SLM Vs Burst RAM
Oct 10, 2009
Could someone explain in layman's terms a point on RAM for VPS? I always understood that you are allocated an amount of RAM with each plan. For example, 256MB on most lower packages. You are then allowed to reach some limit in case their is some spike and memory is required. That is called Burst RAM limit/amount. Like 1GB. I asked about this to my new host and they responded below. I'm not following it.
Quote:
SLM is a method of using dedicated physical RAM (RSS) versus a guaranteed (unknown) / burst (VSIZE). SLM is only accounting physical memory usage and you are silently swapping on the host (the VSIZE) -- in short, if you are running out of RAM it is because your VPS is physically trying to use more than your dedicated RAM limit.
SLM implements a 2nd-level out of memory (OOM) manager. In the event a VPS uses all of its physical RAM SLM will first delay the execution of processes to wait for more RAM to become available. After this it intelligently decides which processes to kill to maintain a running system.
On the kernel level it decides itself what should be preempted to swap in the system and which data is most rarely used. This is more efficient from overall performance point of view than having a separate swap space assigned to each VPS and used when VPS has exceeded their RAM limit which cause disk I/O bandwidth which is used for swapping is a scare resource, therefore it is not worth swapping out something when there is global RAM available still.

I am new to VPS and am trying to get my head around it. What I am trying to figure out now are the pros and cons of Guaranteed and Burstable memory.
Assuming everything else is equal, and both options are in the budget, and that there is a requirement (at least at times) for more than 768mb of RAM, which option is better:
1152mb Guaranteed (SLM)
or
768mb Guaranteed / Burstable to 2048mb
Obviously, a big factor would be whether or not their is RAM available to burst to, and as I understand it, that is completely dependant on the server, other VPS's running, number of VPS's, etc.
However, what I am trying to figure out is which approach is typically better. If for the same money you can get 768mb w/2048mb burst or 1152mb SLM w/no burst which is the best option.
If my current requirements are important, then I listed them in a thread titled: "If I go with VPS would vB performance suffer greatly if I add multiple sites to VPS?"
I can't truely link to it, because I have less than five posts, but here is a quote of that thread, so you can hit the button in the quote to go there:

A Xeon Quad Core 2.4 Ghz, 4 GB Ram and 2x250 GB HDD, cpanel/Fantastico and 10 MBPS shared Port,
With softlayer current promotion, I get it for 224$
With Burst.net reseller - I get it for $180
So is paying $44 more and going with softlayer worth? or is Burst network as good as softlayer?

It had an Abuse Incident over the last 24 hours and missed the deadline they gave to clean it up. Being in Australia the time differences can make it difficult to always catch an Abuse Incident. Anyway so the server is disconnected and we have to pay a reconnection fee, ok fair enough.
As soon as the server went offline I became aware of the issue and contacted their support.
They said I need to pay the Abuse Invoice, so I said ok and went to my Client Area and there was no Abuse Invoice. So I tell the technician that there is no invoice in my account, he says, oh ok there must be a billing problem and passes it over to "Customer Service".
Hours later there is still no response from customer service and my server is still offline.
I shouldn't have my server OFFLINE while waiting for them to sort out their billing problem. Them getting their Abuse Invoice paid is NOT A TIME CRITICAL matter.
A server outage is a TIME CRITICAL MATTER.
Here I am still waiting and nothing is being done, my server is still OFFLINE. I have no problem paying the Abuse Invoice, but the server outage just goes on and on because they can't seem to generate the Abuse Invoice that they require me to pay.

Is anyone else having trouble with name resolution at Nocster being really wonky? Sometimes it works fine, sometimes it times out, sometimes it takes a couple seconds.
My resolv.conf:
search hostnoc.net
nameserver 66.96.193.2
nameserver 64.191.0.2

is anyone else having trouble with burst.net at the moment? from two locations, i'm having problems where anything that will elicit a large response just hangs indefinitely. i can ping my server just fine, i can shell into it... if i do "top" or "dmesg" or anything else that might dump back more than a few lines of response at a time, the ssh session hangs. i can do "ps x" as a regular user, because i only have two processes running. "ps ax" will hang ssh.
none of my websites work, and i can't get on the burst.net website from either location. i tried calling but no matter what sequence i try for (even tried reboots) i can't get ahold of a live person, but then again it is almost midnight.
anyone else experiencing this?

