Hi, we're working on 2 new datacenters to provide datavault/DR services to clients in three service tiers: cold, worm and hot. This will also be a traditional service provider DC with internet and hosting services. DC1 will be 2-3K Sqm. DC2 will be very small running as backup. there is a plan for 2 more DCs similar to DC1. initial equip providers include core networking from HP Procurve, WAN from Juniper/cisco, Power/cooling from emerson-liebert/APC, secutiy/fire from tyco/others. Computer room initial design based on blades and iSCSI SAN from Intel for core/client services. will also include HP/intel/IBM servers for unix/linux and sun for other client requirements on need basis as well as AS400. We intended Intel Blades with Intel MJ2 GRID iSCSI SAN. Please note we will try to virtualize as much as possible w/o complexity. Not sure if this SAN/initial architecture will do the job, a) need to consider interconnection including fiber, b) supporting all user environments as mentioned c) scalability (expect 200TB in first 2-3 years d) online and offline geo sync/async replication, e)tape storage as well. f)strong single NOC Management but roles reversible between data centers. I know there is know easy way to say this, but if you can give sort of a shopping list of software/hardware needed and proposed budget. datacenter is on 6500sqft with 50% for computer room. we need to be cost effective, integrated and well managed to the second. we aim for five 9s. thanks in advance.

Thanks. We'll let you know when a new response is added.

Instead of buying all that hardware just virtualize it and save yourself thousands of dollars in labor and maintenance costs. That’s what I do.
