SSD is often talked about as a performance solution for online transaction processing, high performance computing, and applications where cost per IOP is sometimes more important than cost per GB. However, SSD is about much more than that. There are times when there’s simply no other reasonable way to solve an I/O performance problem. There are two case studies on the Kaminario site you should check out if you want to know the breadth of what SSD can accomplish, particularly when you have the freedom of choice theK2 provides.
The first case study is about the Israel Electric Company (IEC), which provides electricity for more than 2.5 million Israelis in all sectors of the economy. The IEC has been replacing a hodge podge of different IT systems with a single SAP ERP solution. Shortly after the first round of ERP modules went live, users started complaining of performance issues with lots of transactions, queries, and reports, despite IEC’s use of some of the most powerful servers, disk storage systems, and databases on the market. A thorough analysis revealed I/O performance as main culprit, which brought the IEC to Kaminario and a K2 filled with DRAM. The result was an improvement in transaction speed by up to 25 times–10 times on average–and latency by up to 7 times, even during resource intensive operations that would formerly slow things down to a crawl. Imagine the productivity improvements.
