The hype surrounding data center network convergence and the battle between FCoE vs. iSCSI can obscure the core issue: At the end of the day all storage will traverse the production Ethernet network and engineers must be prepared for this transition
For Ramsey, iSCSI was never a viable option because of Wellmont’s high-performance requirements. “We played around with iSCSI, but that was still going to run over TCP, and you’re still going to contend with buffering, flow control, windowing or packet drops and queuing, so we stayed away from it. What FCoE brings to the table—It doesn’t run over Layer 3. It’s an encapsulation of your Fibre Channel packet inside a native Layer 2 frame, and all we’re doing is transporting
that between the server and up to the Nexus 2232 and the Nexus 5020.”

The MATE software helped Global Crossing transition from overprovisioning bandwidth to precisely targeting capacity increases only where needed.
PLNOG 8: Ivan Pepelnjak - Data Center Fabrics - What Really Matters PROIDEA
The document discusses data center fabric architectures. It describes how traditional data center designs focus on north-south traffic but modern applications generate more east-west traffic between servers. New fabric architectures are needed to provide flexible workload placement and mobility. Common fabric approaches use leaf-spine Clos network designs with non-blocking switching fabrics to provide any-to-any connectivity between endpoints. Large-scale fabrics can be built today using existing switching equipment and protocols like ECMP routing rather than new technologies. The key is to keep layer 2 domains small and use overlay encapsulation for virtual networks.

Wellmont Health System's move from NetWare to Windows 2000 Boosts Reliability...Darren Ramsey
The premier healthcare provider in northeast Tennessee and southwest Virginia, Wellmont Health System had a Novell NetWare environment supporting an increasing number of Microsoft® Windows NT® Server 4.0 based application servers, but it was not supporting them very well. Users had frequent problems with logon, accessing resources across the network, and desktop and server crashes—problems that consumed administrative resources. To solve these problems, Wellmont designed and implemented its own migration to Microsoft Windows® 2000 Server and its Active Directory® service. In addition to minimizing network problems, Wellmont found that the migration was straightforward thanks to built-in migration tools in Windows and the healthcare provider’s in-depth testing.

5th LF Energy Power Grid Model Meet-up SlidesDanBrown980551
5th Power Grid Model Meet-up
It is with great pleasure that we extend to you an invitation to the 5th Power Grid Model Meet-up, scheduled for 6th June 2024. This event will adopt a hybrid format, allowing participants to join us either through an online Mircosoft Teams session or in person at TU/e located at Den Dolech 2, Eindhoven, Netherlands. The meet-up will be hosted by Eindhoven University of Technology (TU/e), a research university specializing in engineering science & technology.
Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.
-An opportunity to connect with fellow Power Grid Model enthusiasts and users.

COVER STORY
THE HYPE SURROUNDING data center
network convergence and the battle
between FCoE vs. iSCSI can obscure
the core issue: At the end of the day
all storage will traverse the produc-
tion Ethernet network and engineers
must be prepared for this transition.
Listening to vendor stories can be
mind-numbing since each is choos-
ing its own corner. Cisco Systems
and Brocade lead the FCoE charge.
Meanwhile, Dell tells its customers
that iSCSI over Ethernet is the path
to convergence. Chip vendors like
Intel and network adapter vendors
like QLogic and Emulex are backing
all horses, ready to support whatever
technology an enterprise chooses.
Enterprises must overlook the
vendor hype and instead consider
their existing infrastructure invest-
ments to determine which technolo-
gy to choose. They also must under-
stand that network convergence
may occur in small increments, not
necessarily going beyond the rack
level in the short term.
“Typically [customers] have one
type of convergence in mind when
they come to us, and we have to
open their minds a bit to the fact
that there are many different
options and they aren’t mutually
exclusive,” said Joe Onisick, techni-
cal solutions architect with the data
center practice of a large system
integrator.
WHY MOVE FORWARD
WITH DATA CENTER NETWORK
CONVERGENCE?
With the proliferation of 10 Gigabit
Ethernet (GbE), server virtualization
and other technologies, enterprises
must look seriously at network con-
vergence to control capital and
operational expenses and reduce
complexity.

