The economics of disk storage have changed forever.
With fully redundant enterprise storage available for under $125 per TB including thee years of maintenance coverage, it's time to toss out your old, end-of-life RAID storage systems.
Here's an example of the new economics of storage:
EMC RAID array, 108TB raw capacity with 54ea 2TB drives. 4Gb Fibre channel, total 13U enclosures. Cost of out-of-warranty maintenance $17,000 per year (estimated). This system will cost you $51,000 (estimated) to maintain it for the next three years.
Nexsan E18P RAID array, 216TB raw capacity with 18ea 12TB drives. 8/16Gb Fibre channel, 2U enclosure. Costs $50,000 (estimate). Includes three years of maintenance (warranty) coverage.
Your action item: Replace or repurpose old storage array with Nexsan E18P. Purchase price is less than 3 years coverage on your old system, doubles your capacity, and includes 3 years of maintenance with the price while improving uptime due to fewer moving parts.
