IBM N series Release News 4 of 4
TGIF everyone! Our final installment of the IBM N series release news. I have updated you on the new generation PAM II Cards, SnapManger for Hyper V and today we will discus 10GB Ethernet/FCoE.
Consolidation is a great topic you will find lots of bloggers talking about and we mainly talk about either server consolidation with virtualization or storage consolidation with deduplication or cloning technologies. But now we have the technology to consolidate your network topology into larger pipes using 10GB ethernet.
This idea of moving from a slower network speed like 10 MB to 100MB or 100mb to 1GB has been all based on faster performance and building a bigger pipe to applications. Now that we can push 10GB there is a different idea behind the movement.
The movement comes on the heels of virtualization and ‘Doing more with less’ mentality. No longer are we looking for just faster speed, but we are looking at the cost that we can save by consolidating all of the 1GB links down into a single 10GB link.
I still think most people will recommend two 10GB links to help with high availability but why not use 1 10GB port as a primary and then a few 1GB links teamed (Vifed together) as a backup or failover. This will allow you to utilize the speed and performance with the hit of having to use two 10GB ports on your switch.
Just like the 1GB switches when they arrived on the data center scene, 10GB switches are still expensive. But if you look at history, the cost per port will start to come down after the ‘newness’ of it wears off and more and more people start adapting it as their standard.
IBM N series now supports the 10GB ethernet card with dual ports. This allows you to connect to two different switches or create a 20GB vif. The setup of the 10GB is the same as the 1 GB ehternet ports you have been using for years.
IBM N series is the first storage product (and only as of now) to support FCoE. The FCoE cards do come in two different flavors, fibre or copper ports. They are both setup as target cards and use a PCIe slot.

IBM today announced releases for the N series platform including the first IBM Storage product to offer FCoE support. The N series platform now includes
- Performance Accelerator Module – Second Generation
- SnapManager for Hyper-V 1.0
- Fiber Channel over Ethernet
- 10Gb Ethernet support
- EXN3000 SAS Expansion Disk
Over the next 4 days, I will be writing about these technologies and how they related to the IBM Smarter Planet initiative. With these technologies, you will be able to consolidate your data center infrastructure, use less power and cooling and make your solution more efficient.
With budgets getting tighter and CIOs asking to do more with less, companies are asking IBM to help them achieve this shift in the paradigm. The IT department is being not only to provide more services at a higher availability but some are asked to be revenue centers for the company.
The new Performance Accelerator Module II (aka PAMII) is an upgrade to its smaller brother the PAM I. The new flash memory card can be added to systems (both N6000 and N7000) in 256GB and 512 GB cards. Unlike Solid State Drives that accelerate data stored on the chip, the PAM II effectively extends the buffer cache for all data. By adding memory cache to the system, it reduces the total number of IOPS the disk subsystem has to perform across the entire dataset stored in the system.
Server virtualization has become a hot topic with many companies looking to consolidate the data center footprint. Now IBM is adding to the list of SnapManager software packages support for MS Hyper-V. SMHV is built on the SnapManger product line that cut it’s teeth on Exchange and Oracle many years ago. Much like those products, SMHV allows customers to backup and recover their virtual machines within the storage protection policies set by the backup administrator. Clients that use SMHV will find it easier to rapidly provision and clone their virtual machines and the ability to recover one virtual machine if needed.
Server virtualization has been a hot topic for a few years, and people have started looking at storage virtualization/consolidation within the last year. Something that was left out was the networking in the data center. The introduction of Fibre Channel over Ethernet (FCoE) and 10Gb Ethernet is allowing companies to save more money by consolidating older 1Gb lines into one or two lines. IBM N series is the first storage system to support FCoE hardware. We are very proud to have this honor and as customers look to IBM to provide an FCoE or a 10Gb product, we have a proven product that will help consolidate their network infrastructure.
The new announcement of the EXN3000 disk shelf is part of the IBM Smarter Planet goal. With a total capacity of 48TB raw disk in a 4 U footprint, we can reduce the number of watts consumed (per TB) more than 10% per shelf. The EXN3000 can use either SAS or SATA drives in 12 or 24 drive configurations. This equates to about 30% more dense storage than the EXN2000 or EXN4000 shelves. With a higher density storage footprint, less power and cooling is required for fewer spinning disks.
These technologies allow IBM customers to meet the tightening parameters that are changing the paradigm in IT. IBM is constantly building on the proven N series platform to enhance and simplify our customer’s environment while increasing efficiency with the world’s resources. Come back tomorrow for part 2 of 4 in the week long update on the IBM N series release.
Pick up any industry magazine or your favorite blog and you are sure to find them talking about how FCoE and FC over Convergence Enhanced Ethernet. We have been consolidating the servers into virtual machines and consolidating our storage at the same time, but now we can do the same with our networks.
We have 10 GB networks coming into the market place and they are gaining in popularity as network admins replace older technology with newer, just like when 1 GBPS switches came out to replace our 100 mbps one. But 10 GBPS actually goes beyond the speed of the network. We can now use fewer ports and fewer switches, which down the road leads to lower costs for power, cooling and rack space.
N series supports FCoE as well as iSCSI, NFS, CIFS all over the 10GBPS link. We also support VLAN tagging to help separate the different protocol workloads. Here is a great Redpaper that will explain FCoE and how it can help you.