I do alot of reading of select forums and contribute here and there, I am a huge contributor on Digital point. With lots of Itraders. I came here to try and find some info as to what was going on with burst.net when I stumbled across the merged thread here and started seeing what was going on.
I don't want to say it's typical but more often than not these days the server have been more miss than hit. Coupled with the fact that things like RAM upgrades carry a setup cost and a higher than avereage monthly fee. 512mb costs more than what 1GB does at most hosts.
On top of that, the upgrade time is 1-3 DAYS not hours, DAYS. My Ip address have to change for a bandwidth upgrade which caused 24 hours of downtime as the DNS propagated again.
Server was suspended 9 hours into an abuse report when it is promised 24 hours to solve the issue and I had agreed that the account needed to be suspended. We went back and forth with them about replying to the ticket that referenced the abuse issue. I was told that I needed to reply to the ticket. If they had bothered to look at the ticket themselves then they would have seen that I had a 3 to one ratio of my posts to theirs in trying to get this solved. $50 abuse fee talk about nickel and dimeing a guy. I know, I have heard it before, read the tos, aup, billing, and privacy policies. It's all in there somewhere but you just get to that point where if they charge you one more little BS fee then I'm going to go postal. Plus they can't keep their end of the bargain up when it comes to the network. Received a cpu / mobo upgrade expected upgrade time48-72 hours, after it was all said and done now the server sits still with 4GB or ram that it can not full recognize. On a happier note I did have other servers there (that's not the happy part) I knew in my gut that something had to be done. I've spent alot of time getting quotes with other providers, I even added one to my contact list from here on WHT, it was sales@hivelocity.net. I got several quotes from them and never pulled the trigger on a configuration on any of them, I tried out a few other smaller hosting companies with no luck and finally after a month or two of Dave asking how I was doing on a daily basis, I decided to go with a test server. Setup was decent, I had a problem with my ip when I first signed up, but the support staff is great, no hassles no fuss, no paying to upgrade, unless there is a price difference, NO DOWNTIME, NO ABUSE FEES (never had an abuse case yet) but it's not in any of their policies that I can read. All the chips seem to have fallen into place for me when I signed up with them.
I call Dave on a regular basis I get calls from him every so often. My server is up and better than ever. I get answers to my questions that are beyond the normal realm of technical support which I find odd because I see all over WHT that they are an unmanaged host. There are no per incident fees or nickle or dimeing. I was told by a tech that there would be a $65 per hour fee to install a 3rd party piece of software that they did not support but that to me is in the same realm of taking your car to the shop when you want a performance part installed. You want it done right and you want it quick. I still have a server with burst that I am almost finished with. I'm glad I had the courage to follow my instinct when it came time to switch or else I would be completely stuck. I ended up with burst because I was re-acuired through a reseller named Vagu. I am starting to see that there were problems between Vaguhost and Burst some time ago, about the time of that switch is when I started having second thoughts that I may need to add another provider. I am happy referring people to Hivelocity and I also resell their services. I am not too familiar with the other account representatives for Hivelocity, I believe that there are 4 total, but if you have been left high and dry by burst then give them a shout. I believe that one person even called themselves a "refugee."

I'm planning to get a small VPS (128 MB).
I've come across a XEN based plan that offers additional 256MB swap space, and a few others Virtuozzo based plans that offer bursting capability (some even upto 8GB).
Which would be the better option?
Also, in Virtuozzo, will SLM allocation be significantly more beneficial than UBC for a small VPS?
Another question ... DirectAdmin officially claims to be able to run on a minimum of 64MB RAM. How would it perform on a 128 MB VPS ?
I'm not really looking to do much, only to host a few (5-6) small sites along with some other non-webhosting applications (which is the reason for getting a VPS instead of a reseller).
I've seen most people suggest atleast 256MB for DirectAdmin, but that is beyond my budget. (I'm also seriously considering the option of employing vi as a control panel to further conserve my limited resources)

