Your Usable Capacity May Vary - Chuck conducts a thought deployment comparing EMC, HP and NetApp usable space for a 120 disk Exchange deployment. And while he glosses over a couple perhaps non-minor issues (RAID-5 vs RAID-DP and whether EMC’s snapshots are adequately performant), he does hit one of NetApp’s weak spots dead on: [...]
Amazon’s much-awaited Elastic Block Store for EC2 is out this morning; I’m excited to give this a try. A couple downers from the announcement: The pricing is somewhat high - $0.10 per allocated GB per month plus $0.10 per 1 million I/O requests - and the reliability isn’t where I’d like it to be. [...]
Since Sun and Amazon removed the limit on the number of OpenSolaris 2008.05 instances able to run on EC2, I’ve been curious - and a little bothered - by the fact that the 2008.05 AMI is 32-bit only. Curious because OpenSolaris shouldn’t have any issues running on a 64-bit EC2 instance (there are other [...]
Less known Solaris Features: CacheFS - Joerg Moellenkamp at c0t0d0s0.org offers another installment of his excellent Less known Solaris Features series. Of note: “In the recent days there was some discussion about the declaration of the End-of-Feature status for CacheFS which will lead to the announcement of the removal of CacheFS. After a few [...]
Part III: Since NFSv4 is Stateful It Must Be Less Robust, Right? - “This should conclude my series on this topic, but obviously it’s my blog and like any content provider with no self-respect, I am free to make as many sequels as I want in order to milk the topic for all it is [...]
Performance Report: Multiprotocol Performance Test of VMware® ESX 3.5 on NetApp Storage Systems: A complementary whitepaper to VMware’s own work comparing Fibre Channel, iSCSI and NFS as storage protocols for VMware ESX. (Seen at blog.scottlowe.org.)
According to a blog post on blogs.sun.com, the capacity limit for OpenSolaris 2008.05 on EC2 has been removed.
The blog entry makes it sound like you no longer need to register with Sun to use OpenSolaris on EC2, but that doesn’t appear to be the case - I only see the AMI in my private instances, [...]
So I returned from a little five-day weekend to sunny Lake Chelan and the Columbia River to an RSS reader bursting at the seams with new posts. By far the best post was one later deleted:
Amazon Elastic Block Store goes live! (Yeah, that link’s dead - like I said, it was later deleted.) [...]
It’s summer, apparently everyone is on vacation, but, quietly:
NetApp releases Data ONTAP 7.3 GA!!! Note that it’s a GA, not GD release; release notes are on NOW. (Seen at blog.scottlowe.org.)
It’s been a while since I posted about my unhappiness with NetApp’s FAS2020. And while we’ve replaced our 2020 with a 2050, I still get a lot of traffic to those pages, and a few emailed questions from prospective or new 2020 owners asking about the so-called 8TB limit. Here’s a summary of [...]
