hard drive sizes

by Russell Coker

http://en.wikipedia.org/wiki/Hard_drive#Capacity Currently the biggest available 3.5" SATA disks are 4TB according to Wikipedia. Has anyone seen announcements of bigger hard drives? One of my clients has a zpool of 3TB disks that is at 79% capacity so it's time to start thinking of adding more capacity. Upgrading from 4*3TB to 5*4TB would be barely worth doing. But upgrading from 4*3TB to 5*5TB would more than double the capacity and thus be a better option than buying an external case for adding more disks. So I'm wondering whether 5TB disks will go on sale before my client runs out of space. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

It was MOOS 1600(RSX-11 compatible), not Unix. There was MUTOS available, a Unix (System 7?) but it was not installed on the machine we used. I do not remember whether RSX-11 had a "nice" but I am sure we did not use it in the first week of studies. I read a book about the internals of RSX-11 short time afterwards, it was a copy on a microfiche. It was quite difficult to get a hand on literature like this when living on the wrong side of the Iron Curtain. Regards Peter

From: "Duncan16v" > Oops. I stand corrected. PDP-11/74 then PDP-11/80 > > http://irse.org.au/index.php/en/component/docman/doc_download/569-metrol-co… I keep an half inch tape from a K1630, an East German PDP-11 clone. In the first week studying back in 1987 they gave access to a K1630, three students at the time. They shared the CPU and 256kByte of RAM. When one started compiling the editing became slow, when two compiled the third student could go out for a coffee. When you were patient enough to endure it they gave you another challenge, a GD-80 vector graphics system from Hungary, looking like a radar screen and programmable with Logo and Turtle Graphics. After that you were qualified to use faster equipment. Amongst others we had two VAX-11/780 then, using Schneider PCs with a VT-320 emulation. The K1630 retired in (Northern) spring 1990. The paper strips were used for the carnival. That was its last job I know of. We just had a new building finished when the wall came down. The K1630 was already planned to stay behind and not to move into the new house - and the donations from the West (introducing SPARCstations, HPs, DECstations to us) were the final nail in the coffin. Unbelievable to find PDP-11s in use, here and now! Regards Peter

Intel processor confusion

by Brian May

Hello, Looking at these pages: http://ark.intel.com/products/codename/67456/Ivy-Bridge-E http://ark.intel.com/products/codename/29902/ What does "Formerly Ivy Bridge E" and "Formerly Ivy Bridge" mean? Are these 3rd generation/Ivy Bridge? http://en.wikipedia.org/wiki/Ivy_Bridge_(microarchitecture) Or 4th generation/Haswell? http://en.wikipedia.org/wiki/Haswell-E Reason for asking is that I am looking purchasing a computer that is advertised as using 4th generation chips, and it uses "Formally Ivy Bridge E" chips. Which appear to be 3rd generation not 4th generation. I contacted the seller and got a response that confused me even more (they are based on 3rd generation Ivy Bridge E but released as 4th generation??), so just trying to work out what the situation is. Thanks -- Brian May <brian(a)microcomaustralia.com.au>

Boat people somewhere else

by Petros

http://www.bbc.co.uk/news/world-europe-24380247 "At least 130 African migrants have died and many more are missing after a boat carrying them to Europe sank off the southern Italian island of Lampedusa." It is one of the worst such disasters to occur off the Italian coast in recent years; Prime Minister Enrico Letta tweeted that it was "an immense tragedy". The government has declared a day of national mourning on Friday. "There is no miraculous solution to the migrant exodus issue," said Italian Foreign Minister Emma Bonino. "If there were we would have found it and put it into action." The number of those arriving by sea to Italy this year until 30 September stood at 30,100, according to the UN. --- Regards Peter
