In a previous post, I talked about the evolution of the Flash memory market, and how some software solutions are starting to change the way we consume storage. Whenever a new hardware technology comes into market, the previous ones becomes of general use (think SSDs), but the software has always the advantage to leverage any improvement in the underlying hardware, and often re-invent itself. Lately, the common idea in at least two solutions I’ve seen, is the new storage tier they are offering use to use: your servers’ memory.
Whenever there is a new idea, a new movement, a new music style, any new thing in any aspect of life, we can observe more or less the same timelines during its lifecylce. These days, I’m starting to see the same traits in the Flash PCIe market.
At the beginning there is the explosion of a new market. Someone launches a new technology (or it can be a new music genre, this example works in different areas), and suddenly a completely new market has born. They had an idea, they identified a new need from customers, or the same need that could have been solved in a different and better way. In this case, the bottleneck created by old bus connectors like SATA and SAS were preventing the complete use of insanely fast Flash memories. By connecting the same memories directly into the PCIe bus, that bottleneck was removed and customer could experience better performances.
PernixData is, as of today, the only server-side caching solution for VMware offering write-back capabilities, that is the possibility to accelerate write operations. This feature is extremely helpful in increasing performances in virtualized environments running write intensive applications like databases, mail servers and others. However, the usage of this feature requires some proper configuration in order to correctly protect VM with Veeam Backup
Few weeks ago I published an article titled “My new “I/O Test Virtual Machine”, telling you about the VM I built to run my performance tests for virtualized environments. After a first post running those tests against my “plain” Lab and its enhanced version using another server-side caching solution, many of you asked me if I was planning to do the same tests with PernixData. So i did, and here are my findings.
Quando progettate una nuova installazione di PernixData, è possibile utilizzare un cluster in cui non tutti i server ESXi sono dotati di memoria Flash (sia essa su scheda PCIe o su SSD); tuttavia, è vi sono alcune accortezze da rispettare, sia in fase di installazione che di utilizzo.
If you are designing a new project with PernixData, you can have a cluster where not all ESXi servers have a Flash memory (a PCIe card or an SSD); however, there are some design considerations you need to keep in mind, both during the installation part or while using this software.
Since its first public appearance at the Storage Field Day 3 event I attended on last April, where CTO Satyam Vaghani told us about his company, their technology, and demoed us their produtct, there has been a huge hype around this young startup. PernixData has only one product, called FVP (Flash Virtualization…
Fin dalla sua prima uscita pubblica in occasione dell’evento Storage Field Day 3 a cui ho partecipato lo scorso aprile, in cui il CTO Satyam Vaghani ha illustrato la nascita della società, la loro tecnologia e ha dimostrato brevemente il prodotto, si è fatto un gran parlare di questa giovane…
