NVMe over Fibre Channel is relatively new, even thought its
component parts are not!
Gen 6 and Gen 7 support FC-NVMe
• Fibre Channel has been the leading enterprise storage technology since the
mid-1990’s
• Speeds of 16Gbps (GEN 5) and 32Gbps (GEN 6) are widespread.
• Gen 6 (2016), delivering twice the speed of GEN 5… Again, IBM and
Brocade announced GEN5 SAN EOL.
• GEN 7, which will double the speeds yet again, is already here!.

• You can deploy NVMe over Fibre Channel on an existing Brocade FC
infrastructure, providing it is relatively up to date!

Why NVMe? What makes NVMe So Fast?
Instead of SCSI’s single command queue
(with a depth of 32 commands),
NVMe supports 65K queues with 65K
SCSI NVMe commands per queue, which means that a
far greater number of commands can be
executed simultaneously.

Best Practices…Dual-protocol infrastructure (Recommended)
Servers
• Deploy NVMe based arrays SCSI-on-FC
– Leverage existing SAN infrastructure FC-NVMe GEN6 HBAs
– Easily supported dual infrastructure
– How long will the transition take?
– Avoid risks
• Incremental Migration
– Applications dictate how individual volumes can
be migrated
– Changes can be rolled back easily without
DUAL Protocol SAN arrays Existing 32Gb FC fabric
disruption to hardware or cabling
Existing enterprise SCSI-on-FC
• FCP & NVMe over FC can both leverage FC Storage infrastructure FC-NVME
zoning
– Only SAN Zoning improves security
– Zoning restricts devices from accessing
network areas that should not be visiting!
• Discovery
– Emulex create drivers that leverage FCP for SCSI on FC Arrays FC NVMe Arrays

FC-NVMe traffic support
© Copyright IBM Corporation 2021Where to start? The Lab!
• Steps to establish a FC-NVMe test lab. Servers
SCSI-on-FC
FC-NVMe GEN6 HBAs
– Set up a single server with an internal
drive, single switch, and a single
FC-NVMe enabled array
– Connect the server to an IP network
for access to other servers.
– Explore the HBA config and storage array
options you’ve read so much about! DUAL Protocol SAN arrays Existing 32Gb FC fabric
Existing enterprise SCSI-on-FC
– Configure a volume to use the NVMe array
Storage infrastructure FC-NVME
– Copy a file from the internal drive to the NVMe
volume and back again.
– Run your performance testing application (Iometer)
to benchmark your NVMe volume. Compare it to
your internal volume.

© Copyright IBM Corporation 2021Ten NVMe over Fibre Channel Takeaways
1. Reduce risk to business operations by extending the existing SCSI/FC network to
include NVMe/FC
2. Improve server CPU utilization and ROI with NVMe/FC.
3. Drive more application workload because NVMe’s input/ output operations per
second (IOPS) will have as much impact as its latency.
4. Install NVMe-ready devices today to allow applications to exploit the next generation
of low latency flash — Storage Class Memory
5. Leverage the multiple NVMe flash media form factors to cost optimize your IT
infrastructure
6. Allow the NVMe future to come at its own pace.
7. Include vendor support in your NVMe-FC adoption plan:
8. Fibre Channel (FC) and Ethernet/IP are optimized different
9. Dedicate a separate storage fabric for best results.
10. Maximize your Fibre Channel fabrics and minimize your migration by running both
SCSI/FC (FCP) and FC-NVMe.

server with an Emulex LPe35002 FC host bus adapter
connected through an IBM SAN64B-7 storage network
switch to an IBM FlashSystem 9200
• The storage network was configured with two 32G Fibre
Channel connections between the FlashSystem 9200
and the storage network switch.
• This configuration was zoned to make it easy to compare the
performance of applications that were deployed on different
storage networks (e.g., the latest 32G end-to-end NVMe over
Fabrics versus SCSI over 32G Fibre Channel).

