Question 12: -- Exhibit --A large manufacturing company is an existing Isilon customer with a cluster consisting of four NL400
nodes with 4TB drives. The cluster is using N+2:1 protection level and the file system shows that it is
60% utilized. Home directories and file shares comprise 75% of the existing content and the
remainder is inactive deep archive. The company has 1,000 employees using Windows and Mac
clients participating in a single Active Directory (AD) forest.
During a meeting with the CIO and Director of IT you discuss the company's recent acquisition - an
engineering firm that specializes in Computer Aided Design (CAD). The engineering firm has 400 UNIX
workstations that produce technical drawings which are currently stored on another vendor's SAN
solution. The all UNIX environment uses NIS for authentication and name resolution. They do not
currently use DNS or LDAP. The engineering company has an old storage system that has been
experiencing problems and the CIO would like you to migrate the data onto the Isilon cluster. The CIO
would like to eliminate all tape and recover the data onto disk.
The CIO is concerned about security of the company's intellectual property, especially with the rapid
adoption of mobile devices and external cloud content sharing services such as DropBox, Egnyte, and
SugarSync. They would like to implement an alternative that provides external file sharing and mobile
device synchronization while maintaining security control over the company's data.
The Director of IT reports that users are storing non-work related content on the Isilon cluster. They
would like to limit the amount of capacity that each user can consume in their home directory and
want to ensure you provide the capability to easily visualize which users are over their allotment.The
company's Windows users currently leverage Windows Shadow Copy to recover files that have been
accidentally deleted. The IT department wants to ensure that Mac and incoming UNIX clients have
the same functionality.
The Director of IT also mentions that users are reporting slow response times when browsing their
home directories and shared folders. They are concerned that Isilon cannot scale to support their
combined requirements.
