Enterprise Storage ServicesMission, Vision & Plan

Mission

To provide excellent and reliable data storage and backup services to UCIT and it’s customers in a cost-efficient manner.

Vision

• Deliver Enterprise Class Storage and Backup Services

• Reduce Dependence on Tape Backup• Develop Full Disaster Recovery capability• Fully Embrace “Yes We Can!” for all

services

Where are we????

Applications

• Blackboard• UC Flex• Virtual Hosting – Server and Workstation• File Sharing• Database

Storage History

Current Storage Issues• Backup Tasks and Database Load Tasks utilizing

NS480 are expanding into first shift potentially affecting user access.

• Storage Processors on NS480 approaching maximum utilization due to high SATA drive usage

• Critically low on space – unable to meet demands of new customers and applications.

• Even though shelf space in NS480 is available, unacceptably high storage processor utilization prevents all but minimal expansion using the more expensive fiber channel drives.

• Unable to complete migration off of aging CX-700 due to unavailability of space.

• Unable to complete migration off of aging Tagmastore due to unavailability of space.

Backup History – Nightly Avg.

Tape Utilization

Current Backup Issues• Constantly running out of tapes to keep offsite pool

up-to-date. Running out of tapes causes backups to fail.

• We have never retired a tape. 9940 drives are hard on the tape leaders and once broken, the tape cannot be read.

• Current VTL is rapidly running out of space. IBM recommends against and does not support expansion.

• Full maintenance contract for SL8500 not cost effective. Currently only library and software on maintenance. We are self-insuring drives.

• Oracle support for Storage Tek product line is unacceptable for enterprise class organization.

• Limited capacity of current tape drives causes backup sets to be spread across too many tapes. A full restore requires all tapes be read perfectly. A full restore of aitl-fs03 would require 180 tapes. The probability of reading 180 old tapes without error is low.

Where are we going??

Symmetrix Configuration

• (2) VMAX Engines• (16) 8GB Front End Fiber Channel Ports• (8) 8GB Multi-Mode Ficon Ports• 128GB Cache• 163TB Usable Capacity with EFD, Fiber

Channel and SATA• FAST-2 Dynamic Tiering

Tape Deduplication

• Process of removing duplicate information during the backup process, thus requiring less storage space and less replication transmission time.

• Deduplication rates vary but based on our application mix, a 6:1 deduplication ratio is not unreasonable to expect.
