This provides direct management access without the need for IP connectivity, and can be used for the initial setup of this system and also for out of band management access. The console port is used for management traffic only. The port numbering is labelled on the back of the controller, so you can see for example the first two 10Gb Ethernet ports are 'e0a' and 'e0b'. They all have exactly the same ports in the back. The higher the model number the more powerful the controller, the more load it can handle and the more disk drives it can accommodate.
Then four UTA ports, 'e0e' to 'e0h' if they're configured as Ethernet ports, or '0e' to '0h' if they're configured as Fibre Channel ports:. With the NetApp port naming convention, Ethernet ports start with an 'e' for example 'e0g', Fiber Channel ports are not prefixed with a letter, for example '0g'. The FAS can either be purchased as a single chassis enclosure, where it looks physically identical to a FAS, or in dual enclosures where it looks physically identical to a FAS This is what the single chassis enclosure model looks like:.
When deployed in a single enclosure, the FAS is different than the FAS in that it has more memory so it can handle more load. The other option for the FAS is to purchase it in two different chassis enclosures. With the two chassis option, the controller fits in the top slot, and underneath there is an IO expansion module which provides eight additional expansion slots.
You will get two of the enclosures pictured above. There are eight expansion slots in the IO expansion modules, so that gives you an additional 16 expansion slots across the two chassis. Also note that the M.
Alternatively, an M. For more about fast storage, be sure to check out our SSD buying guide. Note that some PCIe slots may be wired for fewer lanes than the slot length suggests, or have some lanes disabled depending on what other slots or fast drives are installed.
In the image above, if you install a gaming graphics card the vast majority of which are at least two slots tall in either of the two x16 slots, the shorter x1 slots below them will be blocked. Lastly, a note about metal-wrapped PCIe slots: These are increasingly common in high-end and even mainstream boards. The idea is that they provide more support for large graphics cards, to keep the plastic slot from cracking or outright breaking under the weight of heavy cards.
But unless you are going to ship your system, or plan to cart it to LAN parties and you have a very big, heavy card, metal slots are more for show than a necessity. Some low-end chipsets are also limited to two slots, because only one DIMM per channel is supported. That said, for most mainstream tasks including gaming 16GB is good enough and 32GB is ample. Likewise, the USB 3.
ATX is the de facto standard, and offers the most space for features and expansion. And a tiny Mini-STX form factor 5. Another key board consideration is, of course, what CPU you need it to support. For all you need to know about choosing a processor, you can head to our CPU buying guide. But chipsets can be incredibly complex, enough so that a story could be written about each one. For feature details and comparisons of those and other current chipsets, you can check the charts below.
And the newer H chipset features up to four faster USB 3. A dry riser system is designed to be charged with water by the fire brigade. A wet riser system is kept full of water via water tanks and pumps. Dry riser: a system of valves and pipe work which enables the fire service to pump water onto upper floors of a building. Wet riser: a system of valves and pipe work which is kept permanently charged with water, generally utilising pumps and tanks.
The wet riser system is similar in design to dry risers and can usually be found in buildings over 50m tall. Unlike the dry riser system, it is kept constantly charged with water, in order that it can provide the same level of protection against a fire in the upper reaches of taller properties as on the lower floors. Dry risers themselves should be within fire-fighting shafts, and where necessary in protected escape stairs. Dry riser outlets, or landing valves, may be located in protected lobbies, stairs or enclosures where these are available.
A wet riser, known as a downcomer, is a water pipe built into the building which is permanently charged with water, often from a tank in the roof or on a water supply connected to a fire pump. Skip to content Lifehacks. January 19, Joe Ford.
