This is part two of the xSP Insider's focus on Storage Service Providers (SSPs). This edition discusses how to conserve bandwidth when outsourcing your primary storage.
Conserving bandwidth for primary storage--An emerging SSP model
The expense of purchasing highly available bandwidth is one of the biggest reasons companies have been slow to adopt the Storage Service Provider (SSP) model for primary storage. Fortunately, today, many SSPs and storage vendors are offering alternatives that give companies the benefits of storage-on-demand, 24x7 monitoring, and world-class storage management without gouging their connectivity pocketbooks.
"Experience has shown that the early SSP models that use disks on a string to provide primary storage just don't work," said Kirby Wadsworth, cofounder and VP Marketing for Storability, a provider of automated storage assurance services. "Plugging remote disks into local servers is a solution fraught with latency, bandwidth, security, as well as control issues. In addition, high-speed fiber simply isn't available to many remote locations."
To address some of these problems, many SSPs have partnered with collocation facilities (IDCs) to provide fiber channel connections for hosted servers. "Delivering storage as a utility service within the collocation facility environment can work well," Wadsworth said. "However, the user has to be comfortable with a shared storage environment with
Newer remote-management SSP models virtually eliminate bandwidth issues by managing storage located at the customer's site. "Using a 56KB line our highly-trained storage professionals can remotely monitor and manage a company's onsite storage 24x7. In addition, we work with storage vendors to install and service step-lease storage subsystems (storage on demand). So, as with an SSP, you only pay for the storage you're actually using as each disk is turned on-but at a much lower cost than leasing gigabytes per month from an SSP." Wadsworth says that for economically addressing offsite storage replication and backup requirements, look at Telcos: "Your Telco often will have the lowest overall cost of delivery, since they have bought and buried infrastructure, including network pipes to your building."
