7 D. Data deduplication /Reference: In the output of the Comprestimator, the Total Savings is presented as a break-down of thin-provisioning savings and compression savings. This helps in future planning tasks; when the volume stores more data than it does today, thin-provisioning savings get lower, but compression savings are expected to stay the same if new data written to the volume is of the same nature as the data stored in the volume today. References: QUESTION 10 A customer is implementing an IBM Storwize V7000 Unified solution and will access both file and block storage. Two fibre channel adapters are included within each controller. What is the maximum number of fibre channel connections the customer can connect to its SAN fabrics? A. 12 B. 6 C. 4 D. 16 Correct Answer: D /Reference: With the introduction of the nodes, and the ability to have up to eight FC ports per node, there are several different options that are valid for attaching storage to the Storwize V7000 Gen2 cluster. Apply these Storwize V7000 Unified configuration details for Fibre Channel and Fibre Channel Over Ethernet (FC/FCoE Gateway, FCF) switches to ensure that you have a valid configuration. Configuring your SAN with at least two independent switches, or networks of switches, ensures a redundant fabric with no single point of failure. If one of the two SAN fabrics fails, the configuration is in a degraded mode, but is still valid. You should maintain separate fabrics for FCoE and FC. If you attempt to combine these fabrics, you might risk adding additional paths to the volumes. Supported configurations allow a maximum of eight paths.

References: IBM Spectrum Family, IBM Spectrum Control Standard Edition, page QUESTION 18 A customer is concerned that its volumes would not have access to the full system cache but wants to create pools to limit the amount of space that different departments use. Which activity allows the customer to meet these requirements? A. Create several small pools that correspond to LUN size policies B. Create a single storage pool that contains all the MDisks C. Create LUN size policy in the GUI and set system cache to global via the CLI D. Create a single parent pool that contains smaller child pools Correct Answer: D /Reference: Before V7.4, the disk space of a storage pool was provided from MDisks, so the capacity of a storage pool depended on the MDisks capacity. Creating or splitting a storage pool is not possible and a user cannot freely make a storage pool with a particular capacity they want. A child pool is a new logical object that is created from a physical storage pool and provides most of the functions that Pools have (for example, volume creation), but the user can specify the capacity of the child pool at creation. A child pool is an object similar to a storage pool, and can be used interchangeably with a storage pool. It supports volume copy and migration.
