Correct Answer: A

Three core software components are needed for a successful implementation of VVols. The minimum code level required for each component is provided in the following list:

*

IBM Spectrum Control Base Edition (SCB) version 2.2.1 (or higher)

*

Compatible storage system running IBM Spectrum Virtualize version 7.6.0 (or higher

*

VMware vSphere 6.0 (or higher):

?VMware ESXi version 6.0

?VMware vCenter Server 6.0 or vCenter Server Appliance (vCSA) 6.0 (vSphere Web Client 6.0)

)

We use the term VVols-enabled host to describe a host that meets the following requirements:

*

VMware ESXi (ESXi) version 6.0 or later installed.

*

Registered with the storage system with host type set to VVol. Note that in the CLI, the VVol host type is referred to as adminlun. References: Configuring VMware Virtual Volumes for Systems Powered by IBM Spectrum Virtualize , page 6, page 11 http://www.redbooks.ibm.com/redbooks/pdfs/sg248328.pdf

Correct Answer: A

Spectrum Control provides analytics-driven storage management and efficient infrastructure management for virtualized, cloud, and software-defined storage to simplify and automate storage provisioning, capacity management, availability monitoring, and reporting.

IBM Spectrum Control communicates with Storwize V7000 storage systems through a native interface.

Use IBM Spectrum Control to monitor Storwize V7000 systems, including discovery, data collection (probes), performance monitoring, trending, storage optimization, and provisioning. IBM Spectrum Control reports and topology views also provide information about the tier, tier capacity, and tier free capacity for Storwize V7000.

Correct Answer: C

v6.2 Storwize V7000 offers both Scale-Up and Scale-Out possibilities for ultimate flexibility.

Control enclosures support attachment of up to nine expansion enclosureswith configurations up to 360 TB physical internal storage capacities (for Storwize V7000, up to 1.44 PB in clustered systems) Flex System V7000 can scale up to 240 (2.5" disks) per control enclosure; 960 (2.5" disks) per clustered

system. References:https://en.wikipedia.org/wiki/IBM_Storwize_family#Storwize_V7000
