This year, our summer project planning has been influenced
by three independent studies of our Network Services function. These
studies focused on “best practices” related to setting
up our network/server infrastructure, VOIP readiness, and Exchange
Server configuration. A larger than normal carryover of technology
capital funds will be used to resource initiatives 1 and 2 over
the summer.
- Server Upgrades/Reconfiguration (est. $60,000)
This initiative will upgrade the College to Exchange
2007, provide a new full-featured web email interface, and will
address server latency issues.
- Hub/Backend Servers: Replace
Hub and backend servers. Hub server
is identified as a primary reason for email
server delays and all servers need to be
upgraded in order to transition to the new
Exchange 2007 software.
- McAfee Server: One
backend server will be reused as our McAfee ePO server to push
updates to client computers.
- SUS/DNS Server: Second
backend server will be reused as DNS and
SUS server and configured appropriately. The
SUS server pushed various software updates
to client computers and the DNS server provides
internet addressing resolution facilitating
network communications in/out of campus.
- Cached Mode: Deploy this configuration across
all campus computers to better manage Exchange server communications
with clients.
- Network Core Upgrades/Reconfiguration (est. $100,000)
Will address network latency issues, provide network
redundancy, and establish quality of service to streamline and
prioritize network traffic.
- Network Redundancy: Provide
network redundancy in three core closet locations via multi-link
trunking (or similar technology) to eliminate points of failure.
- Quality of Service/VLAN’s:Set
up QOS and multicast on network backbone
to ensure adequate internal bandwidth for
VOIP, email, wireless, video streaming,
and videoconferencing. Establish
new VLAN’s with 24-bit subnet masks
to reduce excessive broadcast traffic and
move CallPilot and signaling server for
VOIP to separate VLAN.
- Network Hops:Eliminate excessive network
hops to establish more efficient network traffic flow
- Security:Provide stable core that enables
secure wireless and network admission control to secure our
network against attacks and intrusion potential introduced
by a wireless implementation.
- Hardware:Purchase and install enterprise
aggregation switches in three core fiber points with new VLAN/QOS
configurations
- Major Security and Application Software Upgrades -
McAfee and Office 2007 (est. $4,000 annual savings)
Based on recommendations, we will transition to McAfee
Enterprise Security Suite and include this rollout with our Office
2007 upgrade
- Security Coverage: Will
include protection at the desktop, file server,
e-mail server and Internet gateway network
levels. Symantec is generating
errors at the server level and does not have
Internet gateway level protection like McAfee.
- Pricing: Annual cost will
be reduced by about $4,000 over our current Symantec solution
by using KY-COT pricing
- Spyware: McAfee includes
full enterprise spyware solution
- Hardware Resources: New
McAfee security product will run more efficiently on client
computers however ram upgrades will be performed for Office
2007.
- Intra-organizational Encryption: All
email passed through our internal network
will be encrypted with Exchange 2007.
- Virtual Learning Community (Faculty/Staff/Student Web
Portals)
- Faculty/Staff/Student Portals: Faculty,
Student, & Staff portals will rollout 10 months earlier
than originally planned. Luminis will deliver our “virtual
learning community” which will include work flow, self-service,
and dashboard elements to individuals based on roles established
in the system.
- Will include latest version 4.0 (not 3.3 as originally
planned) 4.0 was released in March.
- Will include base shells for faculty, staff, and student
portals
- Will incorporate Bond self-service features in our initial
release
- Labor Time Entry: Will include labor
time-entry features (we are now live with four departments
on time-entry using Luminis 3.3)
- Password Complexity Conversion: Establish
Password Complexity in Active
Directory for single sign-on capability
- Labor Program
- Time Entry: Continuing
live rollout of system through the summer
- Portal: Will roll out Labor
Program portal presence in Fall, 2007
- Student Evaluation Form: Will
incorporate in portal presence
- Standardized Classroom Technology
We are standardizing classroom media technologies
around Crestron systems. Installations at the Trustees
Room (Seabury Center) and Instructional Technology Classroom (Hutchins
Library) are now underway.
