Relocation cycles are regulatory failing to complete in an HDT implementation where the customer is also reporting lower than expected performance.What should be done in this scenario?
When testing an external LUN with default mapping on two paths, performance appears constrained and the utilization of the RAID group in the external storage system never exceeds 35% busy no matter how many test threads are generated. You want to increase the utilization of the external RAID group.Which two actions will accomplish this task? (Choose two.)
A user with a diskless VSP G800 uses ShadowImage from the G800 with a virtualized VSP G200 system. Application performance suffers during the frequent ShadowImage resynchronization operations.What should be done to reduce the impact of the ShadowImage throughput in this scenario?
Which three statements are true regarding the Hitachi external storage architecture? (Choose three.)
You are deploying an external storage system and its connection to a VSP G1000. The VSP G1000 has four external pools. You must ensure balanced utilization of the external storage system parity groups within each pool.What would you do to satisfy this requirement?
A customer has a VSP G800 storage system with an HDT pool with internal SAS drives and a virtualized third-party array using SATA RAID 6. The virtualized array is connected to the VSP G800 using four 8 Gbps FC paths. The customer reports performance problems on an OLTP application deployed on a virtualized server using the HDT pool.What are two reasons for this problem? (Choose two.)
