- Hello Stephen, Great post. Is the new IOps number on a per ESX server, per VM, per HBA? what is the unit of encapsulation? Also, is the PSA framework availabe for NFS data stores as well - an NFS...
- Very nice, Stephen.
- Did you try the update on the mail application. The middle one between new and whatever... this will force the server to check for new mail.
- Stephen: I did a google search on Exchange reconciliation on the iphone and one of the results was your page here. I have a question that I cannot find an answer to. I have no issues with EAS and...

Anyone paying attention knows I’m not particular sanguine about the near-term prospects for solid-state disks (SSDs) and hybrid hard disk drives (H-HDDs) in the enterprise storage space, but I’m not foolish enough to discount them entirely. With that in mind, it

Just a couple of quick notes. Adtron actually debuted their SSD solutions before PQI and SanDisk (http://www.dailytech.com/Adtron+Announces+160GB...) with PQI stating they were going to bring 256GB devices to the market. It's all marketing, for sure, as channel availability is absolutely abysmal and cost factors per GB are exhorbitantly high.
Also during the past couple of years, I was fortunate enough to have Van Smith (VIA EPIA platform engineer) provide a FileCopy utility that allowed me to generate scalable file size (text) and do as many reads/writes from source to target as possible. It's a great tool for judging the longevity of SSD devices (or NAND in general).
Anyhow, thought those were interesting side points! Keep up the good work!

SSDs also consume dramatically less power per I/O than convential disk (obviously) and with power being a continual focus at EMC and other companies, it does play very handily into that message.
and for the novelty side of things, may i present the Gigabyte Go-Ramdisk-box? (http://www.dailytech.com/article.aspx?newsid=7563).

As for power, note that the SATA interface takes up half a watt on its own, vastly reducing the power and heat benefits over spinning media. Put it on SAS and it's even worse! True, the chips are efficient, but the interface isn't.
Which leads me to assume that any enterprise use of NAND will be in a proprietary form, not a commercial interface like SATA.
Thanks for reading and posting!

definitely interesting points on the power consumption end. I'm curious to see the positioning of SSDs versus the 2.5" Enterprise drive push we're seeing from Seagate, et al. right now. Obviously, capacities are somewhat limited on the 2.5" drives, but slowly, capacity parity is being reached (250GB SATA drives were announced by Hitachi and Fujitsu recently). Obviously, 10k/15k spindle units will have more power draw than the 7.2K SATA units but, i suspect, when the I/O per watt breakdown is considered, these drives might be more efficient than SSDs.
