Technologies

We know. For some of you out there the last thing you want to read is a breakdown of our colocation technologies. For you, we streamline the process by talking about our solutions in general terms with dashes of specifics. However, for those of you out there who love tech, for the CTO’s and the IT pro’s among you, below is a quick but detailed listing of the essential AV5 tech.

Racks and power

Hardware:

  • Standard 45 unit racks allowing install up to 40 1U devices.
    • We utilize vertical 0U PDU’s

Power Config:

  • We recommend our customers utilize 208 volt configurations:
    • 208V is green energy friendly with higher density
    • 208V means avoiding upgrading power and PDU down the road
    • 208V allows for retention kit into each connection to avoid loose power cables

***AV5 supports 110 and 208 volt power configurations***

AV5 offers multiple configurations for optimal redundancy rates:

Low Level

  • Single PDU per rack providing no – very minute service degradation in case of rack failure
  • This config is normally used for cache servers distributed across M+N racks

Medium Level

  • Dual PDU per rack w/ single feed
  • Dual PDU per rack w/ single feed save money and the headaches caused by unreliable PDU’s and fuses

High Level

  • Dual primary & Redundant Feeds
  • Primary & Redundant are connected to distinct power systems
  • Each power system has its own internal structure
  • The main benefits of this set up are independent power sources ensuring uptime

***We recommend this setup for Racks w/ network Equipment Database Servers***

AV5 Supports the following PDU Models:

Non-metered & non-switched PDU’s

  • Cost effective
  • Cannot monitor power usage
  • Cannot reboot hardware remotely

Metered PDU

  • Allows for monitoring of power usage
  • Not a bank breaker, but also not the ground level expense

Metered Switched PDU’s

  • Can perform power cycle remotely
  • Only slightly more expensive than an AV5 Metered PDU

Servers

To more effectively choose what type of server you need, we have supplied a quick breakdown of the types of server. For example if you need a server for archiving a vast quantity of data, as the name suggests, a storage server is your best bet. Likewise, if you need a server to run maintenance tasks like log analysis, a system server is for you.

  1. Storage Server – Normally 4U servers containing up to 45 hard drives. Storage Servers can configured as both RAID 6 or RAID 10.
  2. Database Server – Normally 1U or 2U servers w/ 4- 8 hard drives. Hard drives are allocated to address system needs, database storage needs and local storage (data backup) needs. Additional hard drives are allocated as spares in case of failure.
  3. Application & Edge Servers – Normally these servers require powerful CPU for data processing needs. It should be noted, these servers require 10 gig network connections.
  4. Cache Servers – Normally used for hot content. Due to this Cache servers typically contain SSD with copious amounts of memory.
  5. System Servers – Normally used for log analyzing and other important maintenance tasks. These servers keep you on track.
Standalone servers

Outside of knowing the type of server you need, you also need to understand the type of chassis your server needs to be housed in. The following is a quick breakdown of the chassis AV5 offers:

Standalone

  • Chassis have their own power supply
  • Requires multiple network connections
  • Of all the chassis AV5 supports, the Standalone is the most flexible, upgradeable and price effective solution

***We recommend this solution for startups***

Twin

  • Midway solution between standalone and blade chassis
  • Allows for flexibility
  • Supplies effective power usage
  • Utilizes independent connections per server

Blade

  • Highest power ratio
  • Most effective management solution
  • Shares between all blade management and network modules
  • Embedded access switch is shared between blades and private VLAN’s are not supported. AV5 recommends utilizing an external switch to avoid aforementioned issues
  • Embedded management module is shared for all blades
  • Management users have access to all servers’ console
Load balancing structure

Network structure

AV5 offers our customers the following networking structure:

End of Row

  • One switch is installed in middle of row
  • All servers in row are connected to switch

Advantages of End of Row

  • This solution is cost effective, easier to manage, provides one hop between servers
  • All upgrades effect entire row

Top of Rack

  • Each rack has a switch with 24 – 48 ports utilizing 2 or more uplinks to the core network
  • Cables stay in rack (no long cables required)
  • Can split roles

Advantages of Top of Rack

  • Choose between cheaper and more expensive switches as needed
  • Highly flexible
  • High Performance
  • Very Reliable

Fabric Network

  • Each rack utilizes fabric switch (all switches are connected to main switch). All switches act as single device.
  • Supported by all major network vendors

Advantages of Fabric Network

  • Fewer Switches
  • More cost-effective than Top of the Rack design
  • Cables stay in rack
  • Flexible Rack architecture
  • Easy upgrade in future

Network Hardware

AV5 provides our customers with the best cost to performance ratio for all configurations. For example routers always face the Internet and access switches handle servers’ connectivity. Our network design consists of:

Core Routers

  • C.R.’s deliver your content to the Internet
  • C.R.’s sit in front of the entire network, they are aware of the entire global network and they deliver packets of data to your providers.

Core and Aggregation Switches

  • Contain high number of ports with lower price point
  • Each port collects traffic
  • Depending on network size, core and aggregation switches can be combined or split

Access Switches

  • Access switches are utilized in large installs to drive cost of installation and maintenance down
Access switches

Network security

We know. You need your data and your network to be secure. For that reason we provide you with industry leading firewall solutions:

Level 1 Security (Basic Access List)

  • Blocks unwanted traffic
  • Extremely cost effective
  • Must keep servers and applications current for Level 1 Security to work

Level 2 Security (Stateful Firewall)

  • Utilizes the newest gen of hardware firewalls
  • Maintains records of all connections passing through your firewall
  • Can determine whether packet of data is a new connection, part of an existing connection or an invalid packet

Level 3 Security (Advanced Deep Traffic Inspection)

  • Utilizes the newest gen of firewalls to inspect traffic and protocol aware appliances
  • Blocks viruses, spyware, modern malware
  • Detects and stops vulnerability exploits of applications and OS’s

Load balancing

AV5 understands with increased traffic you never want your solution to fail or report downtime. For that reason we provide the following load balancing solutions:

Cluster Load Balancing

  • Utilizes easy on the pocket hardware to build clusters of machines
  • In the case that one machine fails, all machines are not effected and services continue operating
  • Each machine maintains own power in case of single machine failure

Power Load Balancing

  • Consists of highly tested powerful servers with threshold limitations for traffic
  • Higher starting investment

Global redundancy

Like load balancing, Global Redundancy solutions aim to keep your business and up running even when the largest of disasters surface. Global redundancy provides:

  • Redundant data spanning multiple geographic locations
  • Low latency rates for retrieving, streaming and downloading content
  • Utilizes multiple datacenters across the world configured as active/passive or active/active
