A customer has grown 2 PB in the last year. The cluster performs well most times of the day, but occasionally during the day, the customer notices a decrease in performance. You have been told that `tree-deletes' are taking too long and can only be run on weekends.
What would you recommend to speed up the `tree-deletes'?
A. Add an SSD node tier for metadata to account for at least 2% of RAW capacity
B. Use an A100 node for added CPU performance to help with `tree-deletes.'
C. Add 20% more nodes to the cluster to help with degraded performance.
D. Add an SSD tier for metadata, ensuring all nodes have SSDs.
A potential customer uses a solution from an EMC competitor for NFS storage in their main data center. The existing arrays are five years old, and the customer would like to consolidate them into a single new system. The entire workload is generated by eight Linux hosts connected to the arrays that process video files. The customer informs you they are not able to collect performance information from the existing arrays.
Which tools can capture the workload requirements?
A. iostat and nfsstat
B. MiTrends and netmon
C. netstat and esxtop
D. Wireshark and sysstat
A potential customer has 540TB Raw capacity of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. Their authentication sources are LDAP and Active Directory. Their users are primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days. They do not know the average file size or the number of aggregates they are managing.
Which tool(s) would you use next to complete your sizing?
A. MiTrend WPA, Autosupport, and PerfCollect
B. Isilon Cluster Sizing Tool
C. Wireshark, isi statistics, and iostat
D. Isilon Insight IQ, OnCommand Insight, and nfsstat
A potential customer has about 540TB of NetApp running in ONTAP 7-Mode. They are willing to let you gather some workload data. They have LDAP and Active Directory authentication and primarily Windows Clients. They are very interested in Automated Tiering and Large Scale Archives. They are not certain about the workflows from the Marketing Department. The Content Team will only say they need to acquire 300 TB within 90 days.

Which tools would you use to gather information to do your Isilon sizing?
A. MiTrend WPA, Autosupport, and PerfCollect
B. isi status, isi_netlogger, and PerfMon
C. Wireshark, isi statistics, and iostat
D. Isilon Insight IQ, OnCommand Insight, and nfsstat
Your customer has an existing Isilon cluster comprised of five NL-Series nodes. They have a new project that will quadruple their current throughput requirements. Upon reviewing reports in InsightIQ, you see that the aggregate external network throughput is peaking at 600MB/s. The customer states that data is only active for the first 7 days, but they keep it indefinitely.
Which recommendation best supports their growth requirements?
A. Add X-Series nodes to the cluster, and use SmartPools to migrate inactive data to the NL-Series nodes.
B. Use the Isilon Sizing Tool to determine GNA requirements, and add NL-Series nodes with SSD to the cluster.
C. Add a VNX Unified array for the new project, and use rsync to migrate data to the Isilon cluster for archiving.
D. Add A-Series nodes to the cluster to boost combined network performance.
You have been working with a customer to size a new Isilon cluster for their environment. You recently determined that a cluster with three X400 nodes with 1TB drives and 48 GB RAM would be a perfect starting point for their workflow, but will have extra capacity. The customer just informed you that they have decided to also use the cluster for a small home directory environment and implement SmartQuotas.
Which configuration changes should you consider?
A. Increase the memory and add SSDs to the configuration.
B. Add an additional X400-Series node to the configuration.
C. Add three NL-Series nodes with 1 TB drives with 48GB RAM, and use SmartPools.
D. Add three S-Series nodes with 300GB drives with 48GB RAM, and use SmartPools.
You are designing a new Isilon system to store mobile device video clips. The files average 800MB in size and the application team tells you to plan for up to 15,000 new files per day. The product manager for this new service wants enough capacity for the first year and reminds you that response time for storing and retrieving the files is important for customer satisfaction.
The files will be accessed frequently for the first 48 hours after creation, and then very infrequently after seven days. You plan to use N+2:1 protection, and will configure a SmartPools policy to move inactive files to an archive tier within the cluster.
Which configuration best fits the project requirements?
A. 4 x X200 nodes with SSD; 36 x NL400 nodes with 4TB drives
B. 38 x X400 nodes with 4TB drives and SSD
C. 4 x S200 nodes with SSD; 45 x NL400 nodes with 3TB drives
D. 4 x X400 nodes with 1TB drives; 36 x NL400 nodes with 4TB drives
A customer is inquiring about expanding their primary cluster consisting of six S-Series nodes in order to improve performance. They have a second cluster with 11 X-Series nodes. Both clusters leverage 1GbE, but the customer recently installed a 10GbE network that can be utilized. They also have multiple Fibre Channel SAN arrays in their environment.
They have a variety of workloads on each cluster and are in the process of determining which workloads belong on which cluster. They have discovered that one of the workloads- a SQL database that resides on the X-Series node cluster - is experiencing timeouts due to latency. The database vendor has suggested limiting latency to 5ms or less to eliminate these timeouts.
How do you advise the customer?
A. Consider migrating data from Isilon to one of their SAN platforms or proposing a new solution to handle the performance requirements of SQL.
B. Merge the S-Series nodes and X-Series nodes into one cluster, upgrade the 1GbE to 10GbE, and leverage SmartPools to allow for the cluster to determine where data should reside.
C. Suggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to boost the performance of each cluster.
D. Recommend they increase the amount of DRAM in the cluster or consider an Accelerator node in order to increase the amount of cache in their cluster.
You are sizing an Isilon cluster for a new customer. Analyzing their workflow you determine that they have a large block random read workload.
What is the most important factor to consider when sizing this solution?
A. Bandwidth
B. IOPS
C. Latency
D. Headroom
A cost-conscious customer is exploring Isilon for their PACS archive. The workflow consists of one hundred cases a day, each including fifty 60MB image files. However, each image will have five-hundred 64kB metadata files associated with it. They currently have six years worth of archived data. They will need to migrate to the new solution and they need to plan for an additional three years of archive capacity.
Which solution would you recommend to fit their capacity needs?
A. 24 NL-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
B. 18 NL-Series nodes with N+2:1 protection policy providing 2078 TiB of useable capacity
C. 24 X-Series nodes with N+3 protection policy providing 2597 TiB of useable capacity
D. 12 NL-Series nodes with N+2 protection policy providing 1300 TiB of useable capacity
