A cluster has user quotas configured for user's home directories with hard limits and advisory limits set. What would the default setting be for calculating user quotas on the cluster?
An Isilon has two ports configured per node. Each port is on a different VLAN. Although incoming traffic is evenly distributed, transmitted data from the Isilon uses one port more than the other port. What could be the cause of this imbalance?
An existing customer has two NAS systems providing NFS storage in their main datacenter - one is an Isilon cluster and the second is an array from another vendor. Both systems are four years old, and the customer would like to consolidate the storage into a single solution. According to the customer, both systems support identical workloads with similar performance and utilization, and they want the new solution to support 50% performance growth.
Which method can model the workload requirements, and what multiplier will capture the requirements for the new solution?
Your customer uses an existing Isilon cluster consisting of five NL-Series nodes to source broadcast media files for playback and streaming.The customer reports that the playback pauses and stutters regularly. It has been confirmed that there are no network or playback system issues.
Which of the choices listed is the appropriate choice to address the playback issues?
Your customer is looking for a storage solution that will be able to store seven million 3 MB files, which are written and seldom accessed. Read and write operations are both completed by a web-based application, which requires 1.3 Gbps throughput. The customer's network has not been upgraded in many years, so the network interfaces are 1Gbps.
Which cluster configuration would best meet the customer's requirements?
