When it comes to storage performance testing, I remind people of the “Three R’s” —relevance, repeatability and results. Relevance Matters Relevance is all about testing in such a way that your testing results will somehow correlate with observations in production. After all, it’s why you...
Network Performance– As Virtual SAN is a scale-out storage solution, performance of the network interconnects is also a key factor in validating performance. If you observe high latency during a test run, the next step is the isolate the source of the latency. An easy way to figure out wh...
Performance issues may be caused by several different areas such as CPU constraints, memory overcommitment, storage latency, or network latency. If one or more of your virtual machines has a bad response time, consider each of these areas to find the bottleneck. Resolution Each step below provide...
Azure Blob Storage is an example of an object storage model. While object storage works well for many modern development solutions, most workloads running in virtual machines will use block storage.The configuration of your managed disks is important to the pe...
相反地,Oracle 提供名為 DB_BLOCK_SIZE 的參數,您可用來設定資料庫的 I/O 要求大小。如果您使用的應用程式不允許變更 I/O 大小,請根據本文中的指導方針,將應用程式最相關的效能 KPI 最佳化。 例如:OLTP 應用程式會產生數百萬個小型和隨機的 I/O 要求。 若要處理這種 I/O 要求,您必須以提高 IOPS 為重點...
cannot boot on a Red Hat Enterprise Linux 7 host. To work around this problem, use a different storage type, such as IDE. Note, however, that using a different storage type has a negative impact on storage performance. For an alternate workaround, seeWindows Support Case 2795397. (BZ#152...

3.Slower networking for storage, manifests itself inworse storage performance, specifically on large throughput operations, but also short microbursts where latency will creep up. Keep in mind that 10Gbps sounds like a lot but that is *per second*. If you are trying to get a large block of...