- Faculty Training: Faculty will be trained
on the new system in the Instructional Technology Classroom
before it is rolled out incrementally to other classrooms on
campus
- Centralized Management: The new system
provides remote management capabilities. This means that anything
the user can do at the console, Media Services can do remotely. This
will expedite assistance and support to those using these
systems.
- Preventative Measures: We can remotely track
error conditions such as when bulbs burn out or reach the end
of their useful life.
- Laptop Integration: The new system
will allow faculty to use their laptops to control any classroom
with a touch panel interface.
- Security: System will notify Media Services/Security
for tamper prevention.
- Media Projects
- President’s Home Intercom System: Recommended
solution was sent to Facilities Management
- Trustees Room: New Crestron
media management solution will be installed
- Instructional Technology Classroom: New
Crestron media management solution will be installed and we
will use the facility to train faculty on use of this instructional
technology control system before we implement it in additional
classrooms.
- Commencement: Support and
video these activities
- Wireless Site Survey
Wireless site surveys will be performed
over the summer with implementation of a campus-wide
wireless solution to be planned in the upcoming
academic year. As wireless access is rolled
out campus-wide, clean access (or a similar product)
will be implemented to control network admission
and reduce internal threats including the connection
of rogue wireless devices on the network.
- Network
Monitoring
IS&S recently purchased a NETMON network device
which will provide dashboard capability to
monitor servers and network devices. This will be implemented
over the summer.
- Renovation Projects
- Haaga House: We are on schedule for VOIP
rollout. Copper cabling is being run for emergency phones
and we are setting up a media room in this facility.
- Middletown: Direct point
to point wireless installed. We are on schedule for VOIP
implementation.
- Elizabeth Rogers and Emery: We are working
with architects now on communications infrastructure planning
based on new IS&S specifications.
- Boone Tavern: We will need to meet to discuss
planning for network/voice communications systems. We
are completing over the summer the transition to new DSL service.
- Fill Vacant Position
Current thinking is to hire a senior
server analyst and perform minor restructuring. I
am working in tandem now with Mike and Kevin
and will have an organization plan in a few weeks.
- Dashboard
Systems
The activities planned
below will lay the foundation for
intensive technical work on Dashboard
systems to take place in Fall, 2008.
- Summer 2007 (Continue Prep Work):
- Continue discussions with SCT on Cognos through the summer
- Set up on-site demos with three vendors to take place
in Fall, 2007
- Analyze pros/cons of using an SCT supported application
or another industry standard solution
- Evaluate pricing of different solutions
- Work with V.P.’s on selection of benchmark measures
- Fall, 2007 (Luminis Rollout)
- Luminis will be the base system that delivers future dashboard
features based on staff roles
- Spring, 2008 (Release implementation of Banner 8.0)
- Fall, 2008 (Technical work on Dashboard systems proceeds)
- Integrated Web Presence for Admissions
We are working with Admissions staff on a new integrated
solution to strengthen web communications with prospective students. Hobson’s
products are in the forefront at this time.
- Projects Continuing Into the Next Academic Year
- Server Room Electric Upgrade with Generator: This
project was funded by the AC but may not move forward until
Fall, 2007 due to summer project schedule. This includes
backup generator, new electrical circuits and a reconfiguration
of the server room layout.
- Backup Process: Establish new server/client
backup processes that include offsite storage through secured
KPEN connection.
- Door Lock Security System: New BASIS security
system to be installed in Computer Center. IS&S staff
will use Employee ID cards to gain access.
- MFD Project: We are working with Printing
Services to upgrade our copiers to network multi-function devices.
- Interasys and BPS2000 Switches: Will
be replaced in the 2007/2008 academic year.
- Converged Messaging: Callpilot converged
messaging will continue to be rolled out so that both email
and voicemail may be managed in the Outlook email client.
- Firewall: We will move to a new ASA device
which is a new generation product that will provide adaptive
security.
Appendix
A—Results
of CBTS (Network/Server Infrastructure) and E&H (VOIP Readiness)
Studies.
Report
from third study on Exchange Server configuration will be delivered
shortly.