Core2Quad Q9300 Quad Core
8 g ddr2
2*1 tb sata raid 1 software
1*250 G sata
whm/cpanel included
ddos protection network level
basic support
on other hand webnx offer is $99

6GB DDR3 Ram +$25 ($150 for the 6mo term)

I have server from many providers, hetzner, sharktech & burst.
But the worse i found is of burst.net.
I have been with them since 2+ month now, but the quality of service am getting since i order has been not nice.
from the beginging server used to get crash after every 5-6 days then i need ask what happened, and they were never able to provide the reason.
i ignored it as reboot were within 15-30 minutes which is acceptable.
But since last 15 days. server has been crashing every 12-15 hours.
one of the technician said that its hard drive, (oh comeon hard drive has nothing to do with it. i will let you know later why.)
then i asked him to change the hard drive.
First they offered me data recovery package which costs some $$$.
I said ok just put os in new hard drive and attach my old hard drive so that i can take backup.
I asked them why. then they changed the whole machine with everything brand new. and attached my old hard drive
I took backup and after 2 hours its dead again(crashed ).
They never replied me within hour or so after that.
They blamed that old hard drive is causing crash.
alright i asked them to remove old hard drive and what happened? Still crashed and dead for 3 + days now.
you can have a look at whole conversation.
[url]
Just make sure whenever you do business with anyone , they should be responsive and they should know what they doing.
My contract will expire on 9th of nov, but i guess my money is already wasted.

I am a current customer of Burst for more than 6 months already and so far I am loving their service. There are very, very minor issues but it gets resolved in a timely manner. I have 7 servers with them and looking forward to expanding more. Their sales support Shawn and Benj are very considerate and their technical support Brian is very helpful, knowledgeable, polite and treats customers the right way.
Burst live chat support (AIM) is also the best I have seen with a host.
I recommend them to everybody who's looking for a reliable network and good support!

I having problem with them particular cancellation.
first, I submit an cancellation form. Then customer service wrote to me to reconsider cancel my server. So I replied my ticket and they also know I having some problem with the server that support department had wrote to me. the next day I managed to solved the problem and replied to them no need their help. A few days later when I log on to the billing system failed due to my e-mail address was not on file. So I wrote the ticket to billing department before THU 9am GMT-5 EST, Friday till sun no responded. So I wrote to support with refer to billing ticket ID and support replied to me most department like billing work only in Mon to Fri 9am to 5pm EST GMT-5. In Monday afternoon, the billing replied said my server is cancel on 07 March 08, no payment due and my billing account closed even my server is still active.
There is nothing I can do about it. If you want detail can check my web site [url]or [url] which the billing department can made this mistake for very long reply time which I not happy wrote to customer service department that I spend a lot of time effort making the server work and also other department for hard work on trying to help me providing better service to me now waiting for their reply.
I decided that you all can look a last minute visit my homepage if not a blink of an eye 7 March 08 my server will be switch off by them.

Most of us know the Sellwhm/RalphC problem, and unfortunately i'm on a side note of this. I purchased a dedicated server through RalphC a week ago, and was assured over and over by RalphC there would be no problems. Now I sure think that was a big mistake.
Roughly 4-5 hours ago my server was all of a sudden shutdown, with me on it. I waited about 25 minutes and Emailed RalphC. From there I waited 30 minutes... no reply. Jumped on MSN... not only is he not on-line, he isn't even on my contacts anymore. I jumped on WHT to send him a privmsg, and looked around at some new posts. Which then I found all these SellWhm posts...
I'm not holding anything against RalphC, and i'm sure he has some stress going on. What I would like to get is some suggestions, on what the heck I should do?
Here is the problem:
I bought the server through SellWHM.com/SellWHM.com(RalphC at the time). He said he had a business reseller account with burst.net. I paid RalphC for one of the servers, which it took about 3 days to get. I started to move some files, secured the server etc... went to run cPanel... it wasn't there. I installed cPanel myself, and the license wasn't valid. *sigh*. He contacted Burst.net and it was working about 1 1/2 days.
At this time (being 4-5 hours of downtime) I cannot get a hold of RalphC at all. He failed to give me his contact phone number, and his email and MSN are both going no where.
I contacted Burst.net via their helpdesk and opened up a ticket. Corey answered it and needs the paypal transaction ID, and/or the last 4 digits of the CC. Here is the problem: I paid RalphC, and RalphC paid Burst. So they do not have my payment information.
RalphC gave me his reseller ID number and said if I had any problems to contact Burst directly. Which I told burst in a support ticket that he did give me his ID#, and I gave them all the server information.
At this time Burst.net has yet to reply to my ticket... so I continue to wait. Server down, I paid $90.00... and here I sit.
how to even proceed.

