2.- Ericsson Expands GPON Solutions
Ericsson has made several enhancements to its GPON solutions. Its EDA 1500 platform now has a new
16-port GPON OLT board, enabling broadband services to more than 14,000 FTTH GPON subscribers in a
single EDA 1500 chassis.
Ericsson is also introducing an Integrated TDM Gateway (ITG) board to the EDA 1500, enabling a
converged platform for packet and TDM services across fixed enterprise and mobile applications. The ITG
terminates and aggregates E1 services across multiple GPON ports at the OLT for STM-1 connectivity to
existing TDM networks.
Also, Ericsson is further expanding its EDA portfolio with the T780G Optical Network Unit (ONU). This
GPON-fed modular ONU provides flexibility for operators delivering ADSL2+, VDSL2, POTS, E1 and
Ethernet services to both business and residential users. The T780G enables operators to support dense
areas with different service requirements without rewiring buildings. The ONU is part of Ericsson’s T-
series of optical terminals, which provides maximum flexibility to deploy deep fiber access networks.

4.- SAN performance best practices: More ways to avoid bottlenecks
George Crump, Contributor 02.15.2011
 What you'll learn in this tip: There are several ways you can fine-tune and improve your storage-area
network (SAN). This tip covers topics such as using ISLs and understanding HBA queue depth to help you
avoid storage bottlenecks.
In this tip, we take a closer look at how SAN performance and SAN efficiency improve with transparency,
testing and a better understanding of the impact your data storage has on the rest of your system. Check
out our earlier tip on how to improve your storage networks to find out how storage performance issues
are often linked to data storage networks with outdated information or that don't undergo regular
testing.
Tip 1. Understand how you're using ISLs
Inter-switch links (ISLs) are critical areas for tuning and, as a SAN grows, they become increasingly
important to performance. The art of fine-tuning an ISL is often an area where different vendors will
have conflicting opinions on what a good rule of thumb is for switch fan-in configurations and the number
fam’s teleco news (11ªEd-2-2011.)                                                                   2/7
of hops between switches. The reality is that the latency between switch connections compared to the
latency of mechanical hard drives is dramatically lower, even negligible; however, in high fan-in situations
or where there are a lot of hops (servers crossing multiple switches to access data), ISLs play an
important role.
 The top concern is to ensure that ISLs are configured at the correct bandwidth between the switches,
which seems to be a surprisingly common mistake. Beyond that, it's important to measure the traffic flow
between hosts and switches, and the ISL traffic between the switches themselves. Switch reporting tools
will provide much of this information but, a visual tool that measures switch intercommunication may be
preferable.
Based on the traffic measurements, a determination can be made to rebalance traffic flow by adjusting
which primary switch the server connects with, which will involve physical rewiring and potential server
downtime. Another option is to add ISLs, which increases bandwidth but consumes ports and, to some
extent, further adds to the complexity of the storage architecture.
Tip 2. Use NPIV for virtual machines
Server virtualization has changed just about everything when configuring SANs and one of the biggest
challenges is to identify which virtual machines are demanding the most from the infrastructure. Before
server virtualization, a single server had a single application and communicated to the SAN through a
single host bus adapter (HBA); now virtual hosts may have many servers trying to communicate with the
storage infrastructure all through the same HBA. It's critical to be able to identify the virtual machines
that need storage I/O performance the most so that they can be balanced across the hosts, instead of
consuming all the resources of a single host. N_Port ID Virtualization (NPIV) is a feature supported by
some HBAs that lets you assign each individual virtual machine a virtual World Wide Name (WWN) that
will stay associated with it, even through virtual machine migrations from host to host. With NPIV, you
can use your switches' statistics to identify the most active virtual machines from the point of view of
storage and allocate them appropriately across the hosts in the environment.
Tip 3. Know thy HBA queue depth
HBA queue depth is the number of pending storage I/Os that are sent to the data storage infrastructure.
When installing an HBA, most storage administrators simply use the default settings for the card, but the
default HBA queue depth setting is typically too high. This can cause storage ports to become congested,
leading to application performance issues. If queue depth is set too low, the ports and the SAN
infrastructure itself aren't used efficiently. When a storage system isn't loaded with enough pending I/Os,
it doesn't get the opportunity to use its cache; if essentially everything expires out of cache before it can
be accessed, the majority of accesses will then be coming from disk. Most HBAs set the default queue
depth between 32 to 256, but the optimal range is actually closer to 2 to 8. Most initiators can report on
the number of pending requests in their queues at any given time, which allows you to strike a balance
between too much and not enough queue depth.
Tip 4. Multipath verification
Multipath verification involves ensuring that I/O traffic has been distributed across redundant paths. In
many environments, our experts said they found multipathing isn't working at all or that the load isn't
balanced across the available paths. For example, if you have one path carrying 80% of its capacity and
the other path only 3%, it can affect availability if an HBA or its connection fails, or it can impact
application performance. The goal should be to ensure that traffic is balanced fairly evenly across all
available HBA ports and ISLs.
You can use switch reports for multipath verification. To do this, run a report with the port WWNs, the
port name and the MBps sorted by the port name combined with a filter for an attached device type
equal to "server." This is a quick way to identify which links have balanced multipaths, which ones are
currently acting as active/passive and which ones don't have an active redundant HBA.
Tip 5. Improve replication and backup performance
While some environments have critical concerns over the performance of a database application, almost
all of them need to decrease the amount of time it takes to perform backups or replication functions.
Both of these processes are challenged by rapidly growing data sets that need to be replicated across
relatively narrow bandwidth connections and ever-shrinking backup windows. They're also the most likely
fam’s teleco news (11ªEd-2-2011.)                                                                  3/7
processes to put a continuous load across multiple segments within the SAN infrastructure. The backup
server is the most likely candidate to receive data that has to hop across switches or zones to get to it.
All of the above tips apply doubly to backup performance. Also consider adding extra HBAs to the backup
server and have ports routed to specific switches within the environment to minimize ISL traffic.

