Exam 11: ScaleIO 1.x Server-Based SAN

You are designing a ScaleIO solution for a workload of 12,000 IO/sec with a profile of 60% reads, 40% writes. What is the total I/O rate that can be expected in ScaleIO devices due to this workload?

What is the mandatory input in the CSV file of the ScaleIO Installation Manager?

You are attempting to add multiple devices to a single storage pool. Which restriction is enforced by the ScaleIO CLI?

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?

Using the ScaleIO GUI, how are devices added to an SDS?

In a ScaleIO environment, how is the Lightweight Installation Agent (LIA) configured by default?

What is the purpose of ScaleIO throttling?

What needs to be reconfigured to enable SNMP traps in a ScaleIO cluster?

Which action can be performed using the ScaleIO GUI?

A ScaleIO cluster has been implemented with one protection domain, one storage pool, and devices from 44 SDS nodes. Each SDS contributes one, 1 TB disk device to the storage pool. Sparing has been configured whereby up to four SDS nodes can fail without data loss. What is the total usable capacity that can be provisioned using ScaleIO volumes?

When creating a volume on a ScaleIO 1.31 ESXi cluster, what are the defaults?

Which action can be performed using the ScaleIO GUI?

What is the mandatory input in the CSV file for the ScaleIO Installation Manager?

In which hosts is the ScaleIO CLI binary available immediately after cluster installation?

When implementing ScaleIO using SVMs in VMware, how is iSCSI used?

You have been asked to install a 200-node ScaleIO 1.31 cluster with a mixture of Linux and Microsoft Windows servers. Which tool should be used?

You want to create a script that performs a sequence of operations in a ScaleIO VMware cluster. What is a valid scripting strategy?

What accurately describes the ScaleIO RAM Cache?

What is optional in the CSV file of the ScaleIO Installation Manager?

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