• OLTP Testing and Results
Increasing Oracle OLTP Performance with End-to-End NVMe
• OLTP workload was tested with an Oracle 19c
database and HammerDB
• The HammerDB workload generator emulates the
activity of users in a typical online brokerage firm as Oracle
they generate trades, perform account inquiries, and
execute market research TPM
• The Oracle 19c database was configured with an 8KB +83%
database block size
• OLTP Results
• Oracle was able to sustain 83% more transactions
per minute when running NVME/FC as compared to
traditional SCSI/FC
• Throughput Performance Results Throughput
• NVMe/FC was 79% higher than traditional SCSI/FC MB/s
+79%

• CPU Impact Analysis
• Test Objective
• ESG looked at how NVMe/FC protocol improves the Maximizing CPU Efficiency for Transactions Per Minute (TPM)/ Core
efficiency of CPU and I/O overhead of application
servers
• CPU Efficiency Findings
• The CPU core utilization statistics quantify the
increased CPU utilization when testing NVMe/FC Oracle
• 32G SCSI/FC - 26% per core utilization TPM/Core
• 32G NVMe/FC – 35% per core utilization (+9% increase) +31%
Utilization
• End User Impact
• The small increase (+9%) in system CPU utilization
is more than offset by the increased transaction
processing (+31%)
• Correlating the application-level transactions per
minute with CPU core utilization provides a useful
measure of the I/O CPU efficiency benefits of end-
to-end NVMe for Oracle applications, in this case up
to 31% more TPM per core

• Validation Objective
• Confirm the ease of transition from an existing
SCSI/FC data path to an NVMe/FC data path
• Methodology
• VMware vCenter 7.0 was deployed on an ESXi host
containing multiple virtual machines (VMs) to
datastores loaded onto the IBM FlashSystem 9200
via an NVMe fabric
• The FlashSystem 9200 contained two volumes
• 10GB SCSI/FC disk (containing the “FCP200” datastore)
• 10GB NVMe/FC disk (containing the “NVMe200”
datastore).
• Simulated OLTP-like workload was loaded on
“VM21” with a 70/30 read/write ratio, 32 threads,
queue depth of two, and 4KB I/O size
• Simulated workload was used to characterize
performance before and after application migration Initial Workload & Performance Monitoring
• VM21 was initially connected to the datastore on SCSI/FC datastore – Migrated to NVMe/FC
“FCP200” and migrated to the datastore on datastore

• Problem Statement:
Congestion “Self-Healing” Test Configuration:
• Broadcom customers consistently reported that finding A virtualized x86 server with virtualized applications are driving
and fixing SAN congestion problems is a top SAN workload to the IBM Flashsystems platform through two different
management challenge FC Adapters and a single FC SAN switch
• Validation Objective
• Confirm that Fabric Performance Impact Notification
(FPIN) implementation can provide “Self Healing” of
fabric congestion
• Methodology
• A simple configuration was used with two paths to the
storage controller
• IBM SANnav and Emulex SAN Manager (ESM) mgmt
tools monitored for congestion notification and reaction
• Simulated congestion was introduced into the fabric to Simulated Congestion Introduced:
understand the impact of FPIN and the infrastructure A deliberate speed mismatch between the flash array and
responses server HBAs were used to simulate a congestion slowdown
• Industry-standard FIO benchmark utility was used to for a higher priority data warehouse application after a

• ESG Observations
• SAN congestion was flagged as a problem through the IBM
IBM SANnav Identifying Path Congestion
SANnav as an event that needed investigation.
• IBM SANnav made it easy to visually investigate the error
with a single click to drill down to explore the cause of the
alerts
• IBM b-type switches detected and identified the congestion impact,
the FPIN was sent to the end device, in this case, the Emulex FC HBA.
• Emulex SAN Manager (ESM) visualized the FPIN notifications
sent by b-type switches
• A moderate level of port congestion management was set for
the lower priority application
• This setting tells the Emulex FC HBAs to slow down the lower priority
“bully” traffic and eliminates the port congestion issue through an
automated process
• Client Benefit
• Finding, fixing, and automatically eliminating SAN
congestion problems saves time and money for IT
professionals and improves customer satisfaction and

• The Bigger Truth
• ESG validated that in a virtualized VMware vSphere 7
environment, an IBM FlashSystem 9200 end-to-end 32G
NVMe solution with IBM Gen 7 b-type storage networking and
Gen 7 Emulex FC HBAs:
• Delivered 83% more Oracle OLTP transactions per minute and 79%
higher throughput in a VMware ESXi 7.0 environment compared with
32G SCSI/FC technology
• Provided up to 31% more performance per CPU core for Oracle
databases
• Can help organizations to perform application migrations from
SCSI/FC to NVMe/FC-based storage easily and non-disruptively
• Have leveraged the FPIN specification to automatically find and fix
SAN congestion problems. Detecting and troubleshooting SAN
congestion with IBM SANnav Management Portal and displaying FPIN
notifications with Emulex SAN Manager (ESM) was intuitive and easy