Primary Recommendations
- Voice Over IP (E&H)
Challenge: Two mission-critical installations
of VOIP including the Haaga House (Admissions) and Middletown
School (Gear up) will take place over the summer. However,
phone service quality during our pilot testing has continued
to be substandard and packet tracing indicates that many
VOIP calls would be dropped after midnight when server backups
commence. In addition, the BPS 2000 switch used by
the signaling server was configured improperly as an access
port with three VLANS on the port. This configuration
error caused the port to be 95% utilized by broadcast traffic
making it almost unavailable for voice traffic.
Corrective Actions: Both the signaling
server and callpilot servers will be moved to a separate
VLAN and updates will be made to the Signaling Server IP
Address and S1 & S2 addresses on the phone. Second,
we will configure all pass through devices to support QOS
differentiated services code point 40 and 46. These
are standard VOIP settings that will prioritize voice traffic
over data traffic. Third, the configuration error on
the BPS2000 switch has been corrected. All three steps
will improve the quality of VOIP telephone connections to
adequate levels and allow us to move forward with this rollout
of VOIP.
- Network Delays (E&H)
Challenge: The campus is experiencing
some network delays in connecting to various servers (such
as the email server) and when running nightly backups. Berea
has seven VLANS that have a 15 bit subnet mask in their IP
Address configuration and that allows over 131,000
addresses in each broadcast domain. As a result, 50%
of the traffic on the Administrative VLAN is excessive broadcast
traffic. The current configuration allows for 131,171
devices per subnet. This size subnet would support
a large city per VLAN and this is the reason broadcast traffic
is bogging down network access to our servers.
Corrective Action: Over the summer, new
VLANS will be established across the board and will be
configured with a 24 bit subnet mask which limits each
VLAN to 254 devices. We will also reduce the number
of switch hops in some cases to expedite data traffic and
we will increase the number of VLANS to ensure subnets
are smaller. The Nortel 8600 will be upgraded to
support new 8600 interface modules which will allow us
to move servers to a core switch and eliminate a switch
hop for data.
- Network Redundancy (E&H)
Challenge:Our current
router configuration allows for three points of failure that
would bring down substantial portions of our network. Just
one router component failure at any of these points can bring
down a significant segment or the entire network for at least
a day or more.
Corrective Action: We will configure multi-link
trunking on pass-through devices throughout next year to
provide redundant pathways for communication between switches
and routers using our existing fiber backbone. This
will also speed up our network due to these redundant pathways. The
BPS2000 MDA will also be upgraded to support gigabit connections
to the 8600 and to utilize multi-link trunking.
- Server Backups (CBTS)
Challenge: The capacity of our NAS devices is insufficient
to handle current/future server backup needs. In addition,
an industry standard enterprise level backup software solution
is needed to replace our NT Backup solution.
Recommendation: It is recommended that
an off site storage solution is used for some critical data backups. This
will free up capacity on our current NAS devices. In addition,
it is recommended that we replace the disparate Snap Servers
and the NT Backup solution with an appropriately sized redundant
Storage Area Network (SAN).
- Rogue Devices Connected to our Network (CBTS):
Challenge: Our current network configuration
allows free access for students to connect network devices
that jeopardize system security and reliability. CBTS
used network monitoring utilities to identify more than 80
such devices connected to our network. This includes
primarily wireless routers that open our network to others
in a non-secured fashion. Students could be using
college network resources to create private networks for steaming
media, file sharing and gaming blocks. In particular,
several Windows Media and iTunes libraries are being shared
on our network.
Recommendation: IS&S will be implementing
a solution using Clean Access (or similar application) with
MAC Authentication and Certificates to disable these rogue
devices from being used on our network. We hope to have
this solution in place before students return in fall. This
would also provide an option for blacklisting MACS and rogue
Wireless Access Points.
- Other Observations and Suggestions
Below are observations and recommendations quoted
from the detailed reports that cover a range of items studied.
- Domain Controllers: “For
security purposes we recommend applying service pack 2 and
any subsequent critical security patches”
- Network Management: “Current
configuration requires more maintenance and changes than normal
networks we have encountered”. IS&S is purchasing
a new monitoring device and will do several network reconfigurations
to simplify network monitoring and management.