servers, especially a VMware rack,
you might have 10 copper Gigabit
Ethernet connections and two Fibre
Channel connections to each serv-
er,” said Darren Ramsey, director of
technology for Wellmont Health
System, a Tennessee-based hospital
chain. “If you have 10 servers in that
rack, that’s 120 cables. That’s a lot
to try to work around, a lot of inflexi-
ble copper, lots of heat. Switch ports
aren’t cheap.”
In his data center, Ramsey recent-
ly introduced network convergence
to eight racks of virtualized Dell
servers using Cisco’s Nexus line. He
consolidated 10 NICSs and two host
bus adapters (HBAs) on each server
to two QLogic converged network
adapters (CNAs) that provide dual
10 GbE FCoE links to redundant top-
of-rack Nexus 2232 Fabric Exten-
ders. All eight pairs of Nexus 2232
Fabric Extenders connect upstream
to two redundant Nexus 5020
switches. Storage and data traffic is
converged via FCoE up to the Nexus
5020s. From there, storage traffic
returns to native Fibre Channel and
connects to a pair of Cisco MDS
9506 Director switches on the stor-
age area network (SAN). The pro-
duction data traffic continues up-
stream to Catalyst 6509 switches.
“The FCoE streamlined and down-
sized the number of Fibre Channel
ports we needed since all hosts now
run directly into the Nexus,” Ramsey
said. “We no longer need to tie
directly into the MDS [from the
server]. And it cut down on the
complexity that was in each rack.
And when we went to two 10 Giga-
bit links on each server, that allowed
us to have more virtual machines on
that box.”
CHOOSING A NETWORK
CONVERGENCE TECHNOLOGY:
ISCSI OR FCOE?
FCoE gets all the data center net-
work convergence hype, but many
industry veterans say iSCSI is anoth-
er viable option. As an IP-based
storage networking protocol, iSCSI
can run natively over an Ethernet
network. Most enterprises that use
iSCSI today run the storage protocol
over their own separate networks
because convergence wasn’t an
option on Gigabit Ethernet. But with
10 GbE switches becoming more
affordable, iSCSI-based conver-
gence is becoming more of a reality.
“Certainly iSCSI is the easier tran-
sition [compared to FCoE],” said
storage blogger and IT consultant
Stephen Foskett. “With iSCSI you
don’t have to have data center
bridging, new NICs, new cables or
new switches.”
Ultimately the existing infrastruc-
ture and the storage demands of an
enterprise will govern the choice of
a network convergence path.
“There are very few times where I
will steer a customer down an FCoE
3. route if they don’t all ready have a
Fibre Channel investment,” said
Onisick. “If they have a need for very
high performance and very low
throughput block data, FCoE is a
great way to do it. If they can sus-
tain a little more latency, iSCSI is
fantastic. And if they have no need
for block data, then NAS [network-
attached storage] and NFS [network
file system] is a fantastic option.”
For Ramsey, iSCSI was never a
viable option because of Wellmont’s
high-performance requirements.
“We played around with iSCSI, but
that was still going to run over TCP,
and you’re still going to contend
with buffering, flow control, win-
dowing or packet drops and queu-
ing, so we stayed away from it.
What FCoE brings to the table—It
doesn’t run over Layer 3. It’s an
encapsulation of your Fibre Channel
packet inside a native Layer 2 frame,
and all we’re doing is transporting
that between the server and up to
the Nexus 2232 and the Nexus
5020.”
NETWORK CONVERGENCE:
NEW STRATEGIES
AND CULTURAL CLASHES
With storage and data convergence,
networking pros will have to think
about networking in a new way.
“You have to realize you’re going
to have a lot more traffic and it’s
going to be a lot more sensitive to
latency and it’s going to be incredi-
bly sensitive to availability,” Foskett
said. “You’ve got to make sure the
network doesn’t go down. If you lose
your data center, people cry about it.
If you lose your storage network,
then servers fall over and that’s a
really big difference. ”
What’s more, networking profes-
sionals will need to familiarize
themselves with the management
concerns of storage professionals if
they are going to have storage traffic
on their production networks,
according to Stuart Miniman, princi-
pal research contributor to Wikibon,
an online technology research com-
munity.
“A storage person is really con-
cerned about data availability and
making sure there is never a data
loss, as opposed to a networking
administrator who is really con-
cerned about making sure there is
connectivity, bandwidth and
resiliency,” Miniman said.
These different mindsets have tra-

