In Huawei optical transmission boards, SSN4 is equal to SSND00, and generally speaking, the same boards that display different product name have the same feature code, like SSN4SL6402 and SSND00SL6402. But When it comes to Huawei service board SSN4EGS411 and SSND00EGS412, some customers are misguided and some customers are asking that whether we delivered the wrong model of board to them, because In huawei BOQ, it is show as SSND00EGS412, here version code is ND00, feature code is 412; But in board front panel, it show as SSN4EGS411, here verison code is N4, but feature code is 411. Actually they are the same board.
To avoid this confuse, we suggest when ordering a EGS4 board, it better to comment with a optical specification behind like: (1000BASE-LX).
For example, when you are about to order a SSN4EGS411 board, you must select maybe you will choose configuration(slots and transmission range etc.) like as follow:
After you selected the configuration of this board, it will appear message box like this:
The product name shows as SSND00EGS412. But the product name that shows on the board is SSN4EGS411.
So when you buy this model of board later, you won‚Äôt be confused again.

StorPool is a software defined storage solution targeted at cloud application and infrastructure providers. The software runs on a cluster of commodity servers, aggregating the internal storage of those servers into a shared volume. The solution, for now, is only compatible with Linux based systems. For many online application or cloud providers this should not be an issue.
What makes the StorPool solution unique is the flexibility that permeates every aspect of the product. For example, many converged solutions require a lockstep addition of storage and compute. Each time you need to add capacity or processing power you have to buy both, in the form of another server, fully loaded. Most data centers, especially service providers, don‚Äôt scale that way. There are times when they need to scale just the compute aspects of their infrastructures and others where they simply need more storage.
StorPool customers can use a converged infrastructure when the data center needs both compute and storage resources. But, if one is needed more than the other, the organization can add dedicated storage nodes or dedicated clients (hosts with no storage). This ability to mix and match between converged, dedicated compute or dedicated storage is rare.

Cloud computing is growing rapidly. Businesses are moving to the cloud at an ever-increasing rate for many reasons. The agile ability to access applications from anywhere, anytime is a huge advantage for professionals. Dramatic cost savings are achieved by eliminating expensive hardware and software purchases, upkeep, and IT staff funding. Budgets are even improved by a reduction in overall power and utility bills when switching to the cloud. Many companies who have yet to make the switch are wondering if it will be worthwhile for them to consider.
Microsoft has recently announced that they will be ending support for the Server 2003 operating system. While this did not come as a shock to most, it most certainly served as a wake-up call. There are an estimated 2.6 million hot closets housing a Server 2003 operating system in businesses around the globe, and all will need to migrate over the next 8 months. The businesses will be faced with the decision: purchase brand new expensive hardware or look for an alternative solution at a much more affordable monthly rate. Cloud adoption is expected to climb dramatically during this time period as the hosted solution is more and more feasible, reliable, and secure.
As more and more businesses adopt cloud hosting services, studies and surveys are being conducted to determine satisfaction rates. Software as a Service (Saas) implementation is a huge decision for a company to make and therefore professionals are looking for the opinions of others who have already made the move. TechRepublic recently conducted a study of existing SaaS users, and the results were staggering. 91% of professionals surveyed report that their cloud computing solutions have either met or exceeded expectations.
These results are quite encouraging for businesses of all sizes who are considering making the move to the cloud. Software hosting is proving to be just as advertised and is benefiting businesses across the board. Many versions of business critical applications are available in the cloud. From SAP to your CRM of choice, QuickBooks hosting or Sage 50 hosting, all enterprise apps imaginable can be found in the cloud. This new data should help professionals make the decision to adopt a hosted software platform for their company's applications and data.

I have often faced questions like: what application hosting means and how it becomes handy to small and mid sized business? It is a common concept, but will be very difficult to understand if not given correct definitions. Let me try to explain it thoroughly.
Firstly, you should keep in your mind Application Hosting as ASP (Application Service Provider), SaaS (Software-as-a-Service), On-Demand software, or simply Outsourcing of your few IT needs. Though all of these keywords are correlated, they are not completely interchangeable, but the concept is the basically the same and fairly simple.
What Does Application Hosting Mean?
Application hosting is a software application distribution system where your application - CRM, tax and accounting application or other custom applications, are maintained and managed by a qualified service provider and made available to you, as a service over the Internet. So, it means that your applications are not going to reside on your in-house setup, it is going to be installed on the servers of hosting provider. The application can be easily accessed and shared by your company staffs, through a web browser. So, in the case of application hosting, the software hosting vendor is responsible for 24X7support, maintenance, installations, upgrades and security.