When we first got our server (named Angelina) from Burst we were very happy with the server and managed service. However, for the last few weeks we have been experiencing downtime almost daily and sometimes twice daily. Now it has become daily and for hours at a time.
There reason is another server was flooded and was causing the others on the same block to fail. Seems reasonable enough and everyone makes mistakes and has problems. But almost every day for a few weeks now and still no permanent fix?
Our clients are threatening to leave us and we are losing money because of this. I've lost sleep debating whether to post this or not. Since we know that we will not be reimbursed for our losses we hope to prevent others from falling into the same trap.
We are currently looking for a new server/datacenter to more all of our clients from that server. We actually tried to purchase another server from them awhile back but was told they we could not keep up with orders. I'm glad we didn't get it. We cannot continue to let our clients experience this.

I heard that Burst is pretty good, so i had a try to puchase a server from them.
81 hours ago, i placed an order.(received their email)
80 hours ago, I paid the order. (received their email)
79 hours ago, I received their email asing for my account and personal info, in a word, everything except your password. that's fine, I run B2C business either, i know how bad chargeback is. I did, and send it back within 15mins.(BTW I paid with paypal verified though, but I did it as they required) 33 hours ago(48 hours passed, as they said on AD or website, ask us to expect 24-48 hours.) unfortunately, no reply. I received an email that they might take mins - 72hours) that's fine. 24 hours only anyway.
9 hour ago (72 hours passed) i asked when i can get my server. the answer is that "We are awaiting required documentation before we can go forward with this order." I sent it back 72 hours ago!!!. that's ok, there must be some mistake i made. so I transmit the original email to them and reply the ticket with the content of my email.
6 hours ago they emailed back(lucky fast) asking me attachment is unavaliable, ridiculous!!!!! I send them my info with complete text content on BOTH EMAIL AND TICEKET. 6hours passed. no response.
now when I check my order info, the invoice started from 81 hours ago. think about it, if I didn't ask, they'll keep the order period forever, until 30 days passed, i'll get nothing.
what a so-called repution company. it's my first experience on them, but I felt so bad, I have cancel my order, lets see what will happen. I don't want to say this on WHT, however, they always Stimulus my patience again and again.
Cherish life, stay away from Burst.net

which DC you'd choose from burst, sagonet, tranxact and theplanet?
I tried searching the forums, but there's not much about sagonet and tranxact.
I know theplanet pretty well (use them for the last 3 years) and they're just fine... but they're more expensive than the other 3, so I'm only choosing TP if I don't fell confortable with the others there're some complains about burst, but I know a piece of a client base will complain anywhere, so not sure I should cut them out
my main concerns if uptime and fast tech support (specially reboot/hardware)... I can take care of software problems, as long as I have a working SSH

When there are problems with the site, people may be sent to our status site. We just did that, with the site hosted on Dreamhost and it barely lasted 5 minutes (hehehe). Is there any viable host/option that could support these circumstances?
Near-zero users a day but may suddenly spike to more than 5,000/day?

How much Notice do I need to give nocster/burst before cancelling?
Not ready to cancell just yet but probably will be at the end of next month. (Moving to co-lo and as i'm in the UK burstnet's datacenter would be a bit far to travel so Won't be using them for Co-lo)
Couldn't find mention of the minimum notice period on their site.

I'm here to ask a few questions, and hoping any burst resellers/customers can possibly answer them for me.
Q1.) How long do additional Ip's take normally?
Q2.) How long do remote reboot details take normally?
Q3.) Do Staff ever ignore your tickets?
I've been waiting for both Remote/Ip's since Saturday ( was told Friday they would be sent within 24hours) and tickets being ignored by the looks
