The purpose of this document is to serve as a basis for discussion of the setup of the PCs in GITC 4111.

1. General configuration and requirements
1. The PCs in GITC 4111 will be used by the research group to form an Hadoop cluster
2. All PCs will run Scientific Linux 7
3. sudo rights given as needed
4. All PCs will have access to MS Windows services
5. All PCs wil be managed by Academic and Research Computing Systems (ARCS)




2. Windows services

These services can be provided in the following ways.

1. A VM in the IST datacenter
1. Provides Windows desktop on all PCs
2. Managed by IST - patched, secure, backed up, automatic failover if hardware problem
3. Software installed upon request
4. Expandable
2. VM in Virtual Box on each PC

The Information Services & Technology (IST) policy on Windows PCs in research labs is :

1. The faculty member in charge of the lab will have built-in administrator rights
2. One student in the lab will have local administrator rights
3. Administrator credentials should not be shared with anyone
4. The local administrator's pre-set password cannot be modified
5. A PC may be blocked from the NJIT network if there is a security breach on the PC
6. If there are repeated security breaches, local administrator rights will be removed

ARCS will enforce security settings at the group policy level.

3. Dual boot
1. The OS that is not in use does not get updates
2. High maintenance - requires constant manual intervention
3. Considered the least reliable means of providing both Linux and Windows functionality,/li>




3. Storage
1. Each PC has a 1-TB disk
• Note : option B.2 requires 0.5TB of the local disk
2. The 1-TB disk is not backed up
3. Each PC has access to a shared 500-GB space /afs/cad/research/ccs/chasewu/1/
4. Disks installed in tiger.arcs and rabbit.arcs can be NFS-mounted on each PC




4. Recommendation for Item B.

ARCS strongly recommends option B.1.

1. One environment, not many that will all be different from each other
2. No management by lab personnel
3. Same environment on each PC
   1. PCs are not tied to a particular student
   2. Readily accommodates changing student population