4. ditionally led to culture clashes
when storage and networking pro-
fessionals work together. Now they
must find common ground.
“We heard that there were a lot of
folks who never do [convergence]
because their network folks and
their SAN folks don’t talk to each
other,” said Bob Cloud, executive
director of IT infrastructure services
at the University of Alabama at
Birmingham. “We’re unique because
our network guys work for me and
our SAN guys work for me.”
Cloud has brought his storage and
networking teams together while
piloting FCoE-based network con-
vergence in his data center. As a
Brocade customer on both the Eth-
ernet and Fibre Channel side of
things, Cloud elected to pilot FCoE
with Brocade’s technology begin-
ning last September.
In one server rack he has intro-
duced two redundant Brocade 8000
top- of -rack switches. The servers
in the rack connect to each switch
via FCoE. The 8000 switches then
use Fibre Channel connections to
send storage traffic to a Brocade
DCX storage director switch and
Ethernet uplinks to send production
data traffic to upstream Brocade
FastIron SuperX switches. At first
the storage and networking teams
were confused about who would
own the Brocade 8000 FCoE
switches.
“I think there was some natural
confusion over who was going to
own the switch and who was going
to name the switch,” Cloud said.
“But we got past that pretty quickly
because in our data center both the
networking group and the SAN
group report to me. I told them to
work it out because it’s a trial. The
purpose of the trial is to uncover the
organizational issues.”
DEFINING MANAGEMENT DUTIES
A common management platform
will be essential to working out
those organizational issues, Cloud
said. Brocade has announced a new
unified management product, Bro-
cade Network Advisor, which sup-
ports management of Fibre Channel,
FCoE, MPLS and IP switching and
routing. Cloud is still waiting for the
product.
“We may always have a route
access level person in the network-
ing group and I think the SAN folks
are fine with that. The networking
group will have a little more authori-
ty over management of the switch
than the SAN folks, but the SAN
folks will have everything they need
to troubleshoot and monitor Fibre
Channel,” he said.
Wellmont’s Ramsey also manages
both the storage and networking
teams in his data center, so he’s
been able to keep his eye on the big
picture. “I’m not going to have any-
one fight over a sandbox,” he said.

He doesn’t see convergence as
being that big a change organiza-
tionally. The Fibre Channel demar-
cation line has been pushed back
from the server to his Nexus 5020
switches, putting that into the net-
working team’s domain, but the
storage guys do everything else in
managing their SAN.
“It’s just that, instead of managing
ports that correspond directly to a
server, now they go to the connec-
tions on the 5020 and it’s all kind of
virtualized. Our SAN guys are more
than welcome to jump in there and
learn [Ethernet], but they are busy
doing what they do—provisioning
storage and making sure that SRDF
[EMC Symmetrix Remote Data
Facility] is working properly. And I
think that they embraced the idea of
getting that extra network burden
off of them,” Ramsey said.
NETWORK CONVERGENCE
BEYOND THE RACK
Although Cisco and other vendors
will begin delivery of end-to-end
FCoE switching capabilities this
year, with technologies like Shortest
Path Bridging and Transparent Inter-
connection of Lots of Links (TRILL),
Ramsey doesn’t see moving beyond
rack-level network convergence
within the next five years.
“What you’re talking about is
multi-hop FCoE, and Cisco is still
working on fleshing that out. The
most bang for the buck right now
is to simplify the rack environment.
If you want to go all FCoE, all your
EMC stuff is going to have to be
retrofitted with FCoE 10 Gigabit.
And at that point you could proba-
bly get rid of your Fibre Channel.
Maybe in five years we’ll look at
that, but that’s not really going to
buy us anything right now. We’re
just not pushing into the type of
bandwidth where we would need
dedicated 10 Gigabit to the storage.
We don’t need that much data.
Where FCoE helps us is simplifica-
tion inside the rack, making it faster,
cheaper and smaller.”
Cloud is also not ready to look
past the rack until he gets a better
handle on management of con-
verged networks.
“[Brocade] just announced a lot
of this stuff, and we want to test out
the management system. Once we
prove that out, we’ll be looking to go
further [with convergence]. We are
trying to figure out the total cost of
ownership.”■
