You are working with a local children’s hospital on a full storage refresh proposal. The hospital has implemented a three-tier storage strategy as detailed below.
Tier 1 - Business critical 24×7 databases, email applications, and data warehouses. Also includes any other applications that have high availability and heavy write performance. This data is replicated to a disaster recovery site to ensure no data loss occurs in addition to standard backup practices. Currently 50 TB on HP XP12000.
Tier 2 - General user file shares and non-critical databases. Minimal downtime can be tolerated, and high performance is not required. This data is backed up daily. Currently 150 TB on multiple HP EVAs.
Tier 3 - Long-term archives of user data. The data is moved from Tier 2 to Tier 3 as it ages. Downtime can be tolerated, but data must be maintained. Backups are only done when new data is added to the archive. There are currently 250 TB on multiple HP P2000s.
Costs for ongoing maintenance and management are escalating, and the hospital is looking for ways to reduce costs and re-deploy storage management staff even with the annual 10% growth.
You are designing an HP 3PAR StoreServ solution to meet their needs and are using the HP Storage Sizer to make your calculations.
Which workload mix meets the hospital’s needs for storage for the next year?
