To achieve both capacity and performance in classic SMB storage, many hard drive spindles are needed to build up sufficient IOPS (Input Output Per Second). Drobo B1200i achieves both capacity and performance in the same system with a small number of SSDs and automated data-aware tiering technology, technology that is not available with other SMB storage.
Configuration comparisons may display higher capacities in the calculator in order to also meet the required IOPS for the selected range and best match comparable performance, particularly when using 2TB 7200RPM drives.
A recent survey conducted by TechValidate confirms Drobo cost savings are real. Customers reported an average of $12,315 savings by using Drobo vs. traditional SAN alternatives. See details of the survey @ www.techvalidate.com/product-research/drobo-san-storage-for-business.
Notes on Numbers
- Prices are list price (MSRP) before discounts as of July 30, 2012 @ www.dell.com/us/business/p/ and www.cdw.com; prices subject to change.
- Prices are for base hardware and software only; savings are larger when you take into account reduced rack space, power, cooling, and management associated with using fewer systems to deliver targeted capacity and performance.
- IOPS metrics are based on accepted values: 75 IOPS for 7200 RPM 2TB drives, 150 for 15K RPM 600GB SAS drives, see www.aarondelp.com/2009/10/its-now-all-about-iops.html.
- Compared IOPS account for hot spares and parity drives for common RAID group configurations configured for striping with parity.
- Compared configurations based on the addition expansion chassis where applicable (e.g. Dell MD3200i with MD1200i, HP P2000 G3 with D2600 enclosure).
