We have been engaged by a research hospital to help upgrade their Isilon installation. They currently have 12 previous generation Isilon nodes with 200 TB of capacity and run on a 1 Gbps network.
They currently have 6 Illumina Hi-Seq Sequencers and an HPC cluster to process data. They would like to expand Isilon to 2 PB of active data and 1 PB of archive data. They use a third party data and metadata management service (IRODs) to stage data for analysis. The Isilon cluster is mainly used for analysis work with the HPC cluster.
The customer will add two more Illumina Hi-Seq Sequencers in the next 6 months. Once these are added, what is the total amount of data from all the sequencers they can expect to add per month?
- A . 9.6 TB
- B . 4.8 TB
- C . 1.2 TB
- D . 14.4 TB
How does the Job Engine contribute to workload management?
- A . By distributing and scheduling background cluster jobs to avoid production performance impact
- B . By automatically upgrading OneFS nodes during workload spikes
- C . By replicating all cluster data to offsite backup servers
- D . By encrypting traffic between nodes
What is the key design consideration when selecting switches for a PowerScale environment?
- A . Switches must support the same RAID level as the cluster
- B . Switches must support the required port density, bandwidth, and failover features for node interconnects
- C . Switches should be capable of executing isi statistics commands
- D . Switches must provide built-in cloud tiering support for CloudPools
Refer to the exhibit.
During a requirements gathering meeting, the customer identified a desire to use a codec for editing content that will take up the least amount of space on their Isilon cluster. The content is 1920×1080 HD.