6.- Network congestion set to worsen ITU calls for international broadband
commitment
Geneva, 11 February 2011 — Governments need to take urgent action now to support mobile
broadband growth. So says ITU Secretary-General Dr Hamadoun Touré, adding that accelerated fibre
roll-out and greater spectrum availability will be imperative if network bottlenecks are to be avoided.
     Smartphone users already consume on average five times more data capacity than users of ordinary
mobile phones[1]. With the number of smartphones set to rise from today’s global estimate of 500 million
handsets in use, to almost two billion by 2015, operators are already having to employ multi-pronged
strategies to keep up with demand – and not all are succeeding[2].
     “Mobile operators have been investing billions to upgrade and improve the capacity and performance
of their networks, but in some high-usage cities, such as San Francisco, New York and London, we are
still seeing users frustrated by chronic problems of network unavailability.
    “Robust National Broadband Plans that promote extra spectrum and the faster roll-out of the fiber
networks which are essential to mobile backhaul are vital to support the growing number of data-
intensive applications,” says Dr Touré. ITU analysis shows 98 countries have National Broadband Plans in
place, with this number set to increase over the next year.

13.- La beta de Windows 8 podría estar lista este año
Windows 8 será, según varias declaraciones de altos cargos de Microsoft, el sistema operativo más
sofisticado y evolucionado que hayamos visto nunca. Son palabras que abren las puertas a toda una
temporada de hype y especulaciones sobre el próximo sistema operativo de la empresa, y que podría
aparecer a modo de beta, después de verano.
Así lo avanzan en varios medios estadounidenses estos días, cuando hablan de una versión de Windows
8 para Tablets a principios de 2012 y la versión de Escritorio para finales de ese año, pues las pruebas y
fases del nuevo Windows van como la seda.
Recordemos que existirán dos versiones de Windows 8: Una para Tablet que funcionará con
procesadores ARM y la versión de Windows 8 para Escritorio, que vendría a sustituir al actual Windows 7,
el cual ha resultado ser todo un éxito en todos los aspectos.
Microsoft, por su parte, aún no ha hecho ningún anuncio oficial sobre la fecha de lanzamiento de
Windows 8, pero ya se han dejado ver hojas de ruta de fabricantes como Dell, quien incluso ha
desvelado el nombre en clave de dispositivos que llegarán con estos sistemas.

