Hardware
- Dell R410 Server
- Dual Intel quad-core server with Intel 5600 Series Westmere processors
- 256KB L2 cache per core
- 12MB L3 Cache per CPU
- 1066Mhz front side bus
- Up to 24GB DDR2-FBDIMM 667Mhz memory
- 15K SAS Hard Drives in RAID 10 Configuration
- 15,000RPM Spindle speed
- Battery-backed hardware SAS Raid controller with 256MB write Cache
15K SAS Hard Drives in RAID 10 configuration provides zero read/write contention between drives and tagged command queuing for highest performance over traditional SCSI or SATA drives. RAID 10 for fastest read/write performance. RAID 10 is a stripe of mirrors offering full data redundancy without the need of costly parity calculation.
15,000RPM Spindle speed provides fastest read/write access and data transfer at 3.0Gbit/s per drive to the SAS controller.
MySQL Tuning for WordPress
- MySQL runs on a 15K SAS disk RAID 10 filesystem
- MySQL my.cnf variable tuning specifically for WordPress
Security Enhancements
- The OBP server has all unnecessary services disabled both for performance and security.
- Nightly YUM updates keep all libraries and packages up to date with latest available versions.
- The system kernel is kept up to date utilizing Ksplice live kernel updates. No reboots required.
- Custom built latest stable PHP 5 version is installed and upgraded as needed.
- WordPress runs in a secure CHROOT environment for an additional layer of security
- All WordPress servers come with APF (Advanced Policy Firewall) configured with optimal rulesets for WordPress.
- SSH Access is limited by ip access restrictions.
Operating System-level Tuning
- System Integrity Monitor (SIM) watches all critical system services.
- All Kernel variables have been optimized for highest system performance.
- The system disk scheduler has been adjusted for best performance with the hardware raid controller.
- System networking variables are optimized for throughput and set to ignore source-routed, spoofed, and redirected packets.
Web Server Optimization for WordPress
- PHP open_basedir is disabled for as it can hurt PHP performance.
- PHP caching is handled by eAccelerator PHP accelerator, optimizer, and dynamic content cache on WP-OBP-100, WP-OBP-200, and WP-OBP-300 plans. WP-OBP-400 Plans and OBP clusters utilize APC for PHP caching.
- PHP Realpath cache settings are increased
- Apache KeepAlives are enabled and tuned for efficiency.
- Gzip output compression is enabled
- A secure Memcached instance in setup to be used with W3 Total Cache. This allows the WP cache to utilize ram for caching instead of the filesystem.
Network Optimization
- Fully burstable 1000BaseT uplink
- BGP Version 3 redundant network serviced through 4 separate carriers
- Our network consists of enterprise level Cisco Catalyst 6500 series equipment for both our core and distribution
Backup Strategy
- Redundant secure backup systems
- Continuous data protection. We backup your site files using R1soft's CDP Backup software. Backup copies are kept in two locations, one on your server and the second on a remote backup server
- MySQL database data backed up nightly for all plans
- Backed-up data is retained for up to thirty days
