building a mass storage server, but unsure whether it is better to go for most space per system, or most space per U.
Looking at making 2 storage servers sometime in the future, one more for performance (15k 300gb SAS drives) and another for more storage (bunch of 1TB SATA drives). Both would act as iSCSI targets and likely have multiple gigabit ethernet connections bonded together.
Some options I am looking at:
1) HP DL320s provides 12 drives in 2U, or 6 drives per U. Upgrade it to 512mb batter backed cache and it does RAID6. Probably the densest storage U.
2) Supermicro has a 3U chassis that does 16 drives, or 5 1/3 drives per U. Pair that with one of the newer Areca SAS controllers and up to 2gb onboard cache and it should scream.
3) Supermicro also has a 3U chassis with 15 drives... just 5 drives per U, though it is ~$200 cheaper than the 16 bay one. Probably a mute point, since either way, it is less storage per server and less storage per U.
4) Get a simple 1-2U case and use external JBOD enclosures. Could put in multiple RAID cards, hook it up to multiple 3U 16 bay enclosures, and really squeeze in a lot of storage per server.
Anyone else been in a similar boat? Overall, not looking for a real dense configuration, with like 10-20 servers of this config, so don't *need* to squeeze in more TB per U, but it is one way that I've been looking at it.
Perhaps, in a way torn between the pre-built DL320s and the white label Supermicro approach. DL320s is a nice packaged system, support, iLO, etc. Supermicro allows more space and likely more performance (Areca likely better than the HP SmartArray), but no iLO, no single source for support, etc.
One of our servers was incorrectly set up before migration occurred. Now the ns records are incorrect on many domains' zone files. Does anyone have or want to let me hire you to write a script to change all the ns records and that are currently ns1.something to dns1.something. It can't be for every domain on the server, just the ones pointing to the incorrect ns, as some of them are correct. Linux server.
I have a website with a 70,000 user email subscriber database. we currently send all emails from a dedicated mail server sitting in our office. its very old, unreliable and our emails are constantly going to peoples junk.
i've looked into things like campaign monitor, which looks great, but our custom made email system is already in place and all we really need is a dedicated and safe smtp server to use for the actual sending of the mail.
i've looked at things like SMTP2go which i have used when overseas and works great, but i'm looking for something more designed for sending of mass mailouts, as well as the day-to-day emails sent from the site (signup confirmations, forgotten password reminders, etc)
I'm completely torn on going the absolute budget route vs spending more for something that'll allow easy upgradeability in the future. I basically need lots of space but file sending-- media like mp3s, video, etc.
it'll be raid 5 and I'll need at least 2-3TB initially but the ability to expand would be nice.
option 1: nice chassis with plenty of hotswap bays with sas expanders expensive sas raid card
option 2: cheap chassis to serve "immediate" needs and go with more later. not sure what I'd use as a card? maybe even onboard?
regarding reliability: I once saw a database of failure rates of different models. raptor was the most reliable of the "desktop" drives. anyone have the link? I'm wondering of the seagate ES drives are worth the extra money vs the non-ES drives. they're supposedely more reliable and the "server versions" of sata drives.
I have a question if it is possible to use my local server as database storage and even some uploaded files. I am planning to host my website even in a shared hosting server provided that I could used my local server as data storage.
We are puting together a Linux Storage server which will have 4 x 1TB SATA Hard Drives connected to Hardware raid configured at level 10.
We plan to use this box initially for NFS services but in the near future iSCSI targets so would like to make a setup optimal the first time.
What is the best way to layout the drive partition’s for this setup? My thought is
-100MB /boot ext3 -Rest in LVM --LVM Group ---LVM001 2048MB SWAP ---LVM002 10GB / ---LVM003 500GB /nfs ---LVM004 500GB /iscsi
Is this an efficient setup and provide a great deal of flexibility down the road? We will end up having more than one iscsi target running on this box in the end. Also does LVM experience a performance hit ?
I'm building a storage server out of spare parts that are lying around here at the office. Purchasing a brandnew server kinda overshoots it's target, since all basic hardware is available lika a big Chieftec 4U casing with 2x 4drive SATA hotswap bays.
The machine will just be dumb storage for saving our backups.
The plan is to add a decent serverboard, proc and some ram as a baseline. On top of that a 3ware 8-port RAID-controller with 8 1TB harddrives (seagate has some nice ones).
Now the only issue i'm having is powerconsumption. The case has an 460W PSU, but I'm not sure if that's enough.
I have found SL can offer you 12*1 TB drive based systems, after RAID-5 and Win 2003 install you get just over 10 TB of storage. The monthly price works out to $1000/Month.
I know some time ago LeaseWeb offered these type of storages....any one else know of any others ?
We are going to offer web space to our students and we want to build a new server just for this purpose. We were looking at buying a storage array, a RAID card, and a server. I have no problems building a server; however, I have never built anything with an external enclosure. I am thinking about buying this storage array:
I have a VPS and about 140 accounts on it. I'm moving to a new host, but the thought of having to move all these accounts manually really makes me lazy I have to go into each account and go to backup -> backup to remote FTP.
Is there any way I can mass backup all of my accounts, or all accounts I select, to a specified FTP server?
I have client who wants to send out a few hundred thousand emails once every week. They are into educational stuff and have these many subscribers.
