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.

Wellmont Health System 2004 Enterprise Networks Design AwardDarren Ramsey
When fully operational summer 2004, the new multiservice infrastructure will solve a plethora of business critical issues for Wellmont. Not the least of these is delivering a simplified, all IP-based network with enough bandwidth to easily transport the health care organization’s patient records, as well as dicom images created by the hospital system’s Agfa electronic medical imaging system. The new infrastructure will also add high-availability failover redundancy for disaster recovery between
Wellmont’s three main facilities; Differentiated Services Code Point (DSCP) for end-to-end QoS; and the ability to deploy several bandwidth-intensive applications, including medical imaging, health information systems,VoIP, and an IP SAN that supports both Internet SCSI (iSCSI) and Fibre Channel over IP (FCIP) over the new
backbone. All of this will be carried over three pairs ofleased fiber optic circuits from Sprint, which initially balked when Wellmont inquired about renting its unused
dark fiber capacity.
FCoE or iSCSI doesn't matter, it's about the Ethernet.Darren Ramsey
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.”

[OReilly Superstream] Occupy the Space: A grassroots guide to engineering (an...Jason Yip
The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data

Wellmont Health System's move from NetWare to Windows 2000 Boosts Reliability and Performance, Cuts TCO
1. Move from NetWare to Windows 2000 Boosts
Reliability and Performance, Cuts TCO
Published: July 2002
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.
Situation
Founded in 1996, Wellmont Health System is the premier healthcare provider in northeast
Tennessee and southwest Virginia. The integrated healthcare delivery system consists of five
medical centers and hospitals, 40 clinics, an assisted living center, a hospice, and a wellness
center. Wellmont's broad scope of services ranges from community-based acute care to highly
specialized tertiary services including neonatal intensive care and two trauma centers. Wellmont
is one of the region's largest employers with a staff of 4,500 dedicated professionals. Nearly 600
physicians deliver care at Wellmont facilities.
Wellmont’s technology infrastructure was a mixture of network protocols and directories, including
unmanaged desktops with high total cost of ownership (TCO). The organization had started with
a pure Novell NetWare 4.1 and 5.0 network and then began adding servers running Microsoft®
Windows NT® Server network operating system version 4.0, first to migrate from Lotus cc:Mail to
Microsoft Exchange Server version 5.5 and then to support additional, industry-specific solutions
running on the Microsoft Windows® operating system. Before long, Wellmont had more than 60
Windows NT–based servers.
“The market drove our move to Windows,” says Darren Ramsey, Senior Specialist for
Networking, Wellmont Health System. “From no Windows servers, we quickly went to installing a
Windows server a week to support our growing range of healthcare applications.”
Solution Overview
Customer Profile
Founded in 1996, Wellmont Health
System is the premier healthcare
provider in northeast Tennessee and
southwest Virginia.
Business Situation
Wellmont’s infrastructure was based
on Novell NetWare, with Microsoft®
Windows NT® Server and UNIX.

2. With a mixture of operating systems and directories, Wellmont began to experience password
synchronization problems. Its help desk was flooded with calls from users who couldn’t access
all of their directories, applications, and other network resources such as printers. The
organization tried to solve these problems using Novell’s NDS for Windows NT software. But
user authentication remained spotty, administrators often couldn’t locate user groups, and the
product had scalability issues that made it less than ideal for Wellmont’s more than 3,000 users
and more than 1,000 Windows NT groups. Wellmont decided that NetWare was at the core of its
continuing problem.
Solution
“To solve our problems, we decided to pull out all of the Novell network and move completely to
Microsoft Windows 2000 Server with Active Directory service,” says Ramsey. “We wrote the plan
and did the migration ourselves. The migration went smoothly, and we’re delighted with the
results.”
Wellmont migrated eight NetWare servers—running file, print, Btrieve, Radius, Lightweight
Directory Access Protocol (LDAP), and NDS—to Windows 2000 and upgraded Windows NT
domain controllers to Windows 2000. Now the organization runs 70 servers on a mixture of
Windows NT Server 4.0, Windows 2000 Server with Active Directory, and Windows 2000
Advanced Server, which is used to support clustering and multiprocessor server hardware.
Active Directory replaces NDS to offer a single, unified directory structure and single logon and
password that provide authorized access to both the Windows-based environment and
Wellmont’s remaining legacy applications. Active Directory is also key to Wellmont’s efforts, now
underway, to comply with the U.S. Health Insurance Portability and Accountability Act (HIPAA).
Active Directory serves as a great mechanism for Single Sign-On—to in-house and third-party
applications, network gear, and UNIX applications—to help Wellmont address HIPAA’s security
requirements.
Wellmont now is piloting a desktop move to Windows XP and planning an upgrade to Microsoft
Windows .NET Server and Exchange 2000 Server, which will enable it to gain more granular
control over Active Directory, take advantage of its integration with Exchange 2000, and further
boost reliability, scalability, and performance.
During planning for the migration to Windows 2000 Server and Active Directory, Wellmont put a
premium on minimizing user downtime and the cost of migration. That led to a distinctive
approach in which the Wellmont team—including Ramsey and systems specialists Mickey Locke
and John Wininger—first uninstalled NDS for Windows NT in order to move the Windows NT
security account manager back to the Windows NT primary domain controller. They verified that
user accounts and groups existed in NDS and in the Windows NT domain. Then they moved all
file and print resources from NDS to the Windows 2000 Server infrastructure. With these steps in
place, they implemented the in-place migration from Windows NT Server to Windows 2000
Server.
With the Windows 2000 Server domain established in native mode, the team used a script based
on Active Directory Service Interfaces (ADSI) and LDAP that it had created in the Microsoft Visual
Basic® development system to identify user data from the existing NDS directory database and
populate Active Directory. The process also moved users to containers and organizational
structures in Active Directory that corresponded to their previous status in the NDS infrastructure.
“To solve our problems, we
decided to pull out all of the
Novell network and move
completely to Microsoft
Windows 2000 Server with
Active Directory service….
The migration went
smoothly, and we’re
delighted with the results.”

