Now lets talk about the 'latency deny'ers' First of all, the say, there is no standard measurement of latency.
That isn't complicated. Sun includes the transfer time in latency figures, other companies do not. THen latency deny'ers say, there is no way to compare the numbers. Thats what I'm getting from reading the thread. Well, take a 4k block size, the transfer time isn't significant. When someone publishes their 'best' latency times...transfer time is not significant. You CAN compare latency specs. If a latency deny'er says you can't; ask yourself why. Is it because they wouldn't be favorable in a latency comparison? Some say, latency is not important in flash. Well why would someone say that? Is it because they don't have good latency numbers? The F20 card, has some features to its merit, but its not a high performance card...its not in the class of a Fusion-IO or TMS RamSan-20 in terms of IOPS. However, it has some features you may like. I understand its bootable. I'm told it has a supercapacitor. Its not rotating hard drive slow. Furthermore, if you need high sequential transfers, it seems to have that. High IOP card? Well, I do say, watch out for scaled results that look good on benchmarks. Your real world application better run like a benchmark. -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
