Jack Rahner, vice president of IT operations from AlphaStaff
EDEN PRAIRIE, Minn., Sept. 22, 2010 - AlphaStaff's reputation for providing excellent service to its clients has been the impetus behind the human resource outsourcing company's dramatic growth. Once employing 6,000 people, the success of AlphaStaff's service model pushed its size to more than 80,000 employees in just five years, making it the fourth-largest HR outsourcing company. The rate of AlphaStaff's data growth - which ranges from employee benefits information to taxable rates to payroll information - was quickly outgrowing the company's HP storage system, which couldn't scale to meet business needs or provide the performance needed to handle critical applications.
AlphaStaff needed an intelligent, self-managing storage solution to handle its growing data requirements. With guidance from Compellent partner CDW, Jack Rahner, vice president of IT operations from AlphaStaff, evaluated solutions from HP, NetApp and Compellent, and turned to the Compellent storage area network (SAN) to replace the company's legacy HP storage.
"We handle lots of information for every one of our clients, and our previous storage system couldn't effectively scale to meet our rapidly growing needs. To make matters worse, the increased workload on the legacy system crippled the performance of our important ERP system," said Rahner. "By using automated tiered storage, snapshots that capture block-level changes and thin replication, we now have a high-performance, agile and reliable storage solution that can grow along with us."
Solid state drives (SSDs) with Compellent automated tiered storage have had a measurable impact on data center operations, which has improved overall business operations. By leveraging the Compellent automated tiered storage feature, AlphaStaff has moved 80 percent of its data to lower tiers of 7.2K 1TB and 2TB SAS drives, saving $50,000 a year in disk drive costs and freeing up the SSDs for the mission-critical ERP system. Rahner reports that the SSDs have improved ERP system performance by more than 80 percent, dropping latency from more than 10ms to about 1ms. Furthermore, since data is migrated automatically between tiers, Rahner has been able to reassign a full-time staff member from managing data to more important projects.
Rahner also uses Compellent's space-efficient data snapshots in conjunction with thin replication for disaster recovery.
AlphaStaff Employs Fluid Data Storage To Keep Its Competitive Edge

Jack Rahner, Vice President of IT Operations
AlphaStaff has become the fourth-largest human resource outsourcing company, its reputation built upon an exceptional level of service. Unlike many agencies, AlphaStaff actually becomes the employer of record for its clients' professional workers, even cutting payroll checks. While that gives AlphaStaff a big competitive edge, it also means storing a huge amount of information ranging from employee benefits data to taxable rates.
As the success of its service model took AlphaStaff from 6,000 to 80,000 employees of record in a five-year period, rapid data growth overwhelmed the entry-level SAN that the IT team had been using. "We went from one terabyte of storage to 60 terabytes in five years," says Jack Rahner, vice president of IT operations at AlphaStaff. "Performance suffered, and the SAN was difficult and expensive to scale."
To make better use of its storage dollars and more effectively accommodate the growth of the business, the Alphastaff IT team explored new storage solutions. The team made its choice after seeing Fluid Data technology from Compellent in action. "We compared Compellent to our old storage solution using the same servers and software, and Compellent was 60 percent faster overall than the previous SAN," says Rahner.
...
"Our clients have rapid access to data and business intelligence that was never possible before," says Rahner.
...
"Previously, it took almost a full-time employee to manage the SAN," says Rahner. "Now there is really nothing to manage because of the automated tiered storage. That employee is now focused on rolling out new projects to help make the company more profitable."
Fluid Data tiered storage also reduces storage growth costs for the AlphaStaff team. Since implementation, the system has moved more than 80 percent of the company's data to less expensive lower-tier drives, enabling the team to purchase fewer of the more costly, high-speed drives. "The system gives us over $50k a year is disk drive savings and the ability to not increase internal head count by utilizing our existing SAN engineer for other IT projects plus more targeted performance," says Rahner.
...
"With billions of dollars in other companies' payroll going through us, the ability to roll back to sixty minutes ago, in a fraction of a second, has completely changed our business model," says Rahner. "Our recovery time objective was 24 hours with tape, but is just ten minutes with Compellent. In fact, we've eliminated tape almost completely-we only use it now for monthly archiving."
Compellent Scalability Positions AlphaStaff for Continued Growth
With the company's client list and workforce still growing, Rahner sees the Compellent SAN as a scalable resource that will serve AlphaStaff well into the future. "The Compellent SAN will never require a forklift upgrade, no matter how many terabytes of storage, controllers, or systems we need," says Rahner.
Recently, AlphaStaff easily added 20 TB of new data gained from acquiring another company. Recently, AlphaStaff added solid state drives to its cluster, necessitated by disk latency of the database system and the extreme IO of the ERP system. After implementation, Rahner saw latency drop from more than 10ms on AlphaStaff's busy days to about 1ms. "We can use any drive types in any combination to easily and quickly expand," says Rahner. "The modular growth capability and technology independence we've gained with Compellent is outstanding. It's really the most intelligent way to grow our storage as our business needs change."
