A midsize company has deployed centralized storage and is currently planning to virtualize their servers. They have considered their application into Tiers, with Tier 1 application requiring the same service and performance levels of the current servers.
They have purchased new, high capacity servers for the virtualized environment and are planning to consolidate several physical servers into a single hypervisor. They are know determining the bandwidth requirements of the application in order to purchase the current number of FCME CNAs for each server.
The results of their analysis for Tier 1 application are as follows:
Average SAN Bandwidth: 3 Gb/s
Average LAN Bandwidth: 2 Gb/s
What is the minimum number of CNAs they would need to install an each server to meet the bandwidth required for the Tier 1 application while providing CAN redundancy and high availability?
A company is planning the backup strategy for their virtual machine environment. They are considering migrating to an image based backup model.
Where image-based backup would be processed in the environment?
A hypervisor running virtual servers fails with an unrecoverable error and at virtual server are restarted on another hypervisor. When the application restarts, some data has been lost.
Which type of consistency does this situation represent?
An organization with 25,000 employees moved to a new building that contains a fully virtualized data center with a virtual desktop infrastructure (VDI) instituted for all employees.
Each morning between 9:00 and 9:30, the help desk receives a large number of calls concerning slow performance and timeout issues. The IT department determines that the storage array's Fibre Channel drives are the bottleneck. IT proposes purchasing solid state disks (SSDs) to store the entire VDI environment. Unfortunately, their proposal is rejected because of the cost of the drives.
Which array feature should be implemented to reduce the quantity of SSDs required to service the high I/O bursts of their VDI environment?
You are planning to deploy a virtualized application in a high-availability configuration with automated VM restart on a hypervisor cluster. Your sizing estimates show that peak workload conditions will saturate the processing power of three hypervisor servers.
To meet the SLA, N+2 redundancy is required on the hypervisor servers, with server utilization not to exceed 75% under any conditions.
What is the minimum number of nodes that you should configure in the hypervisor cluster?
