A few years ago, I was managing a database system that had been upgraded from SQL Server 7.0 to SQL Server 2000. The upgrade went well and all issues were resolved except for one – we were experiencing very bad performance when attempting to read data from the primary replica of a mirrored server. This occurred even though the secondary replica had current copies of all the data and each transaction on the primary replica log was being queued up waiting for a disk write to occur. I asked our storage vendor if there might be an issue with blocking caused by some other process on our UNIX cluster as they suggested this as a possibility since they did not have visibility into any activity within SQL Server itself.
SOL server recovery:
- In my troubleshooting work dealing with these sorts of problems, I often like to begin using the Performance Monitor (Perfmon) tool. One of the reports I like to run right away is the “SQL:Buffer Manager – Page Life Expectancy (seconds)” report since it gives me an idea of what sort of overall performance impact might be occurring due to memory pressure and/or disk queuing.
- In this particular case, page life expectancy was constantly well below 20 seconds as our system was being pounded with full table scans from client applications for which we had not initially planned as part of normal business activity. This level of IO-intensive processing was causing a severe bottleneck on disk I/O that eventually caused a major storage subsystem failure. The drive array responded poorly to these sorts of loads and, as a result, the entire storage system eventually failed.
- In this case, we were fortunate that a complete set of system backups had been made on daily basis to an offsite location. In addition, all of our documentation was stored in a redundant location as well. Unfortunately, the SQL Server 2000 license key information was stored on the same server as the databases and as such it was unavailable after the failure as well as all data that was within these databases at the time they were lost due to system/storage/SAN failure.
- Fortunately for us – and you – I am going to explain how you can protect yourself from similar sorts of situations if your database servers are configured with shared disks and you use transactions and mirrored databases so your users experience an acceptable level of service even in the event of a shared storage component (e.g., disk, RAID controller, SAN) failure.
- The reason why this solution works is because it is leveraging existing functionality within SQL Server to implement production-level recovery procedures for protecting your data in the event of a system/storage/SAN failure without requiring you to purchase additional software or hardware components just for the purpose of recovering from such failures. I am not suggesting that these steps are 100% bulletproof, but if configured properly they will protect you from some very common types of failures that have been responsible for major downtime over the years.
When using mirroring with transaction logs on multiple disk volumes, there are four primary areas where things can go wrong:
- Loss of power/UPS to SAN/disks
- System failure (e.g., corrupted OS, hardware issues)
- Shared disk failure (RAID array, etc.)
- SAN controller failure
Most large database servers are configured with redundant power supplies and battery backup units to protect against loss of power which should provide sufficient time for a controlled shutdown that can be initiated by the system administrator via an automated process or manually if need be so this is usually not much of an issue unless you happen to have your server out in the middle of nowhere without utilities but even then there are plans available for these sorts of contingencies as well. But let’s say you do not have any kind of redundancy in place to power down the system, for whatever reason. In this case, you should still be able to initiate a controlled shutdown by using either the Windows “Shutdown” command or pressing and holding the power button until all activity on the server stops so it is not likely that data loss will occur in this scenario until there is another outage which allows the disks to spin up again without any kind of protection/containment.
The two main areas where I see people fail to account for system failures and storage component failures leading to data loss are:
- Lack of redundancy in power supplies and/or UPS units, and
- Not protecting your SQL Servers with RAID controller disk arrays as part of your standard server build process.

Why is launching an online business the greatest possible investment?
Some of the world’s most successful and well-known corporations began as little online businesses, as seen by their histories.
Among these successful businesses is Amazon, the world’s largest online retailer. Following that is Airbnb, the world’s largest lodging aggregator.
The majority of their work was done from either their homes, warehouses, or garages. Nonetheless, some individuals have achieved enormous success.
There are numerous such examples of online firms that have made it big.
High margins and low overheads
When you have an online business, you can often get rid of some of the huge costs that come with having a business in the real world.
You do not have to pay for expensive office space, retail space, or sign long-term leases. You also do not have to spend your money on stocking inventory.
Your financial risk can be reduced, and you will be able to maintain more consistent profits with less upfront investment if you enter a drop-shipping deal with the manufacturer or a manufacture-to-order arrangement.
Pro tip: How to find out someone’s email address?
As part of your marketing plan for your internet business, you will perform email marketing campaigns.
And as a first step, you will locate the email addresses necessary to construct the email list.
