Caching and tiering have been abused by marketing in enterprise IT, often used interchangeably, or simply when not applicable. Luckily, we’ve got a table, it’s round, and surrounded by storage experts. They’ll explain the technical differences between caching and tiering, how to identify which is being used, and what are the performance implications of each.
In this iteration of Gestalt Server News:
– Caching vs Tiering? The On-Premise IT Roundtable wants to clear up the confusion!
– StorMagic’s SvSAN for the edge
– and weird DNA storage
Plus Preston de Guise begs the question: what constitutes a successful backup?
NetApp CEO Tom Georgens is quoted as dismissive of multi-level tiering, saying: “The simple fact of the matter is, tiering is a way to manage migration of data between Fibre Channel-based systems and serial ATA based systems.”
In this video, I present the shortcomings of traditional tiered storage and propose a solution: Although merely using different disk types will never deliver the goods, adding flash and cloud to an integrated, automated solution will be truly revolutionary. I look forward to the day when all of today’s buzz-worthy technologies (flash, cloud, thin provisioning, automated tiering, post-RAID) are mixed together to form a really revolutionary storage system.
As you might have read in my earlier blog post, EMC has announced the release of the first version of their product called “Fully Automated Storage Tiering” or in short “FAST”.
Now, to describe the purpose of this technology in a very simple form, we are talking about the performance of your storage and some logic […]
Simon Seagrave (http://www.techhead.co.uk/) asked, “How long do you think it’ll be before SSD will overtake SCSI as primary tier 1 SAN storage? Giving a new SSD and SATA tiered mix.”
Short answer: Yes, it will be SSDs + SAS and within 2 years.
The real quesion is when 15K RPM highspeed drives will be replaced with SSDs […]
