Hello There,
I have a scenario from my client on which I am seeking for your recommendation and advice as soon as possible. I am really confused on this if DFS on Win2k8R2 is the solution for this?. I have no idea if win2k8 R2 will work with these OS file server and replicate in timely manner and fulfill asked requirements. Thanking you in advance for early response.
Here is the scenario and requirements
SETTING UP A GLOBAL FILE SERVER WITH A HOT DR BACKUP:
XYZ Ltd is a global fund management company with offices in Singapore, Sydney and Malaysia.
Each office has a local file server that would be shut down at the end of the working day thus only accessible at each location’s office hours. As operations become more global, there is a need for a global file server that is accessible 24 / 7. The global
file server has to be able to perform a 2-way synchronisation to ensure the latest copies of files are updated to the global file server and to each local file server at any point in time wherever the file may be updated, either from the global file server
or local file server. A hot backup has to be set up for the global file server so that if the production global file server crashes, the backup can immediately be activated and retrieve the latest, most updated files, with minimum downtime and virtually zero
impact on operations. Users have to be able to continually access their latest working files. Task Assuming each office in Malaysia, Singapore and Australia, has one file server each, the Environment Specification and details for each file server are listed
as follows.
Server A (Malaysia):
OS: FREEBSD 6.1
Applications: OpenLDAP, Samba
Bandwidth: Upstream 512Kbps, Downstream 1 Mbps
Server B (Singapore):
OS: CentOS 5.3
Applications: OpenLDAP, Samba
Bandwidth: Upstream 768Kbps, Downstream 2 Mbps
Server C (Australia):
OS: Windows 2003 Server
Applications: Active Directory, Network FileSharing
Bandwidth: Upstream 1Mbps, Downstream 4 Mbps
Requirements:
1. All servers are hosted locally in the office.
2. Server A and B will start its service from 8:30am to 7:00pm (Malaysian Time).
3. Server C will start its service from 9:00am to 6:00pm (Australian Time).
4. The Marketing Manager and Higher Management will need to access files in these servers at any time and from any where in the world.
5. Files stored in the file servers vary in sizes from 1Kb to 200Mb.
6. All applications, protocols and communications tools must be on open source framework or developed internally.
7. Communication channels between clients and servers must be tightly secured.
8. Any changes to the central server will be automatically copied and thus reflected in the local server.
9. Changes to files must be logged, and can be audited by IT staff.
10. Average file sizes are around 10Mb, must be able to be opened within 1 to 2 minutes.
11. There must be a backup for every file, just in case users accidentally remove the file.
According to the specifications and requirements stated above, you are expected to come up with a working prototype of a system (Global File Server) that can meet the above requirements. Include all relevant network diagrams, UML diagrams and flowcharts in
your answer. List all the applications, protocols and monitoring tools that are used in the system in as much detail as possible. Explain the strengths and weaknesses of the prototype system and how the system can be improved. The system must be accompanied
by a Disaster Recovery plan.
