comment Do I need to have port 80 configured in LAMP for an HTTPS website?
@KoenvanderRijt ... and how is the browser supposed to get the http-packet containing the redirect to port 443, if the server doesn't listen on port 80 in the first place? ;-)

comment Accessing MySQL Remotely - Best Practices
Not sure, what you exactly mean with intrusion - if you want to access MySQL over the network (whether via RDP, SSH or the MySQL protocol directly) you have to allow some kind of connection. In my opinion the most secure way is using SSH with key based authentification.

comment Accessing MySQL Remotely - Best Practices
@114 I would really use cygwin with the OpenSSH deamon for the server side setup. There are a lot of tutorials. This for example looks like a pretty complete/decent one. On the client side, almost any tool has native support for SSH tunneling, examples are the already mentioned MySQL Workbench (free) HeidiSQL (free) or SQLyog (commercial) or MySQL for Excel (free, using Putty for the SSH tunnel).

comment Will a H310 Mini or a H200 support Samsung SSDs (840/850 Pros)?
@AndrewWhite The H310 only supports 16 drives per volume - but yes, from a theoretical standpoint your math would be right. It's hard to generalize. This all depends on your custom workload and I doubt you would reach such high queue depths. Regarding bottlenecks, in general the H200/H310 is an entry level-controller - for example it also suffers from poor write-performance with any parity-based RAID volumes and with synchronous I/O (just google "h310 performance issues"). The queue depth is only one factor in I/O performance.

comment How can an SSL certificate work for some clients only?
@FabienSnauwaert Yeah, if you scroll down to "Handshake Simulation", the SSLLabs test will try to simulate various OS/Browser version combinations. The browser doesn't handle SSL connections totally on it own, but partly relies on the implementation of the OS. So definitely the OS version makes a difference.

comment RAID 10 - many slow disks vs fewer fast disks
@Noctalin while it's OpenSource, commercial support is provided by Citrix (which is a billion dollar company) and it runs some of the biggest clusters in the world. So. Yeah. Pretty reliable according to my standards. Choosing between the big three (ESXi, XenServer, Hyper-V) is a matter of personal choice I would say. ;)

comment RAID 10 - many slow disks vs fewer fast disks
@Noctalin Yeah, looks like those are your options. Maybe you also want to consider to switch to Hyper-V or Xen. They both offer similiar features while supporting soft RAID. ESXi always sucks for hardware compatility anyway (I think they want to enforce use of certified hardware only) ...

comment RAID 10 - many slow disks vs fewer fast disks
@Noctalin That's what I meant in my original post with ESXi natively only supports hardware RAID - if you create a RAID through your motherboard, ESXi simply won't see it/ won't be able to use it. It lacks the drivers. Generally almost all onboard S-ATA controllers are "unsupported"/ not on the ESXi HCL. They just happen to fortunately work through the generic ahci driver - but only in AHCI and not in RAID mode.

comment Root-causing vastly different performance on iozone O_SYNC benchmark for two HDD manufacturers
@Vimal I edited my answer and tried to expand a little bit on your question, if that doesn't suffice (I'm not totally sure I understand correctly), you may really want to post it as a new question. ;-)
