Austin Independent School District Graduates to a greener datacentre with 3PAR Utility Storage
February 2010 by Marc Jacob
3PAR announced that the Austin Independent School District (AISD) has deployed the 3PAR InServ® T400 Storage Server as part of a green datacentre initiative. AISD chose to invest in highly virtualised storage servers from 3PAR as a more agile and efficient, green alternative to their aging Storage Area Network (SAN) of legacy storage arrays. Since deploying the T-Class array, AISD has saved 55% in storage costs. The school district has also been able to keep power demand increase down to less than 30%, even after doubling the size of its datacentre, by leveraging 3PAR Thin Provisioning. With 3PAR Utility Storage, AISD has the ability to non-disruptively reconfigure storage online and was able to avoid hiring a full-time storage administrator—an expense that would have been necessary with traditional storage.
AISD chose 3PAR Utility Storage due to the highly virtualised storage platform’s established reputation for leading-edge thin provisioning capabilities as well as its administrative simplicity—as demonstrated over a series of trials in which AISD pit the InServ T400 against traditional systems from legacy storage vendors. With AISD’s previous storage environment, management was such a challenge that it had been years since the school district had made any changes to their SAN. The InServ T400 not only brought autonomic storage capabilities to AISD, but also mixed-workload support and the ability to combine both Nearline and Fibre Channel drives within the same system for cost savings, increased flexibility, and simplified management.
A key element of the industry’s most mature and robust thin provisioning offering, 3PAR Thin Provisioning software was also a crucial decision factor for AISD. Historically, users and applications were only actually using a fraction of their allocated space to hold written data. The rest of the space was being allocated up-front but left unused—an enormous waste of capacity, power, and space. As a result of deploying their InServ T-Class array with 3PAR Thin Provisioning, AISD no longer struggles with low utilisation rates and is no longer forced to negotiate the amount of space it can afford to allocate to each of its more than 90,000 users. Instead, AISD is able to allocate any amount of virtual storage up-front while physical capacity is only consumed as user applications require that space for actual written data. As an application writes new data, free capacity within the array is configured and provisioned autonomically—intelligently, automatically, and without consuming administrative resources. Many competing thin provisioning implementations require manual configuration and pre-dedication of capacity to pools, increasing administration time and reducing achievable capacity savings. The efficiency of 3PAR Thin Provisioning has increased capacity utilisation, eliminated waste associated with allocated-but-unused capacity, and streamlined the storage management processes at AISD.
Prior to “greening” their datacentre, power and cooling were major issues for AISD. In addition to 3PAR Thin Provisioning, AISD chose economical, power-efficient, and high-density Nearline SATA drives instead of premium Fibre Channel drives in their 3PAR array to reduce floor space, power, and cost. Nearline SATA drives are effective for a variety of workloads when used in combination with the InServ’s wide striping, which effectively spreads each application data volume over every SATA or Fibre Channel drive in the array to simultaneously deliver high performance and high utilisation levels. Nearline SATA drives deliver higher density for the same power consumption, thereby extending the life of the school district’s energy-strapped datacentre.
