This is An IBM Redbooks publication
This IBM® Redbooks® publication gives a broad understanding of storage clouds and the initial functionality that was introduced for mainframes to have Transparent Cloud Tiering.
IBM DFSMS and the IBM DS8880 added functionality to provide elements of serverless data movement, and for IBM z/OS® to communicate with a storage cloud. They introduced the following key areas:
- A gateway in the DS8880, which allows the movement of data to and from Object Storage be using a network connection.
- DFSMShsm enhancements to support Migrate and Recall functions to and from the Object Storage. Other commands were enhanced to monitor and report on the new functionality.
- DFSMShsm uses the Web Enablement toolkit for z/OS to create and access the metadata for specific clouds, containers, and objects.
- DFSMSdss enhancements to provide some basic backup and restore functions to and from the cloud.
This IBM Redbooks publication is dived into the following parts:
- Part 1 provides you with an introduction to clouds. You might be new to clouds or have a confused view of cloud terminology. If so, Part 1 is helpful in providing you with the basic knowledge you need.
- Part 2 shows you how we set up the Transparent Cloud Tiering in a controlled laboratory and how the new functions work. We provide points to consider to help you set up your storage cloud and integrate it into your operational environment."

Points to consider buying a good mattress and assuring Improved Sleep
Spending in bed around a third of every day is common, regardless of whether this time is spent slumbering blissfully or turning and tossing. All these depend on the mattress. There is no doubt that a mattress has a great impact on the sleep of a person. Mattresses affects sleep also relates to the network of capillaries, the fine blood vessels running beneath your skin.
Lying on your body for a period of time means the weight reduces the blood flow to those blood vessels, thereby depriving the nutrients and oxygen to the skin. This causes pain sensors and nerve cells sending your brain a message to roll over. Rolling over assures good blood flow, but it also disturbs your good sleep.
Ideally, a good mattress improves your sleep and can be more productive at work. This is because a good mattress reduces on your body the pressure points and gives a better night's sleep. However, note that the ideal mattress varies with each person. The productivity level depends on our activity and inactivity. People failing to acquire good sleep at night cannot recharge their brain and body fully. The performance will surely deteriorate.
There is a need to change the mattresses after a span of 5 to 7 years. Likewise, while investing for good bedding significantly, there is a need to ensure there is the original bounce even after 7 or 10 years, so that it proves to be a good mattress improving your sleep and you can be more productive at work. Alongside good pillows are equally important.
Things to consider
- Buy mattresses that are not too soft or too firm.
- Mattresses too firm may cause misalignment and too soft sinks your body causing bad posture while sleeping, leading to pain.
- Consider adjustable beds and if possible take mattress on a test drive
- Check and confirm about trial periods or comfort guarantees before buying
- Without fail, check the warranty period.
A good mattress improves your sleep and can be more productive at work is true, but as such there is no definition making a mattress firm or soft. This is because a person who is 250-pound may say the mattress is soft, while the same mattress for a person with 125- pound may find it firm.
Which Mattress Is Right?
Finding a right mattress is not like looking for some top-tech brand. In fact, even an expensive mattress may not be as per your expectation. A high price tag alone does not determine the mattress. So, avoid concentrating on brand name or price, and think that you expect in a mattress that is really very personal. The choices vary, some prefer softer, while some firmer.
Of course, there is no scientific evidence proving the mattress type that can ensure you sleep better. Thus, consider buying a medium-firm mattress with a softer pillow that will offer the required cushioning and balance of support.
An adjustable bed also is a good buy if you prefer sleeping positioning your head raised. Such beds allow adjusting your hips and knees to a 90-degree angle and relieve sore joints.
