There is a concern that there are not enough physical switch ports available for the Isilon cluster in a new implementation with SMB and ICAP requirements.
What course of action should be taken?
- A . Team the NICs across the nodes and just add one connection to minimize the ports required.
- B . The customer needs to provide more switch ports for the implementation
- C . Create a SmartConnect zone across all ports but do not connect all of them

A company currently has multiple fileservers to provide home directories for its employees. Each department has a separate fileserver.
Most corporate users are on Windows clients and utilize Active Directory, except for the Engineering department, which uses Linux and NIS for authentication. The company is looking for a solution with minimal administrative overhead and a single namespace for the home directories.
What is the recommended solution that will meet this company’s requirements?
- A . Configure a single Isilon cluster and utilize Access Zones for authentication to Active Directory and NIS.
- B . Configure two separate clusters, one for Windows clients and the other for Linux.
- C . Utilize SmartPools to create two different FilePools, and separate Windows users from Linux users.
- D . Configure a single cluster, and migrate Linux users to Windows.

- B . Endurant Cache waits for acknowledgement from all nodes before copying to L2 cache
- C . SmartCache immediately commits the write to NVRAM on the local node and one peer node
- D . SmartCache uses sub-file, granular locking whereas Endurant Cache locks the entire file
