Which recommendations are made when leveraging virtual provisioning?
Your customer is implementing a Unified VNX system leveraging CIFS general purpose file shares. They are implementing all virtual provisioning and FAST features to maximize storage efficiency.
Which recommendations are made when leveraging virtual provisioning?
Which configuration will provide the most efficient use of capacity while still following best practices?
Your customer has just purchased ten 1TB NL-SAS drives for their VNX array. This additional capacity will be used to archive their large image repository.
Which configuration will provide the most efficient use of capacity while still following best practices?
Which configuration best supports their availability requirements?
Your customer has just purchased a new VNX, which will be dedicated to their large SQL 2008 cluster. High-performance and high-availability are critical.
To meet their availability requirements, the customer has requested the configuration be optimized to allow both storage processors to process I/O for any given LUN without trespassing the LUN.
Which configuration best supports their availability requirements?
How would you bring the customer into compliance with EMC best practices with minimal impact?
Your customer’s IT group configured a VNX array and created multiple RAID 5 (2+1) RAID Groups. They just realized their mistake and bought new drives.
How would you bring the customer into compliance with EMC best practices with minimal impact?
Which protocol should be used to connect the servers to the storage array?
Your customer has two clustered SQL servers that require direct access to LUNs located on their VNX storage array.
Both servers are located in the customer’s main office. The VNX storage array is located in the customer’s data center, which is approximately 1.5 km from their office. Both facilities are interconnected using their existing IP network.
Which protocol should be used to connect the servers to the storage array?
Which configurations can be added to this pool?
Your customer needs to add additional capacity to their existing FAST VP which currently contains four Flash drives in a RAID 5 configuration.
Which configurations can be added to this pool?
How will that data be distributed (numbers are approximate)?
Click on the calculator icon in the upper left-hand corner. A customer has a heterogeneous pool with the following configuration:
– 1000 GiB of Flash, with 400 GiB free
– 10,000 GiB of SAS, with 2,000 GiB free
– 80,000 GiB of NL-SAS, with 20,000 GiB free
The customer creates a new LUN with data placement policy set to “auto-tiering”. The LUN is then populated it with 500 GiB of data. How will that data be distributed (numbers are approximate)?
How is that data distributed (numbers are approximate)?
Click on the calculator icon in the upper left-hand corner. A customer has a heterogeneous pool with the following configuration:
– 800 GiB of Flash, with 300 GiB free
– 12,000 GiB of SAS, with 2,000 GiB free
– 50,000 GiB of NL-SAS, with 25,000 GiB free
The customer creates a new LUN with data placement policy set to “highest available tier”. The LUN is then populated with 600 GiB of data. How is that data distributed (numbers are approximate)?
What is your recommendation?
Your customer has recently purchased nine VNX arrays. They would like to utilize their current single Tier 2 backup server to back up the Tier 2 LUNs on all nine arrays, and would like to remain aligned with EMC best practices.
What is your recommendation?
What is the minimum size of FAST Cache recommended for this environment?
Click on the calculator icon in the upper left-hand corner. A customer has four (4) LUNs of 500 GiB each, six (6) LUNs of 250 GiB each, and five (5) LUNs of 100 GiB each. All the drives presently in their VNX system are SAS and NL-SAS. They wish to implement FAST Cache. Your data collection shows the skew to be 95%. What is the minimum size of FAST Cache recommended for this environment?
