Purchase EMC : E20-554 Exam Materials and then pass exam easily

A customer has eight X400 24GB RAM nodes that support 400 client connections. They will be adding 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 more network switches to increase the number of connections
• B. Add an A100 node to offset concurrent client connections
• C. Add RAM to the nodes to offset concurrent client connections
• D. Add nodes with SSD to help with connections

Which Isilon feature provides the ability to build a cluster using different node types and tiers to meet a customer's business objectives?

• A. SnapshotIQ
• B. SmartConnect
• C. SmartPools
• D. SmartQuota

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. 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.
• B. Consider migrating data from Isilon to one of their SAN platforms or proposing a new solution to handle the performance requirements of SQL.
• C. Suggest the customer consider leveraging SSDs in the new nodes they purchase and GNA to boost the performance of each cluster.
• D. 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.

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.

-- Exhibit -
A European Sports TV network is considering Isilon for their Media Edit Storage for their editing workloads. They are also considering Isilon for near-line media archiving.
The network receives XDCAM HD footage which is loaded onto their existing Transcoding Storage platform. New footage that needs to be edited will be transferred from their Transcoding Storage platform to the proposed Media Edit Storage platform at the rate of ten simultaneous XDCAM HD files via FTP. Edited files will be transferred back to the Transcoding Storage platform at the rate of ten simultaneous XDCAM HD files via FTP.
The network currently has 15 Final Cut Pro edit stations, 15 Avid edit stations. Proxy software will be used to allow Isilon to act as the storage for the Final Cut Pro and Avid media. Three of those edit stations will be performing content compositing as needed.
The network expects 70 hours of new content per week, and 50 hours of edited content per week.
They intend to keep the new and edited content on the proposed Media Edit Storage as a performance tier for 30 days. They would like to retain all new and edited footage proposed Media Edit Storage as a near-line tier for two years.
In addition to the current workloads, the network expects to implement a new Media Asset Management (MAM) solution and has requested the Isilon cluster be capable of supporting 120 MBps read and 120 MBps write to support the MAM requirements.

Refer to the exhibit.

Based on the described use of the cluster, what are the customer's capacity requirements?

• A. 30 days retention: 30 TB; 2 years retention: 720 TB
• B. 30 days retention: 15 TB; 2 years retention: 360 TB
• C. 30 days retention: 1 TB; 2 years retention: 24 TB
• D. 30 days retention: 5 TB; 2 years retention: 120 TB
