Tripp Lite Versus APC Power Strips
Nov 13, 2007
I usually use APC power strips for 1U applications. I usually mount them in the hot aisle, with the outlets facing out (into the aisle).
But Tripp Lite has a few models that APC lacks (like a 1U 30A 120v with 24 5-15 outlets, or a 1U 208v 30A with both C13s and C19s).
Does anyone use the Tripp Lites, and if so, can the mounting ears be flipped around so that you can mount the outlets facing the aisle, flush with the rails?
Any other comments on relative features/quality between APC and Tripp Lite?

if anyone has insight or comments about Fusion-io's ioDRIVE versus their ioXtreme drive. If you do, I would appreciate reading your thoughts on this.
The ioDRIVE is their enterprise product while the ioXtreme drive is being marketed to the consumer market. Both seem to be extremely impressive products.
My main question is whether or not an ioXtreme is suitable for web server use. The ioDRIVE is made for server use and is much more expensive, so is not only a bit less attractive because of the cost but also a bit out of my reach, financially, at this point.
So, what do you think about the ioXtreme being used in a web server? Any reason that this might be a bad idea?
Would Intel's X25-E be a better solution than the ioXtreme? The ioXtreme is PCIe based & the X25-E is a SATA drive.

I have a 'complex' situation, if you will. The site I run has free access to a variety of server hardware. Sitting under my desk, I currently have:
1. Dual Xeon 5345 (quad core, 2.33GHz) with 8GB memory, mid-tower
2. Quad Opteron 8xx (dual core, 2.2GHz) with 16GB memory, 3U
3. Dual Xeon 5160 (dual core, 3GHz) with 4GB memory, mid-tower
We also have the appropriate licenses for Windows and MSSQL (which is what we use).
I am currently on a shared host that we'd like to move away from. We would like to have the ability to run both a production and a development environment. We'd also like to be able to offer web-hosting to a couple of other small sites...
So what I'm wondering is whether it really makes sense to colo. Honestly, it seems like we'll get a lot more bang for our buck versus dedicated. Most dedicated servers that are under 200 could only be described as sad and pathetic. However, they may be enough for what we need....

do dual power supplies use more power than a single supply?
E.g. Say I have a server than uses two amps, powered by a single power supply. Now if I switch to a dual supply (and say each supply has the same efficiency rating as the single), does my server use more power? How much more?
My simple view of this is that it probably does, but maybe not much. The second power supply consumes some power itself, but since its not under load, it doesn't consume much. Therefore, my server with redundant supplies might use 2.1A or 2.2A.

I am getting into the dedicated server market and have a question...
I would like to get access to an entire Class C so 111.111.111.xxx - is that standard or should I assume someone offering a dedicated server with 1 IP only is giving say 111.111.111.1 ?
What would be the cost of being able to allocate different sites on the same class C?

We just recently were kind of forced to go from a true dedicated server to a VPS type server and my question is a simple one.
When it comes to SQL databases is the VPS powered server just a secure as a dedicated type server?

For a server with Xeon 3060 + 2 Gigs of RAM, which setup result would you choose to run at?
This is the normal load. At peak times, they would be more like:
Server Load: 0.07 / Memory Used 50%
Server Load: 0.40 / Memory Used 30%
Would a slightly higher CPU load be a better choice than having 50% of RAM used? We can choose either scenario based on installing eAccelerator, a PHP cacher.

I visited the colo space (1 cabinet) we obtained through an Equinix reseller. There was some confusion as initially we were going into DC2, but they put us into DC3 as that's where they had the space (they have a lot of cages in both DCs).
In the past, I had visited DC2 and it's clear the facility was purpose-built for Equinix. You can tell just by looking at it from the outside, but also inside.
Driving up to DC3 (on Chillum Place), I was first surprised to notice glass windows on the outside of the building (they have the reinforced walls inside of that I was told).
Apparently, the building was some other company's datacenter or offices, which Equinix then refitted their standard-build datacenter inside the building. They also have different man-traps (like a rotating door) compared to DC2, raised flooring (which is not used I was told), and lower ceilings.
I drove around the DC3 building, and the other half of it appears to be some other company's datacenter (based on the generators on the roof). Any idea who that is?
Is DC3 the same quality as DC2? It didn't quite "feel" like the quailty of DC2, but that's just an impression and not based on any empirical evidence. It's also a bit further out there, while DC2 and its new "siblings" (DC4/5) are all adjacent to each other (on Filigree Court).
With the reseller we are using, most of their bandwidth in DC3 cross-connects to their network equipment in DC2, and that's where they peer. That's another thing that makes me feel like DC3 is quite secondary.
Are my feelings unfounded, or should I push our reseller to find a cabinet for us in DC2?