I was wondering if there is any hosting available for this kind of mailing. I have the script buts its just my current host has limited mailing to 50 mails per shot and maximum 500/hour
I would have gone for dedicated or vps but I am completely ignorant about it.
im currently in the process of movinmg most of my clients MySQL dbs to a dedicated mysql server (direct private lan link so speed/bw is not an issue) but i have ~2900 .sql files i need to restore, anyone got any idea how to automate this restore,
the sql files were created suing mysqldump on old server so have all the appropriate create database entries etc but id rather not have to do each file by hand or ill be here for months
Every month or two, we like to send our members a newsletter-type email which just informs them about what's happening over in our website and community. We have over 350,000 accounts registered, so there's quite a few emails to be sent each time.
I'm currently using cPanel with Exim and SwiftMailer to send the members an email through PHP. The way I do it currently is import all the email addresses to a separate table then email 500-1000 at a time. This is controlled by a Cron job.
I'm finding Exim to be extremely slow and the queue has built up to 190,000 as I type this (the email process started last week).
My question is this. What's the best software, whether it be a program or a script of some form, to send an email to such amount of users? Or if anyone knows any way to 'tweak' Exim to handle such mass-emails.
What command do I use to mass extract a bunch of .tar files? I have a directory with about 60+ .tar files that I want to extract at the same time instead of doing it one by one.
I'm hosting with CoreNetworks (very happy with them) on a Windows platform. One of my clients has a 500-person email list. When they try to send using Outlook, the get the following error:Sending and Receiving' reported error (0x800CCC0F) : 'The connection to the server was interrupted. If this problem continues, contact your server administrator or Internet service provider (ISP). The server responded:? 1 Too many bad commands, closing transmission channel'
They didn't have any problems with sending from the list before, when I was in a shared platform with AIT. Ideas as to what the issue could be? I've done some research but can't seem to figure it out.
to rename about 1100 files from SSH. The filenames contain (, ), and spaces, and I'd like to eliminate all of those characters. Can this be done with a simple command?
I'm currently owning a website with little less than 500,000 users. Many of these users have been asking if I could send out updates about the site per email, like once per week or preferably once per day.
I'm not sure about the best way to do this. I did some reading and some people seem to suggest to get an extra dedicated server to send out the emails. Others say it's best to use a cloud service with SMTP relay, while I also saw suggestions to use a website like [url]
I have checked into mailchimp, and appearantly this whole thing will be very expensive if I want to send out email to so many users. I'm not an email marketeer and neither do I sell products, so the profit per user I would email is probably low. The primairy reason I want to send out updates is to keep my current memberbase happy, and to get some older inactive members to become active again. We had our site totally reworked recently, and it would be nice to let people know about that.
I also like to know if it's possible, in any service, to somehow unsubscribe users whos email addresses are no longer valid in an efficient way.
Some more facts:
- Those 500k users are 250k effective emails. The other people have never subscribed on registration, are blocked for misbehaviour on the site, or have unsubscribed at some point.
- As stated above, people have to subscribe upon registration. The checkbox for this is unchecked on default
- The oldest users in my database are 3 years old, so there is quite a chance emails might be no longer active.
- There are many scams in the industry I'm active in (survey panel). As a result, users are sceptical, and sometimes use alternate email addresses for registration. I believe that as a result of this there is a higher chance the email is nog longer in use than on other sites, although I have no stats of other websites to compare with.
- I once tried to send out email to 75k users on my current dedicated server. As a result, Yahoo deferred my emails (which caused trouble for the verification emails we send out upon registration). I contacted Yahoo and they whitelisted my server, but I don't feel like trying to send email from my current dedicated server again. Not to mention that the server had a lot of trouble sending out so many emails, the server load was really high while sending out all email.

We have 1,090 products and 60+ categories so some form of .htaccess trick would be amazing to know. What I could put in the .htaccess to accomplish this.
Has anyone pulled off a mass server move during the middle of the night? We have decided 350 E Cermak is where we want to be but are still working out the details of where we want to be in the building.
While the final details are being finished, I need to come up with some kind of plan to pull the move off with the least amount of downtime. Our current dc is about 4 miles away from 350 Cermak and we have approximately 50 servers to move. I plan on leaving a linux box around to redirect any traffic that is ignoring TTLs.
I was thinking the best thing to do would be label and remove all harddrives, then see if a moving company could put the servers on palettes, wrap them, and move them to 350 E Cermak. Not sure if a moving company would work in the middle of the night or not.
Courier services are pretty much out. Anytime we have had a courier service move anything not in a massive box with padding, it gets bent or broken.
I have broadband from cable company and they do not let me send mass email (over 100) at one time. I guess on top of that Web Hosting company (having my domain) has some limit to use smtp.
I want to send text email (not HTML). I do not want to use Email marketing companies (as many suffix their brand in message) and perhaps ripe good benefits via viral marketing at subscribers' cost.
Option - A =========== I am thinking to use desktop (if technically feasible) and want to use mass smtp with VPS hosting company (if they are open), within their TOS though.
Can VPS somehow be used (for mass smtp) without relocating my domain to new VPS?
Would there still be an issue as I will be using Desktop and routing emails through cable's as cable's company's limit will still be enforced?
If answer is yes, I guess I am left with no choice but to use Web server based mailing solution.
Option - B ==========
In that case, I guess something like phplist needs to be used.
Then my web hosting company would still not be open to use their smtp (or might have set some limits on smtp), so presumabily some blending (using phplist on my hosting and mass smtp on VPS) can be tried.
Solution? =========
Am I thinking correct? If not, please give me some pointers to bring me to right track.
Any recommendation about VPS who may be open to mass smtp.
I am purposely not mixing multi-threading yet. QMail is default email s/w with my hosting and I guess VPS might also have qmail.