- Internet Pipe: “Seems adequate for
future growth” This recommendation refers to our
current ability under the KPEN solution to expand bandwidth
to the campus as needed.
- Active Directory: “A total of three
domain controllers host the 2400+ accounts that reside on the
Berea.edu domain. We found this to be adequate.”
- ISP: “We found no ISP monitoring or
proactive alarm type service” We are checking into
this.
- Cabling and Physical Topology: “is
adequate for current usage and should be fine for future anticipated
use”
- Switches: “There are a few daisy chained
switches. As reconstruction and dorm upgrades continue,
we suggest that these be eliminated”.
- Firewall: “We recommend replacing
the PIX with a new ASA Cisco Firewall and Cisco’s Clean
Access”. It was suggested that we consider this
in the upcoming year as new Firewall products roll out and
support of our existing solution winds down.
- Packateer: “We found the Packateer
product to be performing adequate Layer 7 filtering for monitoring
and bandwidth shaping. The device does not address the
problematic LAN traffic that peaks and stresses the internal
network. We recommend QOS on the internal network in
the future”. This will be addressed as part of
item 1 above.
- Maintenance Contract and Support: It was
recommended that we put some of the core routers on maintenance
contracts unless we have adequate supplies on hand to replace
failed components. We are evaluating our current maintenance
contract with Pomeroy.
- Virtual Local Area Network: “The VLAN
scheme is overly complicated for an institution the size of
the college. There are too many subnets and too many
hosts in each VLAN”. Corrective actions are described
in item two above.
- Core Routers: “There are currently
three core routers. This could easily be reduced to one
core router with a backup for network redundancy. Currently
a failure at any of the three core routers would cause a substantial
network outage”. This will be addressed in item
three above.
- Wireless: “We recommend a new
wireless network with central management and support teamed
with a Clean Access type product”
- Virus Protection: “With recent issues
exposed by the Symantec Spybot Worm which used the AV product
itself to propagate the worm, we suggest migrating away from
that product” Berea is considering McAffee as an
alternative.
- Remote Access: “A new Cisco ASA with
Clean Access would make the VPN even more manageable and secure”
- Windows Patch Management: “Windows
Patch Management is currently using WSUS 2.0. We suggest
evaluating Enteo NetInstall. Add reminder to check WSUS
on the second Wednesday of every month”
- Passwords: “Get passwords out of .doc
file and set up regular user accounts for admins for testing
(i.e. Mturner and turnerm).”
- Server Room Electrical Generator: It
was agreed by all parties that this project will protect server
assets and data in the event of an extended electrical failure. This
project has been funded by the AC.
- Facilities (Server Room, Switch Closets, Telecommunications
Switch Room)
- Replace great stuff insulation with Hilti Firestop Products
- Install static free tile floors where possible
- Use small IDF containers where appropriate
- Add environmental controls to include AC/Humidity Control/Central
Management/Monitoring of equipment in switch closets.
- Install lighting in some IDF’s
- Some racks in the server room need to be grounded. This
should be done when the redesign of the server room layout
is performed
- Cabling: “Overall, the cabling is
in good shape and most importantly functional. Recommend
that all IDFs be brought into BCSI standards including replacing
metal bread ties with Velcro or zip ties; all rooms be labeled
in a standard fashion; fiber optics need to have covers implemented
for physical eye protection.”
- Callpilot Converged Messaging: The
corrective actions taken in item one above should address problems
we have experienced with Callpilot during our pilot testing
of this product. This includes software delays and freeze
ups.
- Active Directory and Exchange Environments: “meet
the needs of the college. We suggest that the IT department
create an account for Technology Email to be shared by the
department for vendor, product and technology updates and newsletters. We
recommend that all products and software be registered to a
central College Account instead of individual users. Lastly,
administrators should utilize the calendar feature for IT Maintenance
(i.e. WSUS Review).”
Appendix B – Instructional Technology Update
Report prepared by Don Hodges on 5-17-07.
