The ADAPEI de la Meuse chooses All-Flash for its IT system

Faced with the increasing current and future performance needs of its ERP, the ADAPEI de la Meuse chose the HPE Nimble Storage All-Flash Array. It decreases data access time by a factor of 100 and is supervised for proactive maintenance through HPE InfoSight.


Increasing performance needs of the information system
The ADAPEI de la Meuse is an association created by the friends and parents of disabled children. From the age of 3 to 5 years, the children enter special education and rehabilitation services centers, where they receive schooling and then, later, vocational training according to their abilities. On reaching adulthood, they enter an ESAT, a work integration social enterprise, where they can participate in various activities such as horticulture, market gardening, industry, etc. The ADAPEI has signed agreements with many companies in the Meuse department, where these young disabled persons complete their activities perfectly. Today, the organization employs 800 people, soon to increase to 1,000, and uses ERP for its many operating needs, such as human resources or the individual computerized medical files of these young patients. "In addition, in our region, our association represents 23 sites, with various personnel who do not know each other but who need to exchange data regularly. Therefore, in 2014, we decided to unite everyone through IT, with a data center deployed at our head office in Vassincourt. We are also aware that we have more and more sensitive data which needs to comply with GDPR," says J�r�me Borras, Information System Manager, ADAPEI de la Meuse.
Linking several remote sites to a business ERP increased performance needs enormously, because, although installed in the data center, it is accessible through remote offices. For example, it enables 800 pay slips to be edited every month, and ensures the operation of several office software tools. "Initially, we used a 4 TB storage array with mechanical hard drives, from a rival brand of HPE. Everything was fine until we reached 400 users after two to three years. My diagnosis was that this was a problem of latency on the storage, that slowed remote sessions as simultaneous accesses to the data increased," says J�r�me Borras. It is true that the ADAPEI sites were connected to the ERP via several different communications technologies such as ADSL, MPLS, etc. Optical fiber had not been installed everywhere yet, which prevented implementation of a cloud-based system. It was essential that the links with the least bandwidth receive the benefit of a reliable flow at the data center level to avoid serial slowdowns on the users' interfaces. It must be pointed out that the ADAPEI de la Meuse is an establishment that operates night and day. Its ERP must therefore be accessible continuously, in particular, the DIUs (Users' Individual Medical Files) where all the information and actions linked to a patient are entered and stored.


Performance increased by a factor of 100
In 2017, J�r�me Borras, who alone ensures the functioning of the information system, was searching for a proactive solution. The goal was to make a number of tasks automatic, so as not to be confronted with a breakdown that blocked everything. By chance, he met with teams from HPE Nimble Storage at an IT conference. "HPE offered to come to our data center to do a POC free of charge. After jointly estimating the volume required, they connected their full SSD array to our information system. The first tests showed that the storage access times fell on average to 0.2 milliseconds, when our previous array did not go below 15 to 20 milliseconds. In terms of inputs-outputs, we stagnated at 400 inputs/outputs per second with the current solution, whereas the Nimble AF1000 All-Flash array from HPE went up to 35,000 I/O per second," he emphasized.
