFP+ transceivers, the E10GSFPSR or the E10GSFPLR. Specifically didn't work with my Cisco SFP-10G-SR modules.

Other Thoughts: Won't work with non-intel SFP+ transceivers.

The marketing materials say:
"Intel’s family of Intel® Ethernet X520 Server Adapters with SFP+ connectivity are the most flexible and scalable Ethernet adapters for today’s demanding data center environments."

Not flexible enough, in my opinion.