Expansion of survey/remote devices across the curriculum
We have provided remote polling devices in the hands of several
academic departments for use within their courses as a means of
obtaining instant student feedback concerning course content and
providing learner directed feedback to students. These departments
are Economics, Nursing, Physical Education and Health, and Child
and Family Studies. In the future, we hope to expand the
device usage in the Developmental Math department and the Sciences.
Faculty who are using these devices have reported a great deal
of success in integrating them into their pedagogy. Furthermore,
students have been excited to use these devices and have requested
that the faculty use them on a continual basis. One faculty
member, uses the devices every Friday as a review/quiz tool at
the request of her students.
ITRC Support of Academic Documentaries.
The ITRC has provided support for faculty to integrate student
created documentary projects into their courses successfully. We
have worked with 4 classes in the departments of Appalachian
Studies, General Studies, and Theatre to allow their students
to create documentaries. This trend for faculty to
use documentaries instead of written papers to cover historical
topics will continue to increase and will influence Instructional
Technology development in the future. We envision assisting
one class per semester in the area of student created documentaries. We
begin working with the faculty prior to the start of the semester
to refine the course syllabus, course schedule, and project milestones. The
faculty we have worked with are Dr. Martha Beagle, Dr. Chad Berry,
Dr. Meta Mendel-Reyes, and Dr. Rodney Clark.
Last summer we upgraded the ITRC with high end Lenovo notebooks
which have been very successful in providing the level of computing
power needed for the ITRC projects. The Lenovo notebooks
were purchased using IBM grant funds.
Nursing PDA/Pepid Pilot Project
We have worked with the Nursing department for a second year to
develop the PDA Project. This project is currently ongoing
and will be funded by IS&S for one final year. I am
also working with PEPID to provide more in-depth training for
the faculty in order for them to continue to integrate the PDA’s
into their clinical settings.
Examples of these documentaries can be viewed online.
Pilot online IEQ Project
Beginning in the Fall, I worked with Institutional Research to
find a possible software package that would allow them to move
the IEQ process into an online web process. After reviewing
several different enterprise level packages, the decision was
made to pilot an offsite package provided by Online Course Evaluations/Gap
Technologies, Inc. The online IEQ system is currently being
used by several tenured faculty members through the end of the
Spring semester. During the summer, the pilot will be evaluated
by the Institutional Research department and assessed to see
if the Online Course Evaluation system will be used to replace
the written IEQ process starting Fall 2007
Library CALEA Assessment
I worked with Anne Chase to assess the libraries effect on our
network’s CALEA status. The FCC has chosen not to extend
the CALEA requirement to libraries that "acquire broadband
Internet access from a facilities-based provider to enable patrons
or customers to access the Internet". (ARL, 2007). The
facilities based provider includes a commercial ISP, state,
local, or higher education provided ISP (ARL, 2007).
Based on all available information, it is the position of Hutchins
Library and IS&S that internet access through computers located
within Hutchins Library are exempt from CALEA regulations at this
time and do not pose a threat to Berea College's current private
network status. The computers located in Hutchins Library
are primarily located in two areas. One area serves as the "card
catalog" system BANC which allows patrons to access the database
of books and resources provided by the library. The second
area is located within the Reference area and provides patrons
access to online resources needed to conduct research via electronic
services provided by Hutchins Library. While web browsing
access is available on these computers, the primary function of
these computers are for locating and utilizing library resources. There
is minimal traffic in these areas of outside members using the
computers for simple web browsing. The majority of patrons
who use the computer resources of Hutchins Library are engaged
in academic related matters.
Learning Commons Classroom
We are continuing to rotate different technologies in and out of
the Learning Commons Classroom which will have impact on future
classroom deployment. This project is always ongoing.
Blackboard Update
When I updated you at the end of Spring 2006 we had 19 faculty
who were using Bb on enhance their courses.. I did a count
this afternoon and we now have a total of 83 faculty members
who are using Bb in some fashion for a total net gain of 64 faculty
members. The usage varies but includes teaching common
courses (such as GSTR 310 with other faculty members teaching
common content) teaching team taught courses, participating in
faculty groups, and normal online enhanced courses).
Blackboard Backup Server
This is ongoing and should be up and running through the summer.
