A Recap of the Storage Meet the Developers Session from IBM Edge
What is a Storage Free for All? That was the question many IBM Edge Attendees stopped by the Social Media Lounge Thursday in the late afternoon to ask me. On Twitter some were speculating that it would be a “storage throwdown.” I had to look at the conference agenda to see that there reallly was such a session on the agenda. So what’s a Storage Free for All? It turned out to be an opportunity for IBM Edge attendees to bring their questions about IBM products forward to a team of IBM developers and exports. The Q&
IBM offers a Change and Configuration Management Data Base (CCMDB) for this purpose with appropriate collectors from z/OS and distributed systems, but hasn’t sold well.
Both IBM Systems Director and IBM Tivoli Storage Productivity Center (TPC) offer RESTful APIs. IBM Systems Director can manage z/VM and Linux on System z, as well as Power Systems and x86 based distributed systems. Since October 2008, IBM’s Project Zero introduced RESTful interfaces to PHP and Groovy software running on WebSphere sMash environments. We have not heard much about this since 2008.
TPC 5.1 has support for this, and we expect to retrofit to feature with TPC 4.2.2 Fixpack 2.
Submit an IBM Request for Enhancement [ RFE ] for this. We have TPC for Replication on z/OS, as well as the distributed systems version that runs on Windows, Linux and AIX.
Yes, submit the requirements for our review.
The PureSystems family of expert-integrated systems is based on a new chassis that has a front part, a midplane, and a back-part. All IBM System Storage products that support x86 and Power Systems can work with PureSystems. However, IBM does not yet offer storage that fits in the front part of the PureFlex chassis, but the Statement of Direction indicates that we intend to offer that option. Until then, the IBM Storwize V7000 is the storage of choice that can be put into the PureSystems rack, but outside the individual chasses.
IBM’s new pilot program, the SmartCloud Virtual Storage Center, to bring these all together. In general, we have design teams of system architects that determine which features go in which products, and prioritize accordingly.
First, I want to emphasize that Big Data is more than just MapReduce workloads. IBM offers Streams and BigInsights software to handle text, as well as Business Intelligence and Data Warehouse solutions for structured data. IBM’s General Parallel File System (GPFS) has a Shar ed-N othi ng-C lust er (SNC) mode with Hadoop interfaces that runs twice as fast as Hadoop’s native HDFS file system. The storage products we recommend for Big Data are the SONAS and the DCS3700 disk systems, as both are optimized for the sequential workloads Big Data represents.
The advantage of storage hypervisors like SVC is that we can separate the multi-pathing driver from the back-end managed disk systems. You only need the SDDPCM to support the SVC, not the back-end devices. For the most part, SVC has not dropped support for any level of previously supported OS or multi-pathing software.
Yes, we had several requests like this, which is why we now recommend using Volume Mirorring to perform migrations. In fact the GUI wizard uses Volume Mirroring by default when migrations are performed. As for throttling, IBM has implemented “ I/O Priority Manager” that offers Quality of Service classes for DS8000 and XIV Gen3, and might consider porting this to other products in our portfolio.
Storage Optimizer was added to TPC 4.2 to help in this area, identifying heat-maps for IBM DS8000, DS6000, DS5000, DS4000, SVC and Storwize V7000. We recommend you look at the performance violation reports.
Yes, TPC can do this.
IBM’s Disk Magic modeling tool can take inputs from a variety of sources, including iostat from the servers themselves. You can also install a 90-day trial of TPC to help with this.
Yes, IBM has one also.
Thanks for the feedback.
TPC 5.1 has this support, and we believe it has been retrofitted to TPC 4.2.2 Fixpack 2, coming out this month.
Sounds like a great requirement to submit for the RFE process.
Yes, you can subscribe to it. You can also set up “ Watch Lists” .
