A 6 × F800 node Isilon cluster has one subnet with two IP pools with LACP aggregated 10GigE interfaces from

all the nodes in the ‘Data-Zone’ Access Zone. The ‘NFS-Pool’ with dynamic IP Allocation schema and ‘SMBPool’

with static IP Allocation schema are being used.

All the Linux clients are accessing Isilon exports using NFSv3 via the ‘NFS_Pool’. All the Windows clients are

accessing Isilon shares using SMBv3 via the ‘SMB_Pool’.

While deploying Isilon, the customer reserves the whole network subnet for Isilon. The customer is facing

performance issues with a new workload that is accessing the Isilon via Kerberized NFSv4.

What is recommended when creating a new IP pool for NFSv4 clients?

While validating the value (VTV) with a large educational customer, they have decided they would like to add a Disaster Recovery (DR) site to their existing Isilon environment. The existing cluster contains six X-Series nodes. They plan to have all workflows replicated to the DR site and both clusters will have identical shares, exports, and user authentication. The customer would like to test DR failover every six months by running their production environment from the DR site.

What would you recommend for the DR solution?

Your customer is a major metropolitan newspaper. Your previous discussion centered on their storage requirements, and you asked them some of the Top Ten questions.

They responded: "Well, it's not the prettiest or most high-tech solution...we use Secure FTP (SFTP) to upload the stories and images and put them in a workflow that formats them for printing in the newspaper." "What really worries us is the fact that our Storage Array from your competitor is going out of maintenance in 120 days, and they are dropping support for Secure FTP. This isn't even considered in our D/R Plan. Do you have a better solution with Isilon?"

-- 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.
