New IBM Z Redefines Mainframe and Security and Cloud
By now you have certainly heard of IBM’s latest mainframe, the long-awaited z14, which the company refers to as Z. An announcement of a new mainframe usually doesn’t attract much notice, but maybe this announcement should. Even if you are not a mainframe fan this machine offers a solution that helps everybody—pervasive encryption of all data with no impact on operations or performance and with no need to take much action on your part, except to plug the machine in.
At a time when organizations of all types and in every market segment are under attack from hackers, ransomware, data breaches and more; all data center managers should welcome automatic pervasive encryption. Yet 96 percent don’t. Of the 9 billion records breached since 2013 only 4 percent were encrypted! You already know why: encryption is a chore, impacts staff, slows system performance, costs money and more. You know all the complaints better than I do.
The z14 changes everything from this point going forward. IBM has committed a 4x increase in silicon dedicated to cryptographic algorithms for pervasive encryption. In effect the Z encrypts all data associated with an entire application, cloud service, and database, in flight and at rest, automatically. This amounts to bulk encryption at cloud scale made possible by a massive 7x increase in cryptographic performance over the z13. This is 18x faster than comparable x86 systems and at just five percent of the cost of x86-based solutions.
In truth, it’s better than this. You get this encryption automatically virtually for free. IBM insists it will deliver the z14 at the same price/performance of the z13 or less. The encryption is built into the cost of silicon out of the box. I have not seen any specific prices yet, but you are welcome to scream if IBM doesn’t come through.
You immediately get rid of all the encryption headaches; You don’t have to classify data, manage encryption or do any of the other chores typically associated with encryption. You just get it, automatically. The z14 also relieves you from managing encryption keys; Only IBM Z can protect millions of keys (as well as the process of accessing, generating and recycling them) in tamper-responsive hardware that causes keys to be invalidated at any sign of intrusion and then be restored in safety.
When it comes to security, the z14 truly is a game changer. And it finally will get compliance auditors off your back once they realize how extensive z14 protection is.
IBM downplayed speeds and feeds with the z13 but they’re back with the z14. Specifically, a 5.2 GHz (versus 5.0 GHz IBM z13) is still a bit short of z12, which ran 5.5 GHz. But as with the z13, IBM makes up for it with more memory. The z14 can handle 32 TB of memory. It also includes up to 170 configurable cores (up to 10 per chip) for a total of 1832 MIPS. The L1 and L2 cache is on the core. The L3 cache also sits on a chip and is shared by on-chip cores, and communicates with cores, memory, I/O and system controller as a single chip module.
Maybe not the richest specs, but impressive nonetheless. IBM has been tweaking the box from top to bottom to boost performance. And all the while it will take over end-to-end encryption automatically, including encrypted APIs. Surprisingly, IBM has said nothing about Z’s power consumption but constantly on encrpytion/decryption has to draw more power than, say, the z13. I am waiting to hear what IBM has to say.
This is not just for mainframe jocks. Optimized IBM z/OS Connect technologies make it straightforward for cloud developers to discover and call any IBM Z application or data from a cloud service, or for Z developers to call any cloud service. IBM Z now allows organizations to encrypt these APIs and still run nearly 3x faster than alternatives based on comparable x86 systems. These speeds and feeds have all been thoroughly documented and detailed at the bottom of the IBM Z press release here.
Will the z14 return the mainframe to positive revenue? Probably for a few quarters, maybe more if non-mainframe shops want the clear payback of pervasive encryption, although it won’t be an easy transition for them without IBM assistance and incentives.