Does anyone have input on either of these VPS hosts? Their plans are similar and prices are nearly identical, and I'm trying to figure out whether I should just flip a coin, or whether one edges the other out.

I was wondering which location is better for colocation?
Is one better than the other as far as bandwidth, power or accessibility?

How much faster is a Raptor 74GB 10,000rpm compared to a Seagate 250GB SATA-II 7200rpm? Both are priced the same. I'm comtemplating on which one to use for a database..go for more storage or a faster drive.

I'm in the process of preparing to install CentOS 5 on my server, and was wondering whether most people recommend going with the 64bit version or sticking with 32bit. My server's CPU is 64-bit capable (Xeon 3060 at SoftLayer), and I have previously run CentOS 4.4 64bit on it, though I did have some struggles from time to time getting things to work (following setup guides that tend to assume 32bit more often than not).
I'll be running just a standard setup of PHP 5, MySQL 5, and Apache 2, powering several moderate-traffic sites that run on the Drupal CMS (e.g. about 7000-10000 visitors per day total, though hopefully more in the future of course). I don't plan on running a control panel other than Webmin, though I might get DirectAdmin or similar in the future to make hosting some friends/clients a bit simpler.
Will going with 64bit offer any worthwhile advantage with this setup?

I am having trouble working out which host to choose for a new project.
I usually opt for Webmania or Heart Internet - they are excellent providers but Webmania now applies a bandwidth cap that may be too low and Heart's cheapest package does not provide sub-domains. I can't be sure whether 12GB will be big enough for a site that will contain galleries of high-res images (I have no prior experience with caps and traffic predictions are impossible at this time) and to get sub-domains from Heart means a £90 per year package (too much).
Streamline is one of the few good-value providers that do not cap bandwidth, but I have concerns about the effect that this may have on server speed given that it is bound to attract the kind of sites that are really heavy on bandwidth. This point was mentioned in an article recently.
If I take the last option, will I be hampering the performance of my site?

I have a lot of experience with VPSs and recently have been working with dedicated servers but my partner and I are going to be providing VPSs and my main concern is securing the node the VPSs will be on. Would I secure it like a normal dedicated server?
I'm worried that if I secured it like I would my dedicated servers it would affect the VPS clients hosted on there. Any assistance is appreciated, even if it's just a recommendation for a management company or single user who could assist us.

price wise I could switch server.
Currently:
Intel(R) Core(TM)2 CPU 6700 @ 2.66GHz
2 core
Ram: 2GB
to:
Harpertown E5405 2.0GHz
4GB
quad core
RAM: 4GB
I'm not sure the quad core runs with 2.0GHZ versus 2.66GHz.
CentOS 32 bit.
all sites currently on the 6700 using mysql, server load in WHM shows ~1 (2).. just full weekly backup pushes it over 4.
Would be nice if somebody could comment.. would be the E5405 with 2.0 GHz faster, worth switching?

Both are 1U machines with 1G of memory, 2000G of bandwidth, 160Gb harddrives.
Is there a significant difference in cost between these two servers?
Is there a significant diffence in power consumption between the two?
Is there a signifcant difference in cooling between the two servers?
Is there a signifcant difference if rackspace requirements?

Almost all dedicated server providers offer windows 2003 server free. Any suggestions to choose one way or the other?
Any major limitations either of these cases? I never worked on linux before, have basic experience on unix though.
Please compare reliability, resources (if problems) in terms of cost, extendability, etc.,
Does cPanel support windows?
I am thinking of limestone 8gb Q9300 server (64bit) with their 30% off deal.

