Today ( Friday 27th July ) is sysadmin day, and we at Majestic would like to say thanks to our Systems Manager, Chris, and the specialists at our datacenters for the ongoing work that keeps our massive world wide crawl effort operational, and our web based services available.
It has been said that a picture is worth a thousand words, so Majestic would like to present a picture taken at one of the routine maintenance visits to the server farm, with the upgrade of memory in some of the servers. The chips below represent around 2TB of memory – we will leave it to you to figure out how many networked Apple II microcomputers would be required to fulfil that sort of capacity.
Steve has been engaged with the Birmingham tech scene for years, co-organising the grassroots open-source conference YAPC:: Europe 2008, and founding the West Midlands Java User Group in 2014.

Lets see… 192 sticks, each with 2TB. Thats 284 TB of memory. If I remember correctly, Apple II computers had 64kb of ROM. Thats about 4 trillion Apple II computers. Nice job guys, keep up the work. Maybe one day I’ll be using the Majestic Search Engine.
July 29, 2012 at 1:21 amActually – each stick is 8GB, making a total of 2 TB. 8GB sticks of RAM is as large as they currently come.
July 29, 2012 at 11:05 amActually there are 16 GB and 32 GB sticks but they are often less cost effective than 8 GB ones.

July 31, 2012 at 9:23 amOur memory is state of the art server ECC variant, it won’t work in laptops I am afraid 🙁
July 31, 2012 at 11:35 pm> Yeah, In general, laptops do not use ECC memory. You will not find ECC memory on any retail laptop model, meybe only in military-spec models.
August 15, 2012 at 9:39 pmHow many GB has the main server? 512GB? 🙂
October 19, 2012 at 3:00 amI’m not sure I’d say we have a “main server” – a lot of the work is distributed. As for the memory sizes in the farms – it varies, though I can safely say that it’s a fair bit above the 640k limit found on early desktops 😉
