The Challenge

Hosteur is a leader in the French web-hosting market with responsibility for tracking millions of emails for over 40,000 websites. Hosteur customers range from small companies with simple systems to name-brand customers such as Nestlé, Generali, and Insurance Carrefour.

Hosteur’s SQL Server-based email system provides analytics that help customers manage their online businesses. For example, retail companies can monitor the sending and opening of invoice confirmation emails. Similarly, eCommerce companies can monitor the effectiveness of promotional emails by tracking when users open or click promotional links.

Laurent Escart, CEO of Hosteur, described the challenge this system faced: “We send eight to 10 million email a day, tracking different information for each email. Storing and accessing all this data quickly requires a very high performance system.”

Hosteur needed to:

  1. Increase the performance of the email tracking system
  2. Keep a minimal server footprint
  3. Provide headroom for future growth
  4. Support a virtual environment
  5. Be easily managed and supported by Dell

The Solution

Mr. Escart and his team solved all of these problems by moving active data off local hard drives and onto a Fusion ioMemoryTM ioDrive® product.

Quadruple the Performance
Mr. Escart said his previous hard disk-based system could only process about half of their eight million emails per day.

The Fusion ioMemory solution completely eliminated this problem. “We estimate we can send three to four times the volume of email per day than we used to,” Mr. Escart said. “We now regularly process 7 million transactions per day without any slowdown in performance.”

Transactions per Day

With SanDisk
7 million emails
Without SanDisk
1-2 million emails
“We estimate we can send three to four times the volume of email per day than we used to.”

Laurent Escart, CEO, Hosteur

Mr. Escart noted how this performance improves Hosteur’s customer service: “We estimate the overall server workload capability to be about 10X of the prior system. This increases the value of the services we provide to our customers, as we can now process all email transactions, and are even expanding the types of events we track. Individual email response times are also faster, which improves our customers’ responsiveness to their end customers.”

Scalability Made Simple
As a leader in the hosting space, Hosteur’s innovative IT team wanted to design a solution that would do more than just meet its existing performance challenges—it also had to scale easily to support future growth.

Fusion ioMemory was an ideal fit. “We estimate we can scale server workload to 16 million emails per day simply by adding more Fusion ioMemory capacity to the same server,” Mr. Escart said. “This makes it easy to support future growth.”

Virtualizing a Data-Intensive Database
Fusion ioMemory’s VMware-ready status facilitated a secondary goal of Hosteur’s— to virtualize even data-intensive databases, making them easier to manage.

Mr. Escart said, “Virtualization was not practical with the previous disk-based system because of performance limitations. We tested Microsoft SQL Server in the VMware Hypervisor on ioDrives, and it worked perfectly. We are now running the virtualized database in production.”

Full Dell Support
Mr. Escart noted the value of SanDisk as a qualified and supported solution by Dell. “We have a valued partnership with Dell. Their solution experts helped us obtain the Fusion ioMemory products, design the solution around our needs, and implement it.”