The best approach for this is to use email search tools if you do not know how to find out someone’s email address. I hope this information was useful.
Let us now return to the reasons for investing in online firms.
Offers a lot of room for growth
Scaling any business, whether brick-and-mortar or online, is difficult, but online businesses have advantages.
A brick-and-mortar retail store, for example, has a fixed audience, usually within a certain radius of the store.
This does not apply to an internet firm, which can market to a global audience.
You do not need your own website
There is no need to build your own eCommerce site like Amazon or eBay if you are starting an online store selling goods.
Instead, you may use Facebook Marketplace to create a free online store and market your business locally.
You can also build your own marketplace on sites like Etsy, Shopify, WooCommerce, and others if you want to reach clients throughout the county or internationally.
Earn money while you rest
You can make money even while sleeping with an online business. Yes, you read that correctly.
For this reason, your website or e-commerce platform is accessible to customers throughout the world at any time of day or night.
Doing business while working
Even if you are employed and have a regular, full-time job, you can start an online business as a side hustle and earn money.
This is a distinct benefit that only internet firms can provide. Because you do not have to be present in a store or office to run your business.
In recent years, a variety of fantastic widgets, apps, and plugins have become accessible for online businesses. This allows you to avoid wasting time on minor matters.
Sending email confirmations to clients, order tracking, forwarding orders to a third-party provider, tracking payments, and customer history are just a few of the activities that can be readily automated.
Online businesses are appealing because they avoid the usual roadblocks that most new businesses experience.
There are no startup charges, no rent or monthly bills, and you are not tied to a specific place.
As you can see, there is truly little reason you should not try to start an online business.
Things you need to know about Cloud PBX:
Cloud PBX is a private branch exchange or switchboard (PABX) that is delivered as a cloud-hosted service. Also called virtual IPBX, The main characteristic of virtual IPBX is that it is completely immaterial and allows a connection from anywhere via the Internet.
VoIP PBX: remote hosting:
A Hosted or Full IP PBX does not rely on the local server and resides entirely in the cloud, using only the VoIP protocol to connect and transmit calls. Often, this option is provided as a service, so you don’t have to purchase any hardware and there are few upfront costs.
How does it works?
The majority of providers only require you to purchase IP sets. As such, VoIP PBXs can be an ideal solution for small businesses or companies on a tight budget.
In most cases, telecom operators provide IPBX services hosted on the cloud and take responsibility for routing calls, maintenance, and activating options. Small businesses don’t always have the manpower, the budget, and the time to administer their own telephone systems, but this is a practical solution. On the other hand, they are dependent on the services of the operator, and often, the prices increase quickly according to the options chosen.
A Cloud PBX can also be a software-based, standalone, open-standard IP telephone switchboard that is simply hosted in the cloud instead of being installed on a local server. In this case, the company benefits from all the features included in the solution and is free to choose its telecom operator according to the rates charged. We offer a wide range of communication options such as voice mail, fax to mail, interactive voice server, and conferences.
Key Benefits of a Cloud PBX
Savings on acquisition and maintenance costs:
There is no need for a large investment in terms of the installation and deployment of the system. Maintenance costs are lower since they are often subcontracted by the host.
Eliminate the boundaries of your office – your employees can work from anywhere by connecting to the Cloud PBX. An ideal solution for people who are constantly on the move, such as home office enthusiasts or salespeople.
Improved brand image:
With a Cloud PBX-like phone system, an SME can easily deliver the image of a big business, thanks to advanced business telephony options.
Businesses can easily add or remove extensions and lines with a virtual phone system as they grow.
Easy to use:
Since the end-user has nothing to administer, this system is easier and more intuitive to use than a traditional PABX.
As opposed to traditional PBXs, when you work in the cloud, you can have unlimited extensions; as a result, no incoming calls are lost. A voicemail message will be left if there are no agents available.
By working on the cloud, you can have unlimited extensions. Add and remove extensions flexibly to adapt your standard to your business needs at any time.
Transfer and recording of calls:
With the Cloud PBX you can transfer calls between external extensions but also internal ones. In addition, you can access the recordings of incoming and outgoing calls to make a control and to be able to analyze and improve the service of the agents.
With this communication system, thanks to its cloud-based operation, you are able to add and adapt features as needed. In contrast to traditional PBXs, updates are simple and free.
Comparing a Cloud PBX to a traditional PBX can offer you multiple benefits, and any business can benefit from this type of technology.
