Virtualization has disrupted the I/O path, reducing the value of enterprise storage arrays. But all is not lost: An effort is afoot to make things right by increasing communication between hypervisor and array and demultiplexing data before it is stored.

Virtualization is a disruptive technology in every sense of the word. By abstracting and simplifying physical resources, virtualization enables dynamic utilization. But this â€œtranslationâ€ from physical to virtual disrupts the assumptions that enable performance and flexibility of physical devices such as storage arrays.
Seagate just responded to Western Digital’s acquisitions of Hitachi’s Global Storage Technologies subsidiary by acquiring LaCie. The â‚¬49 million transaction solidifies Seagate’s presence in the retail space, especially on the Apple side of things. In this way, Seagate will use LaCie to offset Western Digital’s G-Tech offerings.
This old-fashioned, predictable storage I/O path was deterministic and decipherable: The server, the switch, and the array all had enough information to do their jobs effectively and efficiently.
Storage arrays are big, expensive, and difficult to manage. Plus, concentrating storage in a single device puts everything at risk if there is an outage. So why buy a storage array at all? Arrays do a few things very well, and this often makes up for the difference, on balance.
The difference between traditional compression and modern data deduplication is somewhat hazy. And it doesn’t help that various implementations fall all along the spectrum from “mildly interesting” to “cutting edge!”
I love cars, but I hate buying them. The car buying process can be a catfight or ripoff, and it’s never fun. That’s why I was pleased to hear that Ford offers â€œfriends and familyâ€ (X plan) pricing to shareholders like me. But it’s been awfully difficult actually getting this benefit!
An obnoxious meme has returned to the fore lately, claiming that innovation is dead. The hippies did it, or maybe it was the Internet, or even a decline of America. But nothing could be further from the truth, and statements like this make me question the perspective of the speaker.
We’re taking my Building Virtual Infrastructure presentation to Columbus Ohio at the end of the month. Cool! I live in Ohio, and don’t get much opportunity to speak at events here. There’s also Backup Central Live! with W. Curtis Preston the next day, if you want to go to both!
I’ve always loved my Wi-Fi iPad, but the Verizon LTE iPad (third-generation) is too awesome to overlook. Apart from the â€œretinaâ€ display and voice dictation, the killer app is unlocked roaming on just about any carrier network. Yes, you can use your Verizon iPad Verizon iPad on AT&T, Vodafone, or even Verizon!
