IBM DS4800 as a Disaster Recovery Platform

By Molly Webster


A disruption of your company processes could leave your entire organization exposed; this could create a very immobilizing predicament. Today's companies face escalating customer demands and expectations-there is no room for downtime.To be able to prevent unforseen outages from disrupting your organization, it is a wise decision to plan ahead by having a disaster recovery platform on hand to deal with such situations.

The objective of thorough disaster protection planning is to protect the applications that run your company and reduce unplanned downtime. However, one essential consideration is that all preparing for any sort of a disaster-tolerant remedy is often subject to balancing the answer versus the downtime versus the price.

The DS4800 Disk Storage Method is created to provide effective, dynamic capabilities that help shield data and prevent failure, not just respond and recover. In the event of a true disk recovery event, Point-in-time copying with IBM FlashCopy, copying a volume with VolumeCopy, and remote mirroring with Enhanced Remote Mirroring can supply enterprise-class disaster recovery techniques.

A lot more importantly, the reasonable price of a DS4800 as a disaster recovery platform makes it a feasible platform for implementing disk recovery for your business.

A 4U rack-mountable enclosure houses the DS4800 redundant, dual-active intelligent RAID controllers equipped with 8 x 4 Gbps ports (four ports per controller) for attachment of host servers and DS4000 Storage Expansion Unit enclosures.

The DS4800 attaches up to fourteen EXP810 DS4000 Storage Expansion Units, supporting configurations up to over 134TB of FC or 448TB SATA disks or perhaps a mix of both types of disk drives by use of the optional DS4800 Fibre Channel/ SATA Enclosure Intermix feature. This helps ensure that different tiers of data are properly tiered in the event of an actual disaster recovery or failover event.