What is a standard hosting Provider?
The major characteristics of a standard application hosting provider is a company that has either developed the application and/or is certified by a software manufacturer. The major core benefit of having a standard hosting provider is that they have extensive working experience on related technologies and they know all the ins and outs. They know exactly how to make the application work and are able to support you with best available practices.
What are the Highlights of a standard hosting:
With an excellent hosting service, you should get the following:
Efficient backup practices to ensure data integrity
Instant setup and migration
Easy to use
Reduced cost with software, infrastructure and IT staff
24X7 technical support
Automatic and frequent upgrades
Ability to adopt new technologies
What are the major Benefits:
The major benefit of application hosting is that you have a common platform for your practices instead of having separate desktops for each individuals. This helps you to share a common data base to each, improving your team collaboration and overall productivity. In addition, you will get:
Sharing the information at a single platform
Enhanced company image and customer loyalty
Reduced costs and increased revenue
What kind of business entities look to host?
Since, application hosting is adopted a general practice, small and medium sized businesses are more aggressive to go ahead. Tax and Accounting firms have adopted application hosting as their core platform. QuickBooks hosting provider helps them to solve their purpose.
Microsoft Office still dominates market share of office suites. Businesses have often rejected free Office alternatives. However, whether this will continue is uncertain. With the cost of a price plan for Microsoft Office, the average home user or small business will welcome a free alternative. Fortunately, there are some truly excellent free alternatives available for Linux (and other operating systems). Not all of the office suites featured here are released under an open source license, but they are all free to download and use without charge.

Creep occurs on SD585 soldered balls of some cross-connect boards on Huawei transmission OptiX OSN 3500 equipment so these boards repeatedly reset, fail to work, and report BD_STATUS alarms.
There is a possibility that this problem occurs as a result of long-term exposure of the boards involved to high temperature.
1. Boards are reset repeatedly and fail to work.
2. NEs may report BD_STATUS alarms or COMMUN_FAIL alarms on cross-connect boards.System control boards may report BIOS_STATUS alarms on cross-connect boards.
The problem can be identified if the following two conditions are met:
1. The boards are manufactured in Feb 2010, Apr 2010, May 2010, Jul 2010, Aug 2010, or Mar 2011.
2. The cross-connect boards are repeatedly reset and fail to work. The board BOMs are found in the attached Board Delivery Information.
The SD585 chip radiator uses the thick spring, which applies high levels of stress to the chip. The soldered ball of the SD585 chip may deform and short-circuit as a result of long-term exposure to high temperature. Therefore, the board repeatedly reset and fail to work.
[Impact and Risk]
1. Services are not influenced because of the 1+1 protection scheme is configured on the cross-connect boards. When a cross-connect board is faulty, services are switched over to the other cross-connect board.
2. In extra situations, both cross-connect boards configured in the 1+1 protection scheme become faulty in a short time. As a result, the NE fails to work and services are interrupted.
[Measures and Solutions]
Replace the faulty cross-connect board.
Reference and buy new similar boards in Huawei network product distributors
Replace the faulty boards.
Material handling after replacement:
Return the spare parts for repair.
Replace the faulty boards.
SSN1SXCSA02 (03030KBM) boards are out of production, so replace SSN1SXCSA02 boards with SSN1SXCSA01 (03030DKF) when filling in an electric process application for board rectification in batches. The two kinds of boards can be mixedly inserted or completely replace each other. Active and standby boards of the same type are recommended.
Summary: The clock chips used on some TN55 of Huawei OSN product Optical OSN 8800 NE have design defects. As a result, the failure rate of the chips is 5% after they are in service for 2 years. In the case of a clock chip failure, services on these boards will be interrupted and cannot be restored even after you remove and reinsert or perform a cold reset on the boards.
The chip failure rate is 5% within 2 years. The chip failure rate is proportional to the service period but is irrelevant to application scenarios.
On the transmission faulty board, a Hard_Bad alarm is reported and cannot be cleared and services are interrupted.
1. Check the bar codes of the boards against the attachment. If the bar codes are included in the attachment which provided by the official website, you can determine that the boards are at risk of a clock chip failure.
2. If the previously described symptom occurs on a TN55 board, you can determine that the board is at risk of a clock chip failure.
