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 1 Gbps.
What would be the best solution for this network configuration?
A. Use LACP to aggregate the network ports on each node.
B. Use jumbo frames to compensate for the 1GB Core network.
C. Aggregate Infiniband (IB) ports across all nodes.
D. Bond EXT-0 across all nodes.
Your customer's initial use case was Home Directories. They implemented the cluster with four 1Gbps ports and LACP. They are planning to expand their cluster to support their core file services. They plan to upgrade their network infrastructure to 10 GbE to facilitate this.
What are two design impacts this change will have?
A. Maximum performance is obtained by only using a single 10GbE interface per node. LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system
B. LACP and multiple links may be used to increase redundancy, but will not provide more overall performance to the system. FCoE should be considered for the External Network Ports on the nodes.
C. Dual 10GbE ports on each node will enable throughput of 20Gbps. Only connect half of the nodes to the network.
D. Maximum performance is obtained by only using a single 10GbE interface per node. Isilon can support up to 400MB/s per node
A potential customer requires 800 TB of usable capacity to store medical images for their network of health clinics. The IT department has limited staff and currently manages four storage arrays from other vendors. During a meeting with the Director of IT you learn that the company is considering a solution from a competitor of EMC using two of the existing arrays and two new arrays.
Which Isilon capabilities would show a better ROI for the customer?
A. Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions. With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher. Isilon utilization is typically 80% or higher due to use of a single filesystem and virtual capacity for drive and node failures.
B. With a single filesystem and virtual capacity for drive and node failures, Isilon utilization is typically 80% or higher. OneFS compression results in higher effective capacity within the cluster. Traditional clustered filesystems require 4%-10% internal overhead compared to Isilon virtual capacity.
C. Forward Error Correction overhead is 7% lower than traditional RAID. Isilon has 6%-12% less filesystem overhead than traditional clustered filesystem solutions. According to an IDC study, Isilon improves IT productivity by nearly 50% compared to traditional competitors.
D. Isilon has 15%-20% less overhead than traditional clustered filesystems. According to an IDC study, Isilon utilization is nearly 50% higher than traditional competitors. Isilon QOS headroom and multiple node pools ensures consistent performance up to 80% utilization.
A potential customer requires 4 PB of usable capacity to store media files. The workloads are a combination of streaming video delivery and long term archive of video assets.
There is very little space available in the customer's datacenter, so physical density is very important. The customer is concerned about performance impact and potential data loss when using 3 TB or larger drives.
What Isilon capabilities can address the customer's concerns?
A. Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID rebuilds. N+3 and N+4 Protection Levels exceed traditional RAID6 availability. Data redistribution runs faster with more nodes in the cluster.
B. N+3 and N+4 Protection Levels exceed traditional RAID6 availability. Proactive hot sparing eliminates most drive rebuilds. Endurant Cache reduces the overhead for write operations.
C. Isilon does not perform rebuilds - data reprotection is typically 2x-3x faster than traditional RAID rebuilds. Data recovery is consistent, taking the same amount of time regardless of cluster size. Isilon 'short strokes' 4TB drives to reduce rebuild time.
D. Isilon nodes have more drives per rack unit so fewer shelves are required. Proactive hot sparing eliminates most drive rebuilds. N+3 and N+4 Protection Levels exceed traditional RAID6 availability.
You are asked to size a cluster for a file sharing environment. nfsstat indicates that no more than 10% of the requests are namespace operations (e.g. GETADDR, SETADDR). There will be 10,000 active Linux users, connecting over NFS.
Which cluster configuration would you recommend?
A. Ten X200 (27 TB) 48 GB RAM, 600 GB SSD, N+2:1
B. Five X400 (120 TB) 96 GB RAM, 2.4 TB SSD, N+2
C. Ten X400 (60 TB) 48 GB RAM, 2.4 TB SSD, N+2:1
D. Eight X200 (36 TB) 24 GB RAM, no SSD, N+2:1
Your customer's site uses an old X-Series cluster, and they are interested in consolidating their two primary workflows. iostat shows that one of the applications is sensitive to latency, while isi statistics indicates sensitivity to disk response times. There are approximately 1000 users accessing 70 TB of file data.
Which node type would you recommend?
A. S200
B. X400
C. X200
D. NL400
A customer is making a decision between Isilon and a competitor's offering. They currently have 100TB of usable capacity and are forecasting 100% growth per year for the next three years, which will require them to lease additional space in their co-located data center. The CFO finds ROI and TCO to be important decision criteria.
Which statement best emphasizes the value of Isilon for this customer?
A. Isilon's OneFS data protection policies offer substantially lower overhead than competitive RAID based NAS solutions.
B. An IDC study found that Isilon requires 95% less down time hours per year compared to other competitors.
C. The competition cannot offer a scale-out NAS so as capacity is added to the array, performance may degrade.
D. Isilon's OneFS allows administrators to manage much larger amounts of capacity than competitive offerings.
A customer has eight X400 24GB RAM that supports 400 client connections today The customer plans to add 400 more clients in the next few months. They are looking at adding an A-Series node to the cluster to help with client connections.
Before they start adding client connections, what hardware change do you recommend?
A. Add RAM to offset concurrent client connections
B. Add an A100 to offset concurrent client connections
C. Add nodes with SSD to help with connections
D. Add more network switches to increase the number of connections
You get a call from a customer that has just added 200 user connections to the cluster. They want to know how fast they are writing data with these new users.

A. InsightIQ
B. Network Monitor
C. Wireshark
D. Watch4net
