Answer : D

A ScaleIO cluster has been configured with 10 nodes running only SDS, 20 nodes running only SDC, and one storage pool with all devices. Each SDS contributes four HDD devices to the storage pool. Each server has one 10 Gb network interface. The I/O workload is random access with a 4 Kbyte block size.
What is a limiting factor for IOPs?

  • A. Number of HDD devices
  • B. Number of SDS nodes
  • C. Number of SDC nodes
  • D. Available network bandwidth


Answer : A

  • B. Unmap a volume from an SDC
  • C. Disable restricted remote access
  • D. Upgrade ScaleIO to a newer version


Answer : A

An application is using two ScaleIO volumes that have been provisioned to a host. You want to use the ScaleIO consistency group feature to snapshot both volumes.
What is a restriction?

  • A. Both volumes must come from the same ScaleIO cluster
  • B. Both volumes must come from the same protection domain
  • C. SDC must be disconnected from the host first
  • D. Host operating system must be Linux


Answer : A

How many simultaneous instances of the ScaleIO GUI can be running for a single cluster?

  • A. One per ScaleIO cluster
  • B. Dependent on the client OS
  • C. One instance per role, per ScaleIO cluster
  • D. Dependent on the role of the specific user


Answer : A

You are performing sizing calculations for a ScaleIO cluster with all servers having the same hardware configuration. This effort is being performed for a prototyping lab and high availability is not a concern. You have estimated that aggregate I/O traffic to all ScaleIO devices is 140 MB/sec.
What is the minimum network configuration that can support this workload?

  • A. One 1 Gb NIC per server
  • B. One 10 Gb NIC per server
  • C. Two 10 Gb NICs per server
  • D. Four 10 Gb NICs per server


Answer : B
