A customer is concerned with maintaining real-time recovery volumes across several hundred kilometers with minimal impact to host response time. Network infrastructure between the two facilities is subject to periodic bandwidth reductions due to surges in overall network activity. The customer is unwilling to invest in additional network capacity.
Which replication approach should you recommend for this application?
What are two ways to improve initial copy time on a Virtual Storage Platform? (Choose two.)
A customer has TrueCopy with a single cascaded remote ShadowImage solution that they resynchronize every two hours. The customer requires disaster recovery testing to be non-disruptive to production and the replication cycle.
What should be considered while planning a disaster recovery test?
What would meet a "near zero" RTO requirement?
A customer is using ShadowImage (SI) on a Virtual Storage Platform (VSP) for a point-in-time copy. The SI P-Vol resides in a SAS HDP pool and the SI S-Vol resides in a SATA HDP pool. During resychronization, the VSP cache write pending hits 60 percent utilization in CLPRO.
What are two ways to reduce the resynchronization impact on host performance? (Choose two.)
A customer is running two production sites. They are using DWDM links to connect their sites. The customer wants to extend their SAN between both sites.
What are two benefits of extending their SAN? (Choose two.)
A customer informs you it is mission critical that Hitachi Universal Replicator volumes reach PAIR status as quickly as possible once the "paircreate" command is issued.
Which system option mode (SOM) will improve initial copy performance?
A customer has two data centers connected using three 4 Gbps Fibre Channel inter-switch links. The business requires that all written data is guaranteed to be replicated and current at the disaster recovery site.
Which replication technology meets this requirement?
What are two concerns when deploying data collectors for sizing replication? (Choose two.)
A customer has 30 hosts to replicate on a non-HDS storage array.
Which tool is used to collect open systems workload data?
A customer is using ShadowImage (SI) on a Virtual Storage Platform. The customer experiences application data corruption on the SI P-Vol and chooses to issue an SI restore copy.
What is the state of SI pairs?
An RPO of six hours has been defined for a site-wide disaster.
Which two actions should be performed to achieve the selected RPO? (Choose two.)
A customer wants to implement TrueCopy replication between VSP arrays. The arrays are 200 km apart.
Which two statements are true? (Choose two.)
You are designing an asynchronous replication solution for a customer. The customer would like to replicate a database and transaction logs. The customer experienced an unplanned outage.
In this scenario, which statement is true?
A customer is planning to replicate 66 TB of data using Hitachi Universal Replicator.
What are two considerations for sizing the expected solution? (Choose two.)
Which two factors will affect ShadowImage resync time? (Choose two.)