You can also query the register using the following commands.
The clock chip has design defects. As a result, the TN55 boards have 5% failure rate within 2 years.
[Impact and Risk]
Optical OSN 8800: On a board with a defective clock chip, a Hard_Bad alarm is reported and services are interrupted. The services cannot be restored even after you remove and reinsert or perform a cold reset on the board. The chip failure rate is 5% within 2 years and is proportional to the service period.
[Measures and Solutions]
Replace the boards with a defective clock chip.
Replace the boards with a defective clock chip.
Material handling after replacement:
For markets outside China directly scrap the boards. For markets inside China, send the boards back to the Spare Parts Center for disposal.
The problem described in the pre-warning is triggered when the following four conditions are all met:
1.TPS is triggered or restored by the TPS protection group consisting of transmission boards in slot 12 and 13.
2. The NE type is OptiX OSN 1500B and its version is included in the ‚ÄúVersions Involved‚ÄĚ part.
3. The NE is configured with a TPS protection group consisting of processing boards in slots 12 and 13.
4. The NE is configured with a service processing board that needs work with an interface board in slot 7 or 8, such as SSR1PD1 and SSR2PD1. In addition, services are configured on the board.
The fault scenarios are as follows:
Scenario 1: Boards in slots 12 and 13 form a TPS protection group, and a board in slot 7 or 8 is not configured with TPS protection.
When TPS is triggered by the TPS protection group consisting of boards in slots 12 and 13, services on the board in slot 7 or 8 are interrupted and the T_ALOS alarm is reported. After the TPS is restored, the T_ALOS alarm is cleared and the services on the board are recovered.
Scenario 2: Boards in slots 12 and 13 form a TPS protection group, and a board in slot 7 or 8 is configured with the TPS protection group.
1. TPS is not triggered on the boards in slots 7 and 8:
When the TPS protection group consisting of boards in slots 12 and 13 triggers TPS, services on the boards in slot 7 and 8 are interrupted, and the boards in slots 7 and 8 report the T_ALOS alarm. When the TPS protection group consisting of boards in slots 12 and 13 is restored to the idle state, the T_ALOS alarm is cleared and the services on the boards in slots 7 and 8 are recovered.
2. If TPS is triggered on the board in slot 7 or 8:
When TPS protection group consisting of boards in slots 12 and 13 is restored to the idle state, services on the board in slot 7 or 8 are interrupted and the T_ALOS alarm is reported. When TPS on the board in slot 7 and 8 is restored, the services on the board are recovered and the T_ALOS alarm is cleared.
The problem described in the pre-warning is triggered when the following three conditions are all met:
1. The NE type is OptiX OSN 1500B and its version is included in the ‚ÄúVersions Involved‚ÄĚ part.
2. The NE is configured with TPS protection groups consisting of the service processing boards in slots 12 and 13. In addition, the NE is configured with a service processing board in slot 7 or 8 that needs to work with an interface board (such as SSR1PD1 and SSR2PD1).
3. Services on the boards in slots 7 and 8 are interrupted and the T_ALOS alarm is reported, which is triggered by TPS or TPS restoration in the TPS protection group consisting of boards in slots 12 and 13.
The software version has defects. Boards in slot 12 and 13 form a TPS protection group. When TPS is triggered or restored, relays on boards in slots 16 and 17 are switched no matter whether two interface boards are required to be configured on the service processing board in slot 13.
If two interface boards are required by the board in slot 13, the valid slots are slots 16 and 17.
If one interface board is required by the board in slot 13, the valid slot is slot 16.
When a service processing board with an interface board is required by the board in slot 7 or 8 (the interface board is in slot 15 or 17), services on the boards in slots 7 and 8 are affected due to TPS or TPS restoration in the TPS protection group consisting of the boards in slots 12 and 13.
[Impact and Risks]
TPS and TPS restoration will interrupt the services on boards in slots 7 and 8 which are configured with a TPS protection group consisting of boards in slots 12 and 13.
Measures and Solutions
It is recommended that you restore TPS for scenario 1 and trigger TPS to ensure that two TPS protection groups are in the idle state for scenario 2.
Currently, there are two methods available for working around the problem.
1. Do not configure TPS protection groups for boards in slots 12 and 13.
2. Configure TPS protection groups for boards in slots 12 and 13 on an OptiX OSN 1500B subrack but do not configure service processing boards or configure service processing boards that do not work with interface boards in slots 7 and 8.
