Would I be right in thinking that Iceland is quite vunerable to seismic activity and that would mean it is not a great place over a datacentre because it could be wiped out by a natural disaster?
Most of seismic activity is Volcanic in origin. obviously there are certain places in Iceland you wouldn't want to build a data-center. However if you are building a proper redudant setup then you would have a DR/HA (disaster recovery/high availability) setup where all the data in Datacentre1 (DC1) is replicated to DC2. What's important there is low latency connection between DC's. I would imagine using this connection you could probably get 25ms between Iceland and Connacht. a 100Gbit/s connection between the two for data replication/clustering would enable 12.5GBytes/s of data transfer. In event of natural disaster in DC1 (iceland), DC2 transperantely takes over without the loss of any critical data.
Clustering is one of the reason that most of the banks in the World Trade Center didn't suffer any downtime. all there servers on site were configured with clustering/failover to remote sites (New Jersey etc.)
A good example of course at the moment is in the whole "Cloud" space, at least two major providers recently suffered a power outage in West Dublin, in both cases they were able to migrate customer's "machines" (Virtual machines in reality) to seperate DC's on continent.
This cable is configured to carry 100 x 100Gbit/s waves per cable pair. Total of 6 cable pairs, so that's add up to 600 x 100Gbit/s waves. Of course Eircom for example use 10Gb/s for it connections between say Galway/Cork and Dublin. Total bandwidth is 60Tbits/s
Looks like the ducting in NRA roads will finally get used. Here's a map from "Project Joshua" announced by PiPiper. It's obviously gonna provide the redudant link across Ireland for Emearld Networks.
The big thing here if you ask me is alot of new ducting going into West of Ireland. Galway to Donegal, as well as North Mayo through to Sligo. This makes the whole area considerably more viable for anything that requires very high levels of Data. It also connects in with Hibernian Atlantic via their "Project Kelvin" (landing station in Derry).
There is ducting in the Motorway to at least Kilcock.
Rollout of Ireland’s dark fibre network to generate 277 new jobs
I heard about one bank who's backup data center was just across the street in the third building that also collapsed, whoops!!!
Also many of the banks had backup office space and trading floors rented nearby. But they were all renting from the same facility and then there wasn't enough space for all of them, as the facility was knowingly "oversold" and they never expected that they would all need to use the backup facility at the same time!!
Only by the banks working together and helping each out, sharing facilities, etc. was a major financial disaster averted.
This lead to a major industry rethink of disaster planning and making backup data centers more geographically spread out.
To compliment the maps above ("Project Joshua", NRA map, EST Telecoms) here's a map of BT fibre assets in Ireland. I hadn't seen this till I went looking for it today.
Alot of BT fibre route is along CIÉ owned rail track. Been part of the deal done between CIÉ and Esat Telecom back in the day.
If the gov get off their arse and sort out LTE licensing for Mobile phone space you will see a big demand for fibre to base-stations.
I would point out that BT are a managed services operator rather than a dark fibre provider.
Also the redundancy shown into Ballina via Sligo and the 20Km Delivery circles both appear to be 'optimistic' claims.
The current pricing may not entirely viable either although one would expect the arrival of a new entrant to improve matters.
Hi, a bit off the subject but does anyone how I can connect 2 office buildings in Dublin via fibre. Is there a company I can use that can organise this by using exsisting ducts as the distance is just over 3 miles.
Well whereabouts in Dublin are these office buildings? City center or periperhal? The first thing I would do is look for quotes off the relevant fibre providers out there. eg:
- Smart Telecom
If both buildings are already connected by fibre to a fibre backbone *, then it would be much cheaper to just rent capacity with a Service Level Agreement on the existing fibre and create a Virtual Private Network between the two buildings.
The normal players dubhthach mentioned can help you with this.
* And even if they are not, it is probably cheaper to have them connected, then it would be to lay fibre between them directly.
Well the first thing to understand is that Eircoms new fibre strategy will still mostly involve DSL.
It will mostly be VDSL2 in local cabinets feed by fibre.
Some of the dal modems Eircom have been installing in recent years are probably upgradable to VDSL2 and will continue to be used in the new investment.
Those that aren't, could be redeployed. Adsl2 dslams moved to exchanges with older adsl dslams and older adsl dslams can be moved to exchanges with no adsl.
So this new fibre investment won't necessarily invalidate previous investments. Either way they desperately need to make this investment. The alternative is to continue losing customers to UPC at a vicious rate.
Two of the 15 "missing" DSL exchanges from the old plan would save me INCREDIBLE amounts of hassle in work (customers in those towns reliant on shonky wireless products or similar where proper VPNs are required) so if there is redeployment of DSL1/DSLMax DSLAMS I'd be delighted.
I'm, however, likely to be stuck on DSL1 forever - Maynooth is split in to two exchanges, "Maynooth Moneycooley" that's got DSL2 for quite some time and was one of the first for DSLMax (NGB) and "Maynooth Business Campus" that has DSL1, not even DSLMax.
Two housing estates are wired to the latter due to having had historically very poor lines to Moneycooley and I live in one, my parents live in the other.... and neither has UPC either which the rest of the town does!
I deleted the last post which had been cross-posted in UPC forum. Customer relations with a telco isn't really relevant to actual infrastructure forum anyways.
I'll also post elsewhere... Deleting the post does not seem to work on the touch site?
