Answer For modern drives (SAS / SATA), HP's "Hot swap" and "Non-hot swap" drive designations refer to the type of drive caddy (** and controller) used, rather than anything particular about the drive. All SATA and SAS drives are electrically hotswappable. (For SCSI and IDE disks, there was a real difference - only SCA SCSI disks were hotswappable, nothing else was) So, if you have the correct disk caddies already, you can physic...

Poke around on the netcraft.com site and you'll not be skeptical anymore. Here is a great resource about what's coming up in the Web Farm Framework for IIS 7 that has to do with scaling, load balancing, and provisioning.

Short version : rm -rf mydir , with mydir (recursively) containing 2.5 million files, takes about 12 hours on a mostly idle machine. More information : Most of the files being deleted are hard links to files in other directories (the directory being deleted is actually the oldest backup made by rsnapshot ; the rm command is actually given by rsnapshot ). So it's mostly directory entries being deleted - the file content itself isn't much; it's in the order of some tens of GB. I'm far from certain that btrfs is the culprit. I recall backup was also very slow before I started to use btrfs , but I'm not certain that the slowness was in the deletion. The machine is an Intel Core i5 2.67 GHz with 4 GB RAM. It has two SATA disks: one has the OS and some other stuff, and the backup disk is a 1 TB WDC ...

So the wise thing to do with something like a G7 server in 2014 is: Keep the server's warranty active. Once you hit the 3 year factory warranty, you can buy additional 1 or 2-year Care ...

itemprop="text"> I'm trying to setup an IPv6 web-server on CentOS 7.2 with NGINX. I have tested my IPv6 connectivity outgoing and incoming - everything works. My IP, AAAA records, etc as fine as well. Essentially everything is OK until I enable FirewallD. I have it set up to default to the drop zone with eth0 interface. I have enabled dhcpv6-client, http, https and ssh (ssh is on a custom port). When the firewall is enabled no IPv6 traffic can leave or enter the machine. Traceroute6 to anything (even the gateway) only goes to localhost. If I disable the firewall, it's all good. I have no idea why this is happening. I couldn't find anything online in order to make FirewallD apply the same IPv4 config to the IPv6 traffic. I personally thought, it would do that automatically, as all of its commands are IP protocol agnostic...

After following the logic through the rules that firewalld puts in I found that the drop zone...

A website I've been helping out with is hosted on a web host (not my choice) that only provide FTP to files (no shell access) and the database can only be accessed from the host itself or phpMyAdmin. The website is running on Apache with PHP version 5.3.13. Since bad and unforeseen things happen to websites from time to time, I'd like to have a backup of the website. I of course have most of the infrastructure locally already (database schemas and website source files), but if the website got hacked or something else bad happened, I would be left with a blank website. So I of course need to back up all user uploaded media and all data in the database. Problem is I'm really unsure how to do this in a good way when all I have is FTP access and no direct access to the database. Any advice on how to get a decent automatic backup of this...

itemprop="text"> I have a client with an Access Database that has been experiencing slow queries in the past few days. Here is some background first. it is currently running on Windows Server 2008 the mdb file is on the server and there are some local installed front end parts on the workstations. we run over a gigabit ethernet and gigabit network switches this server is used for basic file sharing too and those other services DO NOT seem to run slow or exhibit any issues. this was working fine but has begun having slower queries or response times when you connect back to the database for queries. we have not changed anything on the server or done any updates to either the server or the database front end installation. we have always used a mapped drive letter to access it, both on the old server and on this...

I'm building a simple ZFS file server for the small business I work for. The server is a Dell Poweredge 840, with 1GB RAM. The OS (OpenSolaris 2009.06) is installed on one SATA drive, and there are three other SATA drives installed for storage: 1x1TB, 1x1.5TB, and 1x2TB. When I add the three drives to one raidz zpool, throughput isn't very good: #zpool create -m /export/pool pool raidz c7d1 c8d0 c8d1 #zfs create pool/fs #time dd if=/dev/zero of=/export/pool/fs/zerofile bs=1048576 count=1024 1024+0 records in 1024+0 records out real 0m12.539s user 0m0.002s sys 0m0.435s That's about 81.6 MB/s. That's not horrendous, but I tried creating a pool consisting of just one of those drives: #zpool create -m /export/disk-c7d1 disk-c7d1 c7d1 #zfs create disk-c7d1/fs #time dd if=/dev/zero of=/export/disk-c7d1/fs/zerof...