This tip covers topics such as using ISLs and understanding HBA queue depth to help you avoid storage bottlenecks. In this tip, we take a closer look at how SAN performance and SAN efficiency improve with transparency, testing and a better understanding of the impact your data storage has on the rest of your system. Check out our earlier tip on how to improve your storage networks to find out how storage performance issues are often linked to data storage networks with outdated information or that don't undergo regular testing. Tip 1. Understand how you're using ISLs Inter-switch links (ISLs) are critical areas for tuning and, as a SAN grows, they become increasingly important to performance. The art of fine-tuning an ISL is often an area where different vendors will have conflicting opinions on what a good rule of thumb is for switch fan-in configurations and the number
  • 2.
    fam’s teleco news(11ªEd-2-2011.) 2/7 of hops between switches. The reality is that the latency between switch connections compared to the latency of mechanical hard drives is dramatically lower, even negligible; however, in high fan-in situations or where there are a lot of hops (servers crossing multiple switches to access data), ISLs play an important role. The top concern is to ensure that ISLs are configured at the correct bandwidth between the switches, which seems to be a surprisingly common mistake. Beyond that, it's important to measure the traffic flow between hosts and switches, and the ISL traffic between the switches themselves. Switch reporting tools will provide much of this information but, a visual tool that measures switch intercommunication may be preferable. Based on the traffic measurements, a determination can be made to rebalance traffic flow by adjusting which primary switch the server connects with, which will involve physical rewiring and potential server downtime. Another option is to add ISLs, which increases bandwidth but consumes ports and, to some extent, further adds to the complexity of the storage architecture. Tip 2. Use NPIV for virtual machines Server virtualization has changed just about everything when configuring SANs and one of the biggest challenges is to identify which virtual machines are demanding the most from the infrastructure. Before server virtualization, a single server had a single application and communicated to the SAN through a single host bus adapter (HBA); now virtual hosts may have many servers trying to communicate with the storage infrastructure all through the same HBA. It's critical to be able to identify the virtual machines that need storage I/O performance the most so that they can be balanced across the hosts, instead of consuming all the resources of a single host. N_Port ID Virtualization (NPIV) is a feature supported by some HBAs that lets you assign each individual virtual machine a virtual World Wide Name (WWN) that will stay associated with it, even through virtual machine migrations from host to host. With NPIV, you can use your switches' statistics to identify the most active virtual machines from the point of view of storage and allocate them appropriately across the hosts in the environment. Tip 3. Know thy HBA queue depth HBA queue depth is the number of pending storage I/Os that are sent to the data storage infrastructure. When installing an HBA, most storage administrators simply use the default settings for the card, but the default HBA queue depth setting is typically too high. This can cause storage ports to become congested, leading to application performance issues. If queue depth is set too low, the ports and the SAN infrastructure itself aren't used efficiently. When a storage system isn't loaded with enough pending I/Os, it doesn't get the opportunity to use its cache; if essentially everything expires out of cache before it can be accessed, the majority of accesses will then be coming from disk. Most HBAs set the default queue depth between 32 to 256, but the optimal range is actually closer to 2 to 8. Most initiators can report on the number of pending requests in their queues at any given time, which allows you to strike a balance between too much and not enough queue depth. Tip 4. Multipath verification Multipath verification involves ensuring that I/O traffic has been distributed across redundant paths. In many environments, our experts said they found multipathing isn't working at all or that the load isn't balanced across the available paths. For example, if you have one path carrying 80% of its capacity and the other path only 3%, it can affect availability if an HBA or its connection fails, or it can impact application performance. The goal should be to ensure that traffic is balanced fairly evenly across all available HBA ports and ISLs. You can use switch reports for multipath verification. To do this, run a report with the port WWNs, the port name and the MBps sorted by the port name combined with a filter for an attached device type equal to "server." This is a quick way to identify which links have balanced multipaths, which ones are currently acting as active/passive and which ones don't have an active redundant HBA. Tip 5. Improve replication and backup performance While some environments have critical concerns over the performance of a database application, almost all of them need to decrease the amount of time it takes to perform backups or replication functions. Both of these processes are challenged by rapidly growing data sets that need to be replicated across relatively narrow bandwidth connections and ever-shrinking backup windows. They're also the most likely

The backup server is the most likely candidate to receive data that has to hop across switches or zones to get to it. All of the above tips apply doubly to backup performance. Also consider adding extra HBAs to the backup server and have ports routed to specific switches within the environment to minimize ISL traffic.

So says ITU Secretary-General Dr Hamadoun Touré, adding that accelerated fibre roll-out and greater spectrum availability will be imperative if network bottlenecks are to be avoided. Smartphone users already consume on average five times more data capacity than users of ordinary mobile phones[1]. With the number of smartphones set to rise from today’s global estimate of 500 million handsets in use, to almost two billion by 2015, operators are already having to employ multi-pronged strategies to keep up with demand – and not all are succeeding[2]. “Mobile operators have been investing billions to upgrade and improve the capacity and performance of their networks, but in some high-usage cities, such as San Francisco, New York and London, we are still seeing users frustrated by chronic problems of network unavailability. “Robust National Broadband Plans that promote extra spectrum and the faster roll-out of the fiber networks which are essential to mobile backhaul are vital to support the growing number of data- intensive applications,” says Dr Touré. ITU analysis shows 98 countries have National Broadband Plans in place, with this number set to increase over the next year. De: ITU Newsroom. Press Release.
