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.

Pros: Blazing speed, I have this hooked to a LSI 9211-8i HBA running under Solaris 11 Express with 6 of these Hitcchi 1.5TB's configured in raidz current getting 275MB/sec read and 225MB/sec write w/ dd tests. 400-550 Mbps on 1 GigE NFS/iSCSI served up through COMSTAR stack running 20+ vSphere VM's with very good performance. ZFS Open Storage Server saves the day!

Cons: None

Overall Review: This is a really great card in the respect that Solaris has great kernel/driver support for these controllers and they are natively JBOD HBA's and not full on RAID controllers which is what you want so the controller can step out of the way and let ZFS do it's magic. I have native dedup, compression, thin provisioning, snapshots, clones, and a rich Common MultiProtocol SCSI Target framework integration. Now lets see if Oracle can manage NOT to mess it all up and ruin it for all us geeks :-D

Cons: None, none DOA is always a good thing :-D