3. The team practiced the migration many times in a test lab before implementing it in the
production environment. When the migration was complete, Wellmont had an Active Directory
organizational unit structure that exactly mirrored its former NDS structure.
“We found that the tools that Microsoft provides in Windows for in-place migration, combined
with the script we created in Visual Basic, enabled us to implement the migration to Windows
2000 Server and Active Directory without any major downtime or problems,” says Ramsey. “We
tested the migration until we were confident it would work successfully. So when we did it for
real, it was very easy. We did it ourselves and potentially saved up to a million dollars on outside
vendors and third-party migration tools.”
Benefits
Greater Performance and Reliability Please Users, Administrators
Speed on the Wellmont’s desktops immediately jumped by 20 to 40 percent, and processor
utilization on some networking gear dropped by up to 15 percent, as soon as the team took the
NetWare clients off its PCs and replaced the NetWare Internetwork Packet Exchange (IPX)
protocol with the Windows Internet Protocol (IP). The team also found that the migration
eliminated 150 KB of unwanted IPX, Routing Information Protocol (RIP), and Service Advertising
Protocol (SAP) traffic on the network—not a big deal on 10/100/1000-MB Ethernet and T1
bandwidth lines perhaps, but a significant factor on the 256K lines that Wellmont continues to
use to some outlying facilities. On those lines, the unwanted NetWare administrative traffic had
been consuming the majority of available bandwidth.
“Users were quick to tell us how much faster their PCs ran after the migration to Windows,” says
Ramsey. “From the user perspective, the network probably operated twice as fast as before. And
that’s on top of the greater speed that users saw when they initially logged in—we eliminated a
four- to five-second delay. With Windows, users log in and they’re on the network instantly.”
Along with the greater performance resulting from the switch to Windows from NetWare,
Wellmont is seeing greater reliability. System crashes that came once or twice a month under
NetWare have been eliminated since the move to Windows, according to Ramsey. Trouble calls
on file and print sharing—one of Wellmont’s key problems with NetWare—have plummeted by 95
percent. Issues related to NetWare logon have been eliminated. Availability is expected to get a
further boost when Wellmont completes its migration to Exchange 2000 Server. Because the
software supports clustering, Wellmont should be able to conduct scheduled maintenance and
respond to critical incidents without creating any downtime for users.
Wellmont has implemented Active Directory with a domain controller and global catalog at each
major site, so authentications and other services can be implemented locally, without having to go
over the wide area network. Users benefit both in increased speed and greater reliability.
Streamlined Management Reduces TCO
Much of the reduced TCO that Wellmont enjoys with Windows 2000 Server comes from the
streamlined information technology (IT) management that the Microsoft platform enables. For
example, seven NetWare servers needed for file sharing have been reduced to just two under
Windows 2000 Server. Wellmont saves 70 percent of the cost of maintaining those servers.
Platform consolidation is just one example of Wellmont’s streamlined IT management. With just
one operating system to support, training costs have been slashed by 50 percent. And with a
