Rolling Restart for Server 1.30

It might appear to make sense from an efficiency standpoint to have a variable number of regions per host server except for two things: Load can vary dramatically if a club, for example, has an event, they can go from 0 to 40 avatars and back again. Moving a region to a new server if the load rises means shutting it down.

This is one thing I can't agree with you.
most virtualization solutions offers live migrartion(VMware VMotion,etc) between servers without downtime(or, more correctly,with several ms of it).

You "buy" a named map region, which is a complex data construct. The Simulator is the program which "runs" the region when its up. That includes keeping track of all the contents of the region, simulating physics, running scripts, and communicating with all the users who are connected to that region (in it or can see it).

The physical server hosting the region can change at any time. Full regions normally are 4 per server (one dedicated core of a dual core/dual CPU server). Homesteads and openspace regions, which can have less stuff in them, are packed more per server.

So what you get for your money is 1/4 of a server basically, though its performance can be affected by the other regions running on the same box. If they hog all the communications capacity (to users, and to the other databases), it can affect your performance.

In addition, you are paying for a share of networking, support of 260TB of asset databases, customer support for 750,000 active users, etc. Oh, and Concierge support if you have 1/2 region or more.

Just looking at the server cost is like just looking at the satellite costs for DirectTV. Sure, they are a large cost item, but theres a lot more than just that to run a TV service, or second life, than the bare hardware.

As far as "cloud computing", SL is already a cloud type service, you get resources based on how much "land" you own. Buy more land, get a bigger fraction of the server capacity. Not in a strict "I get 5GB storage and 50GB transfer" kind of contract, but in a "I get one prim per 4.3 meters of land, and a reasonable ratio of scripts and avatars".

It might appear to make sense from an efficiency standpoint to have a variable number of regions per host server except for two things: Load can vary dramatically if a club, for example, has an event, they can go from 0 to 40 avatars and back again. Moving a region to a new server if the load rises means shutting it down.

Second, us users can write all manner of scripts, or do other things and crash the region (I have done it myself when testing something for lag). By isolating each region on a separate core, you are less likely to take out another region when yours dies.

As far as why I am I answering this, well, Im writing the SL user's manual wiki pages (https://wiki.secondlife.com/wiki/User%27s_Manual), I used to test and document software for a living, and there's 750,000 of us, and 300 or so Lindens, so in aggregate the SL users have more time and know more about it than they do, with a few exceptions like Server software internals.

Someone else that suffers from verbal Diharrea and doesn't read... I want LL to answer the question... I though I made that quite plain... clearly not... I don't want other peoples opinion, guesses and or assumptions.. I'm asking the engineer.

You are asking a software release engineer a *business* question (what do I get for my money). Why do you think you would get an answer for that?

Oh, and you are not the only reader here, the forums serve as a searchable general knowledge store about Second Life. You may not care to hear our answers, but other people might.

and suddenly you are all experts in LL's infrastructure.. have insight to their business plan and spec sheets.

and suddenly you are all experts in LL's infrastructure.. have insight to their business plan and spec sheets.. NOT..
and BTW, I'm no troll.. I was asking a question of the poster/LL and every man and his dog with an opinion gives their opinion. The 'Engineer' I refered to, was in place of the oily rag.

Okay, seriously... If you were only interested in an "official" Linden answer, why didn't you just IM a Linden, instead of posting publicly and getting all snarky when someone answers? When you post to a publicly-accessible forum, your post becomes fair game for the community to respond to. If you don't like that, then don't post to publicly-accessible forums.

I am only interested in a response from a Linden.. thats why I posted on THEIR forum... This is NOT a 'publically accessible' forum. You need an account to access it.
When I state, I want an answer from a Linden, what part of that did you miss? What's dragging this on, is the ilks of you, persisting on putting in your two pennies worth.

If you had the tiniest of ideas why I wanted this question answered by a Linden, and why so far a Linden hasn't answered this, you may wish to stop wasting time and deflecting the thread. However, it's very doubtful a Linden will answer this now, they will probably simply lock the thread.

You need an account to post on most forums. This is no less public than any other forum. Anyone from the general public can come, create a SecondLife account and start posting here. It is accessible by the general public and so by definition is a public forum.

All that is posted here is fair game for comments by anyone. It does not matter what you wanted or who you wanted to answer - it is you who needs to understand, not the other posters. You don't get to say who can answer. If you don't like it, tough, don't post as that is the only power you have. If the Lindens lock this thread it will be because of your off topic drama whoring and crying about other people's responses and nothing else. So my advice would be to STFU and let LL get this back on topic to keep us informed about the rolling restart details.

Thank You.

what's up with all this lag, my sim aint laggin and i got loads of ram and a supe connection souddenly im laggin worse than ever , i got enough compu power to play for days on ultra without clearin my cache now i cant play even on the lowest settings withought crappy lag wtf is up?

You know, I can put up with most things, but your stupid idle threats are a joke.. what exactly do you think you can do? If I want your advise, I will ask for it. If I make a comment on these forums at a particular poster, then I can expect them to respond.. not someone with time on their hands. I don't want you to respond, so move on. Your continuation of bleating, is what will get this topic locked. If you had half the knowledge why I asked this question, and the importance of the anwer from the right people, you would not be the way you are.

Publically accessible suggests non-enrollment, or giving details of who you are in order to participate. This like most forums, you have to give information about yourself, in order to read and or post here.

*** Politeness is priceless when received, cost nothing to own or give, yet many cannot afford -

LOL.. what a bunch.. where did the cracks open up and you lot swarm in..

You have no clue why I asked the question, no clue why I wanted a Linden to answer, as its a Linden Poster that made this thread, its in the Linden section and I asked a Linden for a reply... but for some reason, you have all assumed you are speaking on behalf of LL.

I have already explained this to one poster who privately IM'd me. He now sees where I'm coming from, my motives and my frustration from all the so called experts spewing forth opinions.. deflecting the question.

Report me all you like, it worries me not.

[Updated @ 11:33 am PDT] During testing, some regressions were discovered that need to be fixed and re-tested. Consequently, the 1.30 deployment has been pushed back by a week. The new times are reflected below.

We will be deploying server version 1.30.0 to Second Life during the weeks of September 14 th and September 21st . The rolling restart is scheduled to look like the following:
Thurs Sept. 17th: 1.30 deploy to pilot regions
Weds Sept. 23th: 1.30 deploy to 1/2 of agni
Thurs Sept. 24th: 1.30 deploy to 1/2 of agni
As with all of our server deploys, each region will be restarted once during one of the rolling restart periods. Most regions should be down no more than 5-10 minutes, although some fraction of the regions will take 20-30 minutes to upgrade. If your region stays down for more than 30 minutes, please contact support. Each region will receive warnings starting 5 minutes before that region is restarted.

You are right, I have no clue why you asked the question here, I don't care either. This was not the place to ask it. Period. Nobody has said they are talking on behalf of LL either, you are sadly deluded.

Nobody cares if you explained it to a hundred residents via IM who may also be a figment of your imagination, it changes nothing.

It is rare to find someone posting here that is as clueless as you about where the appropriate place to have a private conversation with the Lindens is and then become as abusive to other posters who have a right to respond to *ANYTHING* that is posted here.

We all get that a Linden made this thread, so what? Do you really think that the conversation on this thread is supposed to go from resident to Linden and Linden to resident only and resident to resident is somehow prohibited? I suggest you read *every* other Linden initiated thread to find out how off base and deluded you really are.

Now if you are done derailing the thread, can we please get back on topic?

everyone stands up and shouts "WRONG THEATER!"