I'm a (mostly SQL and Java) programmer by trade, I have an MSc. in Computer Engineering, and for almost 8 years I have done web and database programming on the side. I have a site (www.the-athenaeum.org) that has had its ups and downs. Sometimes I find lots of time to work on it, other times life intrudes and I neglect it. It gets a few hundred thousand hits and maybe 30,000 unique visitors per month (or so).
Long ago, I decided (for reasons of security and some idea of the nobility of open source) to go with FreeBSD/PostgreSQL. I went from crappy no-name hosting to CanHost to LayeredTech, teaching myself the OS and db from scratch in little scraps of free time. In general I have always gone the cheap route by necessity. I'm determined to keep my site nonprofit, so I've never had banner ads or Google ads. Over time as I made more $ in my "real job" I could afford slightly better servers.
These days I could probably spare $200 per month out of my own pocket to subsidize my hobby. We have a new partner who may provide another $200 per month or so.
I have come to a point where my lack of knowledge is probably holding us back. It's a one-man operation from a web/db-programming standpoint, and I am finding myself using too much time on anti-hacker and server-optimization activities. The server runs slowly. People keep spamming my PunBB install. I am trying to keep the server up and responsive instead of adding new features and finding new users. My cheapness is biting me in the butt. I think if the server ran smoothly when people came, and if I could spend my time adding the cool features I dream of, we would double or triple our user base pretty easily.
I suppose you could sum up my operation by saying that I have a web site that "does cool stuff ... slowly."
I figure I have two possible routes:
1. Pay for a "semi-managed" server or a managed server: By this I mean having someone set up the OS to be very solid, someone who can look into why the server is so sluggish and fix it. Someone who can give me an SLA that deals with spamming/hacking. I don't care about admin. panels and the like, but I do need a solid, fast server, or at least one that performs up to its basic potential.
2. Have a "geek on retainer": Instead of that, pay for targeted services. Pay a FreeBSD guy to do the initial server setup. Pay an Apache/PostgreSQL guru(s) to get the basic infrastructure in place. Pay a PunBB mod developer to harden the forums. Bring them back in when specific problems come up.
I've learned a lot over the last few years, but I will never become the expert that is needed to fully grok the sys. admin. tasks.
Which route would you recommend, or is there a better way? How do I price out these services?

With Windows 2003 server, there are comprehensive lists of what you need to do to secure the server before use. For Windows 2008, I wonder is there such a list? Or is it true as what I heard from Microsoft that it is already secured out of the box?
Anyone has any resources on the hardening or preparation of 2008 for server hosting uses?

I just ordered a server which has that setup:
AMD Athlon 64 X2 6000+ Dual Core
8MB RAM
2x750GB RAID 1 HD
Now I wanna run it with DirectAdmin, but obviously DirectAdmin doesn“t support the Debian 64 which is installed but only 32 bit Debian.
Now I wonder wether I could setup a Debian 32 as well on that system and if yes, wether it would give me a deficit in Performance?
Or would you rather go with CentOS 64 which Directadmin supports?

I just signed my agreement for 2 cabinets at Internap's Atlanta CoLo. For now, I will just have 1 120V 20A circuit in each cabinet.
At my office's server room we currently have 8 circuits I am powering my 2 racks from. I am just curious how many servers you can typically put on a 20A circuit. I am also considering adding two additional power feeds (1 more for each cabinet) to have truly redundant power for my dual power supplies.
I am hoping that 20A is plenty for my needs. I have around 20 HP and Dell systems. Mostly HP DL380s and Dell PE2950s.
Any ideas? I am splitting them in half, only filling up a half of each cabinet for now, as we are growing quickly and I wanted to overguy space so I would not be forced to add another cabinet later and have it end up somewhere else in the DC.

I wonder if any colocation providers here have any tips for measuring power. Currently I'm using APC 7900 power strips with amperage meter. I'm not a power expert by any means but I want to be able to calculate whats the cost having a server drawing 2 amps 24/7 365 days week.
Our secondary site gave us a whopping power bill, and at our own data center we never considered charging our customers for power.

I need to know what happens when a rack has capped its (lets say) 5A limit. I'm trying to calculate what exactly I can put into a rack and am considering that not all servers are going to be 100% load, as that would be bad performance anyway.
I guess it could do the following (but really don't know):
Cap performance of all servers
Cause system failures
Trip
The rack would have servers, a switch and perhaps a Remote Power Strip and Firewall. I don't know how they would be affected.

how much power the average hard drive would use? (ie a 1tb drive). I was looking on WDC's website and it said 7.5 watts peak durring writing and reading etc, so assuming thats at 110 voltage, would it be safe to assume that 12 drives @ 7.5 watts each would make a total of .81 amps? I am going off of the equation that Amps = Watts/Volts. So amps = 90/110
