What is Gen5 Fibre Channel?
Speed-based naming changed to generational-based naming
New advanced protocol services and features running multiple
speeds
– Not just bandwidth improvement
– 16GFC, 8GFC, 4GFC speeds
– Maintains backward compatibility to previous FC generations

Emulex ExpressLane™
SSD Latency Challenge
•
Flash storage shares the SAN
with traditional rotating media
•
•
4
QoS Solution
•
ExpressLane creates separate
queues for low latency storageIdentified by LUN
Mission-critical requests are stuck
behind requests to slow storage
•
Individual queues are coalesced
for latency not overall bandwidth
Current queuing mechanisms are
optimized for throughput, not
latency
•
Queue associations are made
from OneCommand Manager

Emulex CrossLink™
SSD Isolation
Challenge
•
Flash requires coordination between nodes
•
Current solutions (TCP/IP and UDP) suffer from
“roundabout” stack-hopping
•
•
•

SSD Coordination
Solution
•
In-band FC Messaging solves
latency & “stack-hopping” for
cache or device coordination
Latency & QoS issues over Ethernet hamper
coordination with storage devices
•
Uses standard & proven FC-CT
protocol for FC and FCoE
Trust issues (storage networks deemed
implicitly secure)
•
Simple interface- kernel or API
Separate Ethernet connectivity requires
additional wiring & management

Emulex & Brocade ClearLink (D_Port) Support
ClearLink is a rich SAN diagnostic mode from
Brocade Gen 5 FC switches (16GFC)
ClearLink is now supported by all 16G (only) host-based Emulex
LightPulse Gen 5 FC HBAs (XE201 based)
Identifies and isolates marginal link level failures and performance issues:
SFP, port, & cable
Emulex # 1 Gen 5 HBAs + Brocade #1 Gen 5 switches,
Together Providing Superior SAN-wide Diagnostics

ClearLink D_Port
Saves Time & Money Troubleshooting
A cable is faulty, but
how do you find it?
Can be hundreds of
cables & SFPs in the
SAN. You could start
replacing
cables and
SFPs, one by one
using trial & error
 Wastes time
– Or replace all
cables and SFPs
in the environment
and try again
 Expensive &
wastes time

Skyhawk RoCE
What is Remote Direct
Memory Management
(RDMA)?
What is RDMA over
Converged Ethernet
(RoCE)?
Benefits of Skyhawk-R
with RoCE

Ability to remotely manage memory enabling server to server data
movement directly between application memory without any CPU
involvement

A mechanism to provide this efficient data transfer with very low
latencies on Ethernet
Basically IB Over Ethernet (with PFC, etc.)
Classic Ethernet is a Best Effort Protocol



Delivers low latency for performance-critical and transaction intensive
applications

Better OPEX vs. Infiniband infrastructure which is requires a unique
fabric which is difficult to deploy and manage
RoCE is IB Over Existing Network Infrastructure

Where to use RDMA
Initial Applications:
– Windows 2012 SMB/Direct
• Which implies SQL/Server, Hyper-V VM migration etc.
– Linux NFS/RDMA
Microsoft will actively market Windows R2 and SMB/Direct
– Better CPU efficiency, faster VM migrations, etc.
– Convince the E/U they need or might want the option
Others will be added in the future
– Based on OEM, Partners and E/U requests and appropriate business
case